Title: Fracking
Post by: SA Chris on August 14, 2013, 12:18:00 pm
General dislike of Cameron aside, what do people think about fracking in general?

http://www.bbc.co.uk/news/uk-politics-23662583 (http://www.bbc.co.uk/news/uk-politics-23662583)

Personally it scares the crap out of me pumping all these nasty chemical underground, but how likely are they to actually get into groundwater? My geological knowledge is a bit limited.

One point in its favour - its a bit cleaner than coal. Everything else seems to go against it for me. The fact that the government are falling over themselves to invest in fossil fuels at this point in time speaks volumes; reducing CO2 output seems to have fallen off the political agenda completely... I despair.

Briefly (I have work to do today...)

the fracking planned/suggested for the UK is much deeper than many of the places in the US where there have been problems - and a much greater distance between the gas deposits and any aquifers. This greatly reduces chances of contamination. There is still an opportunity to contaminate water supply where the pipe goes through the aquifer and this depends on how well sealed the pipe is. AFAIK UK regs on this are pretty tight. So I would suggest its probably 'safe' in a general way in the UK. Of course transporting chemicals etc.. across the country, pumping them into the ground, ensuring their disposal, where to get large quantiies of water from etc.. are all opportunities for fuck ups and to lead to bad stuff happening... When operational they can sell the gas via the existing pipeline infrastructure which reduces our needs to import LPG etc..

BUT - for me the real kicker no-one in the media seems to be picking up on here is that its a carbon heavy form of energy. It would add to our CO2 outputs not reduce them.. In bigger picture terms its BAD for the world.. It might be great for the UK economy in the short term but... *sighs*

Fracking UK will also get very very generous tax breaks - and I lament how further advanced our RE industry might be if it were to receive such tax breaks... Whilst not a U turn, the coalition seem to have 'slowed down' on their promises for the renewable sector and greening the UK energy industry.

Overview: It'll probably be safe in the UK - but I disagree with it happening in the first place.

When I've looked at the US, it seems to involve huge numbers of wells in a grid to exploit an area. Presumably that would be the same here? I'm not sure how it will work given our rather denser population patterns.

The fact that we're all online all day shows that we has a great reliance on electricity. Our economy relies on it. Therefore we need, at this point, to use this reserve. There are some safety/environmental issues with fracking that must be acknowledged, however they seem to be far less significant than the damage done to areas such as the Niger delta through leaks/arson/terrorism etc. At least (global warming aside) it's our mess.
Title: Re: Fracking
Post by: SA Chris on August 14, 2013, 01:43:35 pm
There's no denying we need (and perhaps consume excessive amounts of) energy, but we need fresh water more. For ourselves and the food we eat. Alternative sources should be investigated, but I don't think fracking is a viable one.

As others have mentioned above the tax breaks could probably be better spent on RE options.

Post by: Stubbs on August 14, 2013, 02:05:50 pm
JB first of all I hope you know that the lighting your taps thing has nothing to do with fracking, but is naturally occurring in that area, I wanted to watch that film but the more I read about it the more I realised that there was a lot of bull in there in between facts.

I think if fracking was just happening in the North West and not Sussex then it probably wouldn't have the media spotlight so much.

What I didn't realise before is (correct me if I'm wrong) that this gas can't be used in power stations, and will only form domestic supplies, and as such they need a shit load more infrastructure to get it into households.

As a slight aside, from what I've read it sounds like successive governments have fucked up our energy policy to being at the point in the next few years that they may have to reinstate some coal power stations to make sure we have some breathing space in power production and don't start getting black outs.  Just another area where attempting to tender to private companies has failed.

Overview: It'll probably be safe in the UK - but I disagree with it happening in the first place.

TomTom's on the money.

The video you posted Johnny and many others like it have since been proven to be fake apparently. Even if it were caused by groundwater carrying dissolved gases as a result of the fracking process, it would be a lot less likely to happen in the UK. In the US, the laws on casing and securing well bores onshore are a lot less stringent than those in the UK, hence it's likely to be more safe.

On the issue on high density of wells, this is also an entirely valid point. Fracture density is important to extract gas from the very low permeability shale, you can't just pop one well in and expect it all to flow to the well as would happen in a conventional hydrocarbon accumulation in a permeable reservoir unit. Therefore, multiple wells are needed to open a large network of fractures (or reopen an existing network of fractures). A lot of older (some up to 30-odd years) fracking operations in the US rely on many wells in a small area in order for fractures to propagate around the well and join up with each other, and the easiest way to do this is to drill hundreds of vertical wells. However, since horizontal drilling and multiple well-head technologies have been developed, it's possible to drill many wells from one location and drill horizontally with one well to do the job many wells used to do, and also to drill many horizontal wells from the same location, greatly reducing the need for multiple well-heads as seen in the US. As the Bowland shale is very extensive and quite thin however, it'd still need a quite a lot of wells to exploit it, but not on the scale of the US (their prime fracking basin, the Marcellus shale, covers an area of two or three times that of the UK if I recall correctly).

Drilling and fracturing fluids used are often quoted to be 97% water (I think it has to be fresh, not saline) and the rest made of surfactants ("ones found in most household cleaning products") to keep things moving and proppants (physical fracture-keeping-open things) such as sand. One of the most important issues is that fracking is very intensive on water supplies, with water needing to be piped (but more likely carried in lorries) to the well-head. As water supplies in the UK are already at a tipping point (no new reservoirs have been built in the UK in the last 40 years, leading to an increased reliance on abstraction of water from rivers, endangering habitats and causing supplies to be running short) this is no good thing.

Of course, with such a valuable resource under our grounds, you'd think it'd be a good idea to let people exploit them and tax the frack out of it so we can pump that money in to renewables. Great idea, unless you're a Tory and your chums need to make a quick buck.

Fracking? For me, no, from an environmental and economic point of view. From a geological point of view, it's perfectly safe if wells are designed and cased properly (remember, natural hydraulic fracturing has been occurring underground for about 4.56 billion years and will continue to do so as long as there's water under the ground).

Suggest you watch the film 'Gasland' for a slightly biased view of how f'ed up the US got its approach to Fracking - there's no doubt it's caused some issues there but that's mostly due to poor control of drilling fluids rather than the Fracking process itself.

As for supposed issues with micro-tremors the media like to hype on about every once in a while, it's basically not an issue and bigger ground vibrations are induced by human activity all over the place on a daily basis.

With the correct controls in place I have no gripes with it as a potential energy source as, lets face it, it'll be a long haul before any of the 'alternatives' form a viable mainstream source of power supply.

Sadly - in the UK RE and in particular wind could have (by now) taken up a load of the slack fracking will probably fill... If we'd given the RE better tax breaks as well maintaining higher feed in taffifs for things like domestic PV we might not need it... There have been several days this summer when greater than 50% of German electricity production has come from domestic PV.. It can be done..

Working in Hull, its heartbreaking watching a fledgling RE industry stall because major European companies (in Hulls case Siemens) are holding back on investing - because of doubts on the coalitions commitment to RE and the EU....

Both RE and Fracking are in many ways sticking plasters to get over a short term gap in energy before more nuclear plants can be constructed - but I know which plaster I prefer...

I'm absoluately amazed that climate change has been so effectively wiped off the agenda. Such amazing short termism.

I knew that the recession was clearly going to hit renewables a bit, but I hadn't expected the wholesale "fuck the environment, we need to make LOTS OF DIRTY MONEY" attitude. I suppose most of the current raft of polticians puppets of the rich will be long gone by the time it really hits so they don't give a fuck.

I guess the fact that we will ALL have to take a bit of a hit to our living standards to prevent catastrophic climate change is just too big a pill to swallow...

that's where the extra optional cost comes in. It guarantees that the energy you use will be put into the national grid from renewables. You can have the standard tariff without the extra which does as you say. It's all in their details.

Carbon tax/carbon market - the way forward....

I sat next to a "Carbon broker" on Singapore > London a couple of years ago and he very well explained how a carbon market was starting to work.. for example, he was working with a bus company in India - that was replacing its fleet. This would cost c.$40m to do with regular diesel buses. Hydrids would cost $50m - but he could find someone wanting to offset their carbon emissions to pay the bus company $12 for the saved CO2 by moving from the diesels to the hydbrids - making it $2m cheaper for the bus company etc..

Along similar lines - my car as CO2 of 107g/km. If we price carbon at c.£10 tonne - then I could be 'paid' £500 a year for the carbon 'saving' over a regular car with say 160g/km (for my mileage etc..). This then starts to make peoples choices to a lower carbon product/usage whatever far more attractive.. If you place a value on carbon - then it shifts the economics significantly..

I'm sure there are many holes in my arguments - but bear with the concept - and until we (as consumers - as a world) are made to pay for carbon emissions they are not going to change... We can campaign and shout about it as much as we like, but sadly things will only change when the economics say so... $$$$ kerching.

first point. Ecotricity website explains plainly how they work.

Can't give a link for second point. Was an interview on radio 5 a while ago. When interviewer asked could UK meet all its energy needs from RE, the answer was technically yes. Which i took to mean, its the political will that is lacking.

Grey dull windless days negated by huge tidal potential round entire coast.

I was just pointing out there is a RE supplier that are cheap, committed to the cause and easily available for everyone. I agree with ecotricity,  the more people sign up, the more political pressure it puts on govt to invest in RE.

Also feeds into fracking debate. Gas from food waste and algae.

If we all dump the big 6 suppliers, just maybe we can tell the govt to frack off.

This is worth a read. Some points have been negated by new technology. For instance it makes the point that
south facing roofs would be better used for solar water heating than PV whereas the two can now be combined) &  I'm in no position to check the numbers but basically it's technically possible to get our current levels of energy from  RE within the UK borders.

However it would involve losing (or at least modifying) a lot of agricultural land which is another crisis on the way.
Ergo the plan to put the solar plants in places where some extra shade would actually help agriculture.

The tricky think with the UK domestic energy demands is that in winter we predominantly use gas for heating..

This is not something that can be readily replaced by electricity - well technically its easy but not many people will want to fork out the £££ to get rid of their boilers/radiators and replace them with alternatives..

Tidal can provide 24/7 regular power by using stations / facilities at different locations around the coast - but from what I've read only a percentage of our energy needs can be realistically met by this... (ie the potential is there but many of the sites are too costly to exploit)

True (to me) it makes sense to use gas where gas is the most suitable option - cooking, hot water and heating (when undertaken in the most efficient way; (an efficient boiler, a well insulated house, and the thermostat turn down to as low as necessary) but it doesn't make sense (to me anyway) to burn it to produce electricity. For all our other needs; lighting, appliances etc etc surely RE produced electricity is best environmental option.

Well except for barrages which are well proven technology. A Severn barrage could generate a significant percentage of Uk needs, but at an environmental cost in terms of habitat loss; an estuary with the second biggest tidal range in the world is remarkable for many reasons.

People at work have several contracts with tidal RE companies for their R&D... I've seen a few designs and sadly so far none have really proved their worth to my knowledge.. two real types of tidal power
1. Barrage type - retain water and release etc..
2. Tidal flow devices - things that you moor on the bed and they have impellers (or such devices) that turn as the tide ebbs and flows..

#1 works but as JB pointed out tends to have loads of environmental concerns etc...
#2 Works, but lots of issues to get around. such as bloody harsh environment, sometimes a need to move up and down with the tide to keep in the fastest flowing area, need to work over a range of velocities (during the tidal cycle), need to work in both directions (tide in, tide out etc..). Like wind energy there is also an economy of scale (larger leads to greater efficiency) but of course you only have so much depth of tidal flow...

Still its an interesting field and its encouraging to see a range of what start as 'shed' projects getting R&D funding up to prototype testing. Some nice examples of british inventors trying things out (and sadly so far not getting the magic combo..)...

I think severn barage and other tidal 'mills' should go ahead. Compare their minimal habitat loss to Chernobyl, 3 mile island, Fukushima, Windscale Irish Sea pollution etc.

Because of Hinckley Point and Oldbury nuclear power stations academic papers advise against eating resident fish such as flounder, because of toxic levels of mercury and cadmium in Bristol channel.

A wind/tidal power malfunction is a minor accident, a nuclear malfunction is a major environmental catastrophe.

I have had similar thoughts for years but it seems the technology is not there yet. I have reservations about big barrages due to habitat loss.

Personally I am strongly in favour of nuclear to fill the gap between weaning ourselves off fossil fuels and getting tidal/ solar/ fusion/ etc up to the required scale.

I am not convinced that the local environmental 'catastrophes' we have seen, even Chernobyl & Fukushima (http://www.theguardian.com/commentisfree/2011/mar/21/pro-nuclear-japan-fukushima), have had a worse effect on local biodiversity than, say, the average farm. A modern generation of nuclear power stations would carry less risk and produce less waste than the crumbling 60s relics that are typically held up to scare us. Nuclear is like flying - on paper it's the safest, but for some reason folk still find it terrifying. Being advised to not eat the fish is not the same as them growing a second head.

Why are barrages necessary for tidal power? I don't get why it's not possible to build just a few underwater turbines with foundations on a few piles in the sea bed without the need to totally enclose a body of water. Surely any moving water will generate more power than moving air?

Ahem... as I said earlier....
Lots of issues to get around. such as bloody harsh environment, sometimes a need to move up and down with the tide to keep in the fastest flowing area, need to work over a range of velocities (during the tidal cycle), need to work in both directions (tide in, tide out etc..). Like wind energy there is also an economy of scale (larger leads to greater efficiency) but of course you only have so much depth of tidal flow...

And to add to that.. in many estuarine and marine environments (e.g. Severn, Humber - and places like Menai straights) the bed is mobile - ie its silt and sand, so moves about throughout the year as well as over longer time scales. This means that your impeller/turbine can be swamped by a sand bar (for example) or the fastest area of flow could move to the other side of the estuary - where your turbine is not...

Yup, all of which would be issues if it was a barrage (except maybe last). And all of which are issues which are dealt with by offshore O&G industry and other industries (like harbours) on a daily basis.

I'm sure there are problems, I'm just saying that surely tidal doesn't have to equate to barrage ?

Bear in mind that a promising wave power program was cancelled in the 70s because the govt of the day 'lied' (they claim a convenient mistake) about the cost of nuclear . What's stopping development of RE is lack of govt funding & the only way nuclear is going to get built is by throwing huge amounts of govt money at it.

We need to solve this (in reality ten years ago) & nuclear has always proved expensive & slow to construct.


Title: Re: Fracking
Post by: tomtom on August 15, 2013, 03:54:08 pm
Barrage is actually much simpler. Just thick sea wall enclosing a body of water. You then make a couple of holes in the wall and whack your turbines etc.. in there.. Folk have been doing the like for 100's of years. Sure, its loads more concrete, but much simpler and you don't have to worry about many of the challenges I outlined earlier..

The forces are also pretty high, with tidal flows going up to 3-4 m/s which means you have to have pretty strong anchors/foundations/piling etc.. The problem as I see it is that to generate enough electricity you would need (say across a tidal bay/estuary) 10-20 spread out across it instead of one big one... this makes your infrastructure, cabling, piling blah blah blah that much more expensive..

The tidal 'potential' in the UK is huge - but what is economically usable (once you factor in the engineering) is less huge...

Sorry if I'm sounding a bit down on it - like I said at work we've seen quite a few come and go - and go bust... There are also the tidal power devices that need electricity to generate electricity :) thats another chestnut...

If the cost is comparable & (remember that we have no reliable figures for the cost of nuclear from start to finish as it's never been done) then I'd rather see the money go to a  Desertec style project I mentioned earlier.

Desertec is a lovely idea but exactly the reason why we need new nuclear asap, to replace the fossil fuel base and bridge the gap to such technologies. PV in the desert might be current tech but storing and moving the power long distance is not, nor have we seen too many models of such international cooperation.

Some interesting comments on this thread. As usual with UKB there are a load of "good" evidence based points where people have researched a bit around the topic. However statements such as the following are misleading and do not give a correct picture of the environmental impact of different energy options.

I think severn barage and other tidal 'mills' should go ahead. Compare their minimal habitat loss to Chernobyl, 3 mile island, Fukushima, Windscale Irish Sea pollution etc.

Because of Hinckley Point and Oldbury nuclear power stations academic papers advise against eating resident fish such as flounder, because of toxic levels of mercury and cadmium in Bristol channel.


Are you really saying that Chernobyl, 3 mile island, Fukushima and Windscale Irish Sea pollution have caused more habitat loss than a potential Severn Barrage? If you truly mean this (and I have understood you correctly)  then you are clearly mis-informed. What habitat loss has been caused by the afore-mentioned nuclear accidents??? Yes, they resulted in the release of radioactive contamination into the environment. However this has NOT resulted in any substantial long term habitat loss.

The largest "habitat loss" in any of these cases is probably at Chernobyl, where the enforcement of the 30 km exclusion zone has removed people from this area. Only a very small number of species that commonly co-exist with humans have been effected, e.g. there has been a reduction in the abundance of barn swallows. The vast majority of species have benefited from the abandonment of contaminated land. If you have access to an academic library see the following as a starting point:  Pikulik, M. M. & Plenin, A. E. 1994 Dynamics of the biological diversity of fauna of Belarus after the Chernobyl nuclear disaster. Radiation Biol. Ecol. Special Issue, 33–34

Anyway I digress. It is good to see a debate surrounding the wider energy mix, than just "no fracking". At the end of the day we need to get our energy from somewhere. The difficulty is deciding which environmental impact is the most acceptable: habitat loss from tidal barrages, potential environmental contamination and long term waste storage issues with nuclear power or carbon releases from fossil fuels.

These impacts needs to be weighed up against one another. There is no such thing as energy without an environmental impact. It just depends what you think the most acceptable impact is...

It's thermal not PV so really old tech (in concept) & no need for storage. The infrastructure for moving it is , as you say, the expensive bit but I can see no reason it can't be as accurately costed as any big infrastructure project ( I doubt that can be said of nuclear)

Outlawed - I like your passion for the debate..

But Tsunami risk in the UK is tiny - and those that historically have struck were small (1-2m) - their impact was probably much greater as there were effectively no coastal flood defences in that time.. Most of the East coast is protected against surge tide heights, so it would be unlucky for the very rare tsunami to hit at the same time as a king tide... (I'm not sure how you'd get one from the east coast..). Chris - the Canaries mega tsunami theories have recently been debunked my Tusnami/Landslide/Volcanologist colleague tells me (there were mega landslides, but earlier studies cocked up the tsunami estimation)..

I used to set my first year tutees (I'm an academic if you hadn't guessed) a 'get them warmed up' type essay on 'compare the impact of nuclear vs coal power on humans'. If you do a straight body count - then surprisingly (to them usually) you find that a few dozen people have died immediately after nuclear incidents (direct result) and c.5-50 000 total (make up your own numbers really in this range - that seems to be what the journal articles do) from shortened life expectancy from the accidents (mainly Chernobyll). When you look at coal - there are hundreds to low thousands of people every year who die in the extraction process (mining incidents etc..) - and several thousand to 10 thousand (per year) who have die prematurely due to the pollution of burning the stuff..

Its easily if not more 10:1 Coal to Nuclear in the body count... thats before you start factoring in any global warming effects which will start to come in at some point..

I appreciate the jist of this thread debate is more towards RE vs Fracking/Fossil fuels - but I think we need to consider that Nuclear power is possibly the lesser of several evils.

Put it another way - I've done some work at this place: ranger uranium mine in Australia. Its not an especially big pit (its tiny in the open cast mining scheme of things) but at one point in the early 90's, uranium from this mine was generating 10% of the WORLDS electricity... thats just one small (comparatively) sized hole compared to the huge tracts of the earth being removed for coal open cast mines...

If the precautionary principle was used to that level we wouldn't be able to do anything! What if there were a big earthquake in London? It would fall down! By showing you fear a UK Tsunami shows you have no ability to assess risk, and thereby rather undermines your assessment of the risk posed by nuclear.

Well for one, no one is suggesting putting a plant in my garden. If they were to bury it with the kind of schemes mooted, in suitable geology I wouldn't give a toss, no. Far too much emotion and not enough judgement in this debate. Which coming from climbers, whose hobby involves assessing risk, is disappointing.

Secondly though, and far more importantly, if we were to build an IFR, the current waste would be the fuel, and it would be recycled until none were left (http://www.theguardian.com/environment/2012/feb/02/nuclear-reactors-consume-radioactive-waste).

Humans are very good at assessing risk in a situation where the outcome has immediate (or short-term) consequences.  Far less so when the consequences span just a few generations (living in deltas or on/near fault lines), even worse when its geological time scales.

Paragraphs 10 & 11

Quote
In 1982 Salter invented the idea of a mechanical "duck" which bobbed on the ocean and generated electricity. But the government shut down the UK Wave Energy programme, arguing that his invention would be too expensive to develop further.

It emerged later that civil servants in the nuclear power division of the energy department had "miscalculated" by a factor of 10 the estimated cost of energy production, possibly setting back British wave energy research by 20 years.

I think we've missed the boat for RE, the cynic in me thinks this "mistake" had some pressure from the Nuclear lobby, which was pretty strong in this time period, but it doesn't really serve the current argument to look back to the 80s and think "if only". I'd like to know what it will look like to look back to now in 2020, or 2050. What are our current "if onlys..." is it nuclear? development of RE? I'm pretty sure that all the figures I've seen for RE didn't cover total usage, but also required a drop in consumption, hoping for the silver bullet of "efficient technologies" to enable this is a bit of a pipedream, so what are our realistic options?

I remember an interview with James Lovelock on the radio where he stated he'd be more than willing to have nuclear waste buried in his back garden, it would mean free energy for life for his household (but then he also discussed about how he invented the first microwave to warm up dead frozen rodents for lab experiments, maybe the man is a little less squeamish than the rest of us..)

My brain can't really compute the problems of climate change, however each time I read articles that commensurate the scientific consensus it does fill me with anxiety, more for global equality than much else. But then, in 50 years time, will Britain still be at the top of the food chain? I doubt it, so maybe we should be worried... We're only a little island, a few metres of sea level rise could devastate us....

On the link you posted earlier tomtom it seems to suggest that a gas economy would limit carbon PPM to 650, which in turn still creates a 3.5 degrees temperature rise, and thats without possible complications of methane escaping during the process... Suddenly fracking seems alot less suitable as a stop gap... Coal is definitly not the answer, nuclear is far too lagging as is development in RE, does this mean we've fucked it?

All we've been discussing so far is electricity generation & that's the easy bit.
Technically it's a solved problem. Either nuclear or desert solar would  provide a solution (in combination with wind & PV) if they had been or get  built.

Transport (air road & sea) & agriculture both use massive amounts of fossil fuels & there isn't a technical solution for that in place yet.

As to whether we've fucked it yet: my understanding is that the climate isn't well enough understood yet to know but my approach would be "when the ship you're on starts to sink you start bailing! You don't calculate the size of your bucket & the distance to port then give up. Better to drown  in 2 hours than rather one & you never know.

There are technical solutions readily available; use cars less, use the train, feet, bike, car pool, hybrid bus more. Reduce commuting distance if possible. Buy local produce, be a considerate consumer, reduce, reuse, recycle etc etc etc. If everyone in the UK did this and/or was encouraged to do it more by making it more palatable (by either financial sticks or carrots) then our dependency on fossil fuels would be drastically reduced.

Fultonius, the "government" aren't that smart or sophisticated enough to organise any energy policy, never mind one that was a stitchup in favour of gas.

An interesting footnote to the 60's and 70's development of fission reactors was that they were a vital source of material for the nuclear arsenal at the height of the Cold War.  My Dad worked for the NEA during his career and was a bit disillusioned to find out the power stations were built to feed the munitions industry. 

For the record im generally in favour of fracking to reduce dependence on Gazprom and Rosneft for gas supply.  The regulatory and HSE requirements are much more rigorous here than in the US.   Investment in Nuclear for the longer term is a necessity.

I agree with FD on his last points. I have taken a little bit of time to read about Fracking having been asked to sign a petition against it. (i wouldn't as i said i knew nothing about it, unlike a lot of people i was with who happily signed away in ignorance). From what i read it seams pretty safe if done properly and a lot of what is being pushed by the anti lobby is just not true. The only issue that might cause issues is the extraction of water for use in the process especially in areas of the country already short on supply.

The use of gas for electricity production seems to be a necessary measure and one that is better than coal and its our own supply which surely must be a benefit. However it is not the longer term answer as it to will eventually run out.

In my opinion renewables face more problems with planning than any other source. Nobody wants them in their back yard. The opposition to wind power where i live is unbelievable yet they are digging up vast tracts of countryside for coal with hardly a mutter. And often its the biggest supporters of renewables (walkers, climbers, country folks, surfers,bird watchers etc etc.) who are the ones up in arms when they try to build in there favorite spot.

Bowden Doors is effected at the minute and everyone is up in arms many of whom only go there a few times a year. To me it seams a perfect place to put one, low density population and fucking windy as anyone who climbs there can testify. If they can prove that they work (jury out) then they should be able to build them there.

Same with wave and tidal power. As soon as one is proposed near a surf spot the "may" effect the quality of the waves the surfers are up in arms.

Planning laws need changing and the energy policy needs to be decided by non political bodies who can see further than the next general election. What ever we do to benefit the future has little chance of benefiting our generation but we have to get on with it, pay for it and live with the cost.

Wind energy plans were part of the 'stopgap' put in place by the last government before nuclear could come on line (20-30 years).

I've been in seminars in Hull - where in the North Sea offshore wind turbines should be commissioned at a rate of 1 every 5 days from 2015-2020. Its a very large number - and the turbines in question are typically twice the size of the largest on land. But whilst not stopped many of these plans have been slowed down considerably by the energy co's seeing a cooling on the idea from our present government. The Wind co's need to have a gaurunteed min price for 20 years etc.. in order to put the things in and the word from the Government has not necessarily reassured them. Along with wobbles about whether we will be part of the EU in 3 or 4 years time.

The tidal 'potential' in the UK is huge - but what is economically usable (once you factor in the engineering) is less huge...
Catching up with this interesting debate had me reaching for the only resource I use on this stuff: sustainability without the hot air (http://www.withouthotair.com/download.html). This awesome book is free to download.
Nice section on tidal - MacKay points out that the entire North Sea is in fact a tidal pool and tidal stream farms could in principle be constructed - though no one yet did this so it is a long way off.
He reckons maximum conceivable (cost no object) tidal energy production for the UK is 11kWh per person per day (having converted total production into this unit for ease of comparison). Other studies suggest more like 4kWh pppd. For comparison average energy consumption is about 125kWh pppd (in the UK). So tidal could contribute and is reliable but is only part of the solution - and only then if someone figures out how the hell to harness it.

As has been touched on, a big issue with a lot of renewables is that they are not reliable and we dont have much storage capacpity. I think most reasonable options for hydro pumping storage (e.g. Dinorwig) have already been developed in the UK. The problem renewables typically fail to deal with are how to (a) guarantee accommodating peak demand and (b) ensure frequency regulation (as demand fluctuates on a second by second basis you need to keep frequency matching). We need quick-response generation facilities for this - i.e. not wind or solar.

There is also the problem of slow start up and shut down speeds of many power generators. At night (under low demand/base load) even when the wind blows and the operator "flips the switch" to use wind farm generation, they cannot simply shut down a coal power station for 2 hours - they simply let it "piss into the wind" and nevertheless happily can claim another 0.2% (or whatever) of UK electricity came from RE - despite the coal still burning! These sort of generation facilities are also often kept running as "hot reserve" ready to be used when demand bumps up.

One final thought (a depressing one - apologies). My synopsis of a talk I recently heard given by an economist is that *all* the fossil fuels we can manage to extract will be used up - it is only a question of over what period of time. This is because the extraction cost is so much lower than the market price for oil, gas, coal etc. So economics says "we will use it ALL". Unfortunately it seems that we/someone will.
It reminded me why I've never been a fan of economics...

Its also worth noting that the sites in the UK are heavily bunded - so they obviously have to oblige by the same regulations for storing chemicals on site as anywhere else...

Bunds are generally designed to keep stuff in. So if you have an oil spill - it can't leak down or sideways.. But (to a degree) would do things the other way around. No way you'd be allowed to keep open stores of oil/chemicals/contamianted water in a flood risk area.

One of the main findings from the 08 Pitt report following the 2007 floods was a need to assess critical infrastructure situated in flood risk areas (power stations, water treatment works, bouldering walls etc..) in order to protect them from future events etc..

But frackers can obtain that permission under compulsory purchase order. You can't stop them but you can haggle over a share of profits. Relevant case summary is here (http://www.supremecourt.gov.uk/decided-cases/docs/UKSC_2009_0032_PressSummary.pdf). In this case the drillers didn't obtain permission and so trespass was found against them, but in the end no damages were awarded because there was no possibility of loss to the landowner (Mohamed Al Fayed) whose property was drilled under.

I don't have much of an opinion about fracking as I've not done enough reading to make an informed decision.  I linked the above story not specifically because of fracking but the pernicious way the government have gone about gandering support for it by putting the squeeze on councils and then dangling a carrot in front of them if they go with fracking.  I'd rather see such efforts used to encourage development of sustainable/renewable energy sources as fracking is just as finite as all other fossil fuel resources and adds to CO2 emissions (an obvious downside which I don't need to do much reading to work out as its self-evident).

I've thought for a long time that whilst the technology for nuclear fission, solar, wind, wave and tidal are being developed we should fall back on nuclear fusion.  Its too late now, but it would have been great if more work had been done years ago on using thorium (http://en.wikipedia.org/wiki/Thorium_fuel_cycle#Advantages_as_a_nuclear_fuel) rather than plutonium or uranium.  Far, far superior in terms of abundance, greater energy output (in part from the breeder reactor aspect), substantially lower half-lifes so less problematic waste to deal with, although it needs a kick-start from something like Uranium and there are other drawbacks as Wikipedia explains.  It was clearly ignored as it didn't have the handy artefact of producing fuel for nuclear weapons  :wall:

I see. So wind farms are ok, despite the huge loss of efficiency of cabling ashore the electricity. And despite the fact that there is virtually no long-term evidence of how much maintenance and down-time the turbines require. It's already becoming apparent, 5-10 years down the line from the first offshore windfarms going online, that the quoted lifetime for blades and motors are way too optimistic - the rope access technicians who work for me have been repairing blades at a rate of every 2 years - not the figures given by manufacturers (7-10 years). I predict another Trawsfynydd on a large scale (nuclear cocncrete monolith in the middle of Snowdonia, useful life of 20 years, for those unaware). Offshore wind power is a massive ripoff and we're going to wake up in twenty years, look out to sea and wonder what the fuck we were thinking. IMO.

Tidal barrages are ok? But the impact on estuary wildlife is quite severe from the studies I've seen/heard about? Kill the fish and birdlife, as long as we don't emit carbon  :-\  Just saying.

Nuclear is ok? - why is nuclear acceptable and fracking isn't? Because it isn't carbon-emitting? What about the inescapable fact that we have to have gas - for heating and to fuel gas-fired power stations -  nothing is going to change that in the next 15-20 years so it makes a lot of sense to have our own supply of gas instead of importing it via pipelines and LNG shipments from Russia.

Have a look at the pics of  the Yorks/Notts coalfields 30-40 years ago.. or the coast up nr Sunderland when they were chucking the coal waste into the sea.. Prefer that to rows of matchsticks on the horizon of an offshore wind setup?

Been over to Easington recently - or the LPG terminal in Pembroke? Attractive non? Ah - I forget the concentric rings in my cuppa that the 6 trains that rumble 1/2 mile past my house every day (in Hull) leave on their way from the docks to Drax...

Google open cast coal mining. Or have a look at pics where the oil sands being mined in Canada at the moment.. luuurvely...


As a developed country - I think we are in a better position to make choices about where our energy comes from than many nations. And I think these choices should be less carbon intensive....

No I'm not - you're completely missing my point. My point is not that it's not ok to use coal or gas from Eastern Europe - I think that's retarded, so blatantly retarded. But we therefore need something other than Eastern European coal and gas. And Wind/Tidal isn't going to fill the gap, so what is going to fill the gap? Nuclear. Except that takes 15-20 years to build. So what are you going to use for the next 15-20 years? Now fracking comes along, of course it makes sense compared to the 'alternatives'.
Fracking versus coal/gas from Eastern Europe. Shit versus double shit.

Windfarms - they aren't on 'the horizon'. They're right in front of my nose everyday I look out to sea from Llandudno. The horizon is 22 miles away, the windfarms are right fucking there.. They piss me off a little bit. And they're covered in lights at night. And they're inefficient and constantly needing repair. In short they're bollocks and I'm convinced there's a French dude pissing himself laughing at our expenses for being such muppets to buy hook line and sinker the bullshit sold to us by energy companies, because we thought it would be all green and cast rainbows.

I actually worked on the oil sands in Northern Alberta for two and a half years, at 3 of the (then 6) refineries and have seen first-hand the damage, pollution and scale of the place and know how many mega tonnes of carbon Suncor and Horizon emit per year, which is why I know trying to save carbon with windmills is a drop in the ocean, literally.

You're correct about the energy gap - wind cannot meet this, tidal could definitely offset some of the gas (both open stream as in the Pentland Firth 86MW tidal array and barrages - yes, it'll fuck up some habitat, but it'll be the very same habitat that gets fucked by the rising sea levels.)

So, gas is going to play a big part in the next 15 -30 years. No one in industry (green or fossil) will deny that. We have made our bed by being too slow and too weak to sort out any proper alternatives and we will have to lie in it.

Now, we have quite big offshore gas resource in the UK. There's still plenty gas out there and it's well known how to get it out and what the side effects are. Fracking just seems immensely risky when you look at the previous attempts. Why bother?

Right, let's start with the word I hate the most when comparing low-carbon vs high-carbon energy sources: - Efficiency. It means nothing. Really, the only metrics worth discussing are the cost/unit energy (£/MWH etc.) and the carbon (and other) emissions.

Put it this way, let's compare coal to wind:

Coal - ~40% "Efficiency"
Wind - 20% to 40% (dependant on wind spee)

What does this really tell you? Nothing. One technology needs open cast mines, rail and ship delivery etc. The other uses wind - who cares if it's not used very efficiently, it's free!!

So, then you have to think about the cost of constructing each and the price of the fuel and the cost of running etc. Then the picture gets worse for wind, especially offshore, as coal is still a relatively cheap source of fuel when you add everything up.

That's why we need either subsidies, or a carbon tax, to make cleaner energies seem cheaper.

In my mind we have 2 alternatives - 1) Keep trying to convince ourselves that we can live of cheap energy and continue to fuck the planet - nice long term thinking there!
or 2) accept that the cost of living is going to have to increase for a while to prevent serious damage to the environment.


The bottom line is, it seems your main objections are based on: Looks, a bogus belief that efficiency matters and not really accepting that we are fucking the planet with carbon and other emissions.

Do you think that because wind can't cover all our needs we shouldn't have any?

Our present wind and RE expansion plan (that has gone on hold since the change of Government) along with an expansion of gas power stations (that does not seem to have gone on hold since the change of Government) was designed to fill the energy gap. But wobbles in the future of the tarrif paid, whether we are going to be in Europe or not have seen the big RE companies stall or in some cases pull out. So we now have a larger energy gap. At least thats what the wind RE people I know have told me..

There is a lot of NIMBYism around the windfarms, I feel the opposite, they make me feel happy every time I drive past them at the thought of energy being created from thin air! The idea of them needing repairs and having down time as a point against them is laughable; I'm sure you will have driven along the M56 and seen one of the Ellesmere Port refineries flaring off fuel because it's too expensive to turn the cracker off?  Having downtime on a turbine seems somewhat sedate in comparison.

Title: Re: Fracking
Post by: slackline on January 14, 2014, 10:04:09 am
I see. So wind farms are ok, despite the huge loss of efficiency of cabling ashore the electricity. And despite the fact that there is virtually no long-term evidence of how much maintenance and down-time the turbines require. It's already becoming apparent, 5-10 years down the line from the first offshore windfarms going online, that the quoted lifetime for blades and motors are way too optimistic - the rope access technicians who work for me have been repairing blades at a rate of every 2 years - not the figures given by manufacturers (7-10 years). I predict another Trawsfynydd on a large scale (nuclear cocncrete monolith in the middle of Snowdonia, useful life of 20 years, for those unaware). Offshore wind power is a massive ripoff and we're going to wake up in twenty years, look out to sea and wonder what the fuck we were thinking. IMO.

Tidal barrages are ok? But the impact on estuary wildlife is quite severe from the studies I've seen/heard about? Kill the fish and birdlife, as long as we don't emit carbon  :-\  Just saying.

Nuclear is ok? - why is nuclear acceptable and fracking isn't? Because it isn't carbon-emitting? What about the inescapable fact that we have to have gas - for heating and to fuel gas-fired power stations -  nothing is going to change that in the next 15-20 years so it makes a lot of sense to have our own supply of gas instead of importing it via pipelines and LNG shipments from Russia.

Its disingenuous to polarise one energy source v's another v's another as the solution isn't one or the other, but a bit of everything that is required accompanied by a reduction in consumption.

All have pros and cons, and that includes fracking the disadvantages of which are highlighted elsewhere in this thread, but with current usage levels there is little choice.

Me too.

Plus the early signs are that offshore windfarms are very good news for biodiversity. The foundations create artificial reefs and, more importantly, the trawlers can't get in amongst them. You won't get such spin-offs from fracking.

I also think they are becoming a serious source of power faster than people realise.  In Denmark, wind energy output exceeded 100% of the country's needs on Nov 3rd - not just powering a whole country but generating export profits too! In 2013, they provided more of Spain's energy than any other source (21%). In Portugal, 70% of power was generated by renewables in Q1 2013. We are a little behind in the Uk, but last month wind provided more than 10% of total energy needs for the first time - peaking at 17% on the 21st Dec.

Post by: petejh on January 14, 2014, 11:02:50 am
I'm not anti wind, anti gas, anti nuclear, anti fracking, anti coal even.

This is what I'm anti. I'm anti people whinging and bleating about the inevitable development of opportunities as they arise, especially if they can't propose an equally good realistic alternative. Bleat on about Thorium and tidal arrays, I agree everything should be pursued. But Thorium isn't going to heat your semi-detached anytime soon, or supply you with electricity.

Gas is required now and for the medium term. Virtually everyone still needs oil for transport and manufacturing. I'd give even the most ardent climate-change neurotic 7 days in a country shut down due to the oil and gas supply being cut off, before they developed a new set of beliefs about climate change.

The bigger picture - shale gas in the UK hasn't 'only just' become known about, it's been known about for years but the political and economic picture didn't make it worth pursuing. Now Scotland are possibly splitting in the near future and suddenly, as if out of thin air, shale gas comes over the horizon (one covered in windmills perhaps). Shale gas is a very sensible hedge against volatility surrounding Scottish North Sea oil/gas. Also, it's a very powerful political hedge against one of Alex Salmond's biggest bargaining chips.
The political picture changes as soon as the rest of the UK, post Scotland leaving, have a secure supply of gas for the next 20 years thanks, and perhaps as a consequence the price of gas goes down - and part of Scotland's future revenue stream suddenly doesn't add up to as many billions as it did prior to shale gas being developed. I don't think it's a co-incidence that fracking is being fast-tracked this year of all years.

Pointing out that windfarms need downtime and repair = laughable? What? Why is it laughable to point out the cons of anything? I too get a glowing feeling from seeing turbines producing electricity on windy days - that's one of the pros. But it's sensible to question how much total electricity a turbine produces and to point out that the downtime due to blade and motor repair is way higher than originally claimed by the energy companies and investors. I was speaking to someone last week and they were telling me about the carbon fibre repairs they'd carried out on blades and how they last about 2-3 years in some cases before the next repair. Windfarms have just as many investors looking for good returns as any other investment opportunity, they aren't some angelic creation there for the greater good. Consumers will foot part of the cost if wind farms aren't profitable. I've got serious doubts we'll be thinking the same about wind farms in 20 years time if the current schedule of downtime and repair is anything to go by. The electricity they produce also isn't 'free' - the time, money and public/political will invested in wind farms are all finite resources which haven't been invested in some other source of electricity generation (Thorium perhaps...) as a consequence.

It's amazing and interesting how an opposing voice in debates like these often gets labelled as that of a climate-change denier - hence:
Secondly if that's your stance re: other countries having massive carbon outputs (China 'winning' by miles) why would you be bothered at all about us using gas from Asia and Eastern Europe, we may as well get on with it as we are not the worst right?!

Where have I said  that!?? You're putting ideas into my post that I didn't type and don't think.

I do however think if you're trying to make important decisions then you need to try to understand as much as possible about the larger context, and understand what saving some thousands of tonnes of carbon actually means overall. Especially if you're using 'saving x thousand tonnes of carbon' as a justification for something. It isn't defeatist to understand that it might not really make any difference in the long term to make compromises in the short-term. I also don't think any UK political party has that sort of long term policy, but that's a whole other discussion. The public and media aren't blameless there for not allowing a system to exist in which long term policies are allowed to  take precedence over short-term gratification.

This sounds like an extremely spurious point. I doubt very much if sea levels will rise quick enough to 'fuck up some habitat'. I think its far more likely rising seas will force cultivated land to be handed back to nature. I did an access job a few years ago involving exactly this - knocking down the sea wall on the Essex coast to return good farmland to saltmarsh and hence reduce storm surge pressure on the Thames barrier.

Whereas I think tidal barrages will have a serious effect on habitat. I'm undecided as to whether the benefits will make this worthwhile, and would prefer to see tidal turbine arrays developed.

Precisely. Common in debates about energy/climate change are fallacies such as 'building scheme x will directly result in sea level rise' or 'not building scheme y will lead to sea-levels rising'. 

There's a theory which describes how, in order to invent and put into mainstream use new, non-fossil-fuel, energy technologies, you need current sources of energy or else the whole system collapses in on itself. This is how I see shale gas, oil, coal, gas, wind, tidal, solar etc., as current sources of energy to hopefully enable us to get far enough down the road to better technologies. If we run out of current energy sources too soon, or run out of the will to keep pursuing the expensive alternatives (in terms of investment and energy expended) it's called the energy trap:  http://physics.ucsd.edu/do-the-math/2011/10/the-energy-trap/ (http://physics.ucsd.edu/do-the-math/2011/10/the-energy-trap/)

Climate change is something different again. An unintended consequence which we're going to have to endure and try to manage the best we can, because the consequences for the developed world of falling into the energy trap might be far worse than the consequences of climate change (for the developed world. For the developing world it's the other way around).

It's not that you failed to convey it (and I'm not aiming posts at you in particular). It's more that the overall tone of discussion on here is often: whatever the conservatives propose gets automatically vilified. Maybe that's justified in some cases but something like this is far more complex than just conservatives or labour. All parties would be pursing shale gas sooner or later.

Shale gas isn't the problem in itself, it's how it's extracted and what's done during the 'time and energy window of opportunity' created by using it that are the important bits.

Ok, fair point. My point was that really we have to start doing something because every year that we sit around arguing over which way is "best" is another year lost.

The Severn tidal barrage really is a separate issue and debating whether habitat loss is worth the power produced is going to side track this discussion.

It was the nefarious way in which 'bribes' for local authorities (LA) were being proposed to promote fracking over everything else.  These were likely in the background for a long time and part of the reason the squeeze has been put on LA's, as government knew they could promote their mates (and no doubt some of their own) vested interests in the companies that will profit from fracking. 

It just stinks of the typical  :shit: that seems pervasive across all political parties/most politicians (there seem to be a few who are genuinely interested in doing whats right rather than what will get them re-elected but they are sadly in the minority and dwindling these days).

...

There are two separate issues here.

One issue is climate change.

The other issue is to do with the consequences of developed nations going into declining total energy supply. More precisely, running out of the political and public will and financial resources to change over into new technologies before financial and civil breakdown.


The two issues are obviously linked, but to get context on the consequences of climate change you need to understand the consequences of developed countries going into declining total energy supply. The energy trap describes a possible set of consequences. Once you've read and understood that you can then decide whether carbon-emitting energy sources are 'worth it' in the short, mid or long term.

Nuclear is what we should be using to transition off fossil fuels to renewables, not shale gas. Unfortunately it suffers from a terrible image problem due to nuclear weapons and scaremongering surrounding old technology. The real risks from a modern plant are far less than a typical coal-fired power station.

France generates >75% of its electricity from 58 nuclear reactors, with the cheap energy produced making them the world's biggest exporter. They had a couple of minor meltdowns in their early reactors (most recent 1980), both long decommissioned now.

I don't have a lot of time to enter into a debate so apologies if I don't respond either in time or with huge paragraphs.

When "fracking" was first developed in the US it was a real experimental situation, a classic case study of innovation.  Unfortunately there are often consequences to experimenting in the real world rather than a lab, especially in a low regulatory environment like the US.  These consequences. Ground water pollution etc were largely down to (a) early stage technology (compare primitive oil wells with the very safe and secure technology in use today) and almost zero regulatory oversight.  Hence lots of issues and films like Gasland.

The regulatory environment in the UK is much, much more stringent here than in the US and I'd rather see the UK developing its own shale reserves as part of our developing energy portfolio for the following reasons.

Economically were are a net importer of gas into the UK, if we're were able to produce more of our own, spot prices would drop (the fall in US has been dramatic) leading to lower prices, particularly for industrial consumers and several of the mothballed steel plants in the more economically depressed areas of the UK could easily open again.

Our environmental regulatory environment is very, very stringent compared to North America with real consequences for those that fail to comply so I wouldn't expect to see any of the stuff that goes on in Gasland, especially that the US have developed the technology to a much more effective and efficient standard than ten years ago.

It will create jobs in the North of England and Wales.

From an energy security perspective, I'd rather be producing our own gas than buying it from the KGB (Rozneft and Gazprom) or OPEC where gas purchasing influences our attitude to oppressive regimes in the Middle East.

Prices will drop for consumers and more cars will be be able to use LPG.

Should lower gas prices necessarily be an aim?

I understand that there are economic benefits (but I think JB is right about needing a kick up the arse with regards to continual economic growth as its ultimately unsustainable), but lower prices discourages people from minimising usage (or conversely higher prices encourages conservation), certainly at the individual/household level.  Perhaps just stabilising prices would be preferable (or at least keeping their rise in-line with other aspects of inflation so that they don't become a major driving force to inflation itself).  :-\

I pretty much whole heartedly agree with falling Down on this one, other than the point about it bringing down prices, which i don't think will happen. I personally think the obsession with the price of fuel is totally wrong as i think that if it continues to go up it will force us all to look at reducing our usage and make the cost of house insulation, new windows or individual power generation etc more economically viable.

In the short term we really don't have any viable options other than the use of fossil fuels and the arguments against fracking seem to be based purely on Nimbyism. Other than the actual burning of the gas the environmental argument seems pretty weak to me. At present we are happy to import gas from other countries but don't want to extract it here.

Long term nuclear projects, coupled with wind, tide and solar are the way forward but again they get blocked by nimbies who do not want them sighted next to there house or favorite view.

I can now see a pretty big wind farm from my house, Middle moor and Wandylaw development of 28 turbines, but it does not bother me in anyway and i refused to sign a petition opposing them, a petition signed by a majority of the middle class populous of the area who signed purely on the basis that they spoil the view. I would happily have one in my garden for my own power generation but absolutely no way i would get planning. As its estimated we would need between 50000- 75000 wind turbines to provide 50% of our power requirements we are going to need a lot more views ruined and a lot more acceptance from the general populous, which just is not going to happen.

Therefore as far as i can see we need gas for a good few decades yet so why not use our own supply.

And one final point, i wish people would stop using this as party politics, is not a Tory issue or a Labour issue its one that really needs to be looked at politics free or we will never get an answer.

Seems an eminently sensible idea.  Not got time to read how much it can produce though.


I should add a caveat I thought of whilst cycling this morning to my above question about not aiming to reduce energy costs. Keeping fuel prices high is a good way to encourage reduced usage, but....

...no one should have to live in fuel poverty.

The need (energy security/availability) is non-polictical - but the solution is highly political.

Theres no way around that. Many vested interests on both sides - as well as ideological differences in how this should be solved.

IMHO fracking in the UK will probably be safe and well regulated. But it signals an intent to continue to be fossil fuel based rather than alternatives. 

I think this is a bad idea - and we will miss an opportunity to move to less carbon emitting methods. Fracking kicks the can further down the alley - but also allows the alley to become dingier and more dangerous!

The argument 'we all have gas' so we can't change etc.. doesnt wash for me. Things can change and can change rapidly. Look at the uptake of domestic PV in Germany and Spain - how rapidly that has expanded in 5-10 years.

What he said, though I'd prefer us to go balls out for nuclear too. Shale gas is still a fossil fuel, and an inefficiently won one at that.

I used to have a very dim view of nuclear, and a stint working on the ropes at Sellafield did nothing to challenge that. BNFL appeared very untrustworthy.

But that's BNFL's management, not nuclear per se. I'm all for it in our current circumstances if properly managed.

It had that exact effect here in N.

Exactly.  One the reasons that domestic prices are so high is because Uttilities have to hedge against price fluctuations for imports and err on the side of caution hence we get news stories about paying x for a unit when the spot price is x-y but we the public don't realise that these prices are agreed with suppliers months or years in advance.  Having a stable domestic supply in itself will bring prices down by eliminating the need to buy on the hedged futures market and having the ability to supply a significant volume of domestic gas will bring prices down further because there are no transportation costs involved.  The effect in the US has been very dramatic with companies bringing manufacturing back onshore as well as low prices for consumers.

BP report indicates that shale gas finds will not reduce emissions...

And on price changes

'Meanwhile, analysts at the City firm Brewin Dolphin also poured scorn on Cameron and George Osborne for over-hyping the potential impact of shale in Britain. "We believe the shale industry is unlikely to produce commercial volumes of gas until the end of this decade and that it is unlikely to have a meaningful impact on gas prices," said a report drawn up by Elaine Coverley, head of equity research, and Iain Armstrong, oil and gas equity analyst at the investment house.
"This is due to two reasons; first, commercially available volumes are likely to be significantly lower in the UK than in the US, and second, if UK shale is successful, exploration companies could export the gas to achieve higher prices," they argue.'

Proponents of the fuel have argued that shale gas can counteract dependence on coal. But while shale gas use has increased dramatically, particularly in the US, where it brought down gas prices from $12 (£7) to below $3 (£1.80) at one stage, global emissions have continued to rise as the coal that would otherwise have been used has been exported elsewhere.

So if coal use in the UK declines and shale gas usage increases, then the UK's carbon emissions would drop, everything else being equal.
 
What energy companies do about exporting unused coal, and what other countries do about their own use of coal, does not come under the responsibility of the UK wanting to start using shale gas, and shouldn't factor in the discussion.
That is a separate discussion about where energy companies responsibilities lie, between profit-making and environmental responsibility. The article's point is analogous to saying there's no point in the UK switching to shale gas (which is much cleaner than coal) because other countries are planning on using more coal so the net carbon output won't change. If you believe that then you should also believe there's no point switching to wind/solar/tidal either.

Shale gas might emit less carbon dioxide than coal when burned, but the process of extracting it releases loads of methane into the atmosphere. Maybe in the UK we'll be able to reduce methane leaks but I'm yet to be convinced.

In the short-term:
I believe shale gas is sensible if it replaces coal, perhaps entirely, in the overall UK mix - the total resource and rate of extraction is still uncertain.
Limited tidal and wind - I honestly don't think wind is going to look attractive in 20 years after we get a longer-term idea of how much downtime the turbines suffer and we understand the true cost, and where that money could have been invested instead into other tech. I personally think turbines are part a money-making bandwagon/ part useful resource.
Solar PV and water heating on all new housing and retrofit to existing housing. In combination with better insulation, widespread awareness of fuel use through better metering/thermostats.
Domestic waste power plants like the one next to my office in Runcorn.
Carbon storage (perhaps in combination with shale gas operations?)
Emissions scrubbing retrofitted on all exisitng coal-fired power stations (already in place on most?)
Co-gen to supply more waste heat to domestic and commerical premises.

Mid-term:
Nuclear makes sense to me, especially if someone had the courage to try non-military fuels.
An end to importing fossil fuel - a UN or similar enforced ban.
Better storage technology to make intermittent energy sources more viable.
Versions of today's billionaires like Bill Gates etc. getting into the clean energy sector and shaking things up.


Long term:
Pick whatever you want out of your imagination and combine with whichever economic system you believe will exist - space solar PV, Tesla electricity transmission, Nuclear fusion, moon-based power stations could be as carbon-emitting as it's possible to be - who cares!, fuel cells, Dawes vegetable cars...

There seems to a bit of a generation gap I'd posit at around 40/45. The older have seen various nuclear/ acid rain/ ice age doom-mongers come and go, and have learned to ignore them and carry on. The younger pretty much without exception, seem to have realised global anthropogenic climate change is real and more likely than not catastrophic. My possibly vain hope is that in the next ten years the balance of power in world governments will shift to the latter, and clean energy will become a given and not a political football.

I think the issue with this debate is that it stretches far beyond science and is tied up with people's perceptions (as you say) and government policy.  No government is going to have the minerals to say (for example) 'right we are going all in for micro generation and all new affordable housing will be fitted with PV and we are going to retrofit all council owned properties over the new five years.  Oh by the way this will add 10% to your tax bill but you'll see the returns in cheaper energy.'

The price for new nuclear seems to be £92.50/MWh according to the bbc, whilst a quick google suggests the wholesale prices are approx £60/MWh on our current grid. I'm unsure about how this ties into other possible government funding approaches for these kinds of projects - whether this is 'it' so to speak, or whether there are many other sources of funding for large projects in addition.

If anyone's interested, the prices the government guarantees to large scale renewables projects are in the document on this page; https://www.gov.uk/government/publications/investing-in-renewable-technologies-cfd-contract-terms-and-strike-priceon (https://www.gov.uk/government/publications/investing-in-renewable-technologies-cfd-contract-terms-and-strike-priceon) page 7. The price for new nuclear seems to be £92.50/MWh according to the bbc, whilst a quick google suggests the wholesale prices are approx £60/MWh on our current grid. I'm unsure about how this ties into other possible government funding approaches for these kinds of projects - whether this is 'it' so to speak, or whether there are many other sources of funding for large projects in addition. Anyone know? Also, does anyone know who funds the storage of waste from nuclear and the decommissioning - is it the company who own the plant or the gov?

Not sure if that includes the storage/decommissioning costs...but as a reference, the decommissioning of Dounreay is currently costing between £50-70million per annum....

Barrows, I believe the price includes decommissioning - but is quite a bit above the market rate (ie what the French pay for the same).
I'm sure I don't need to say this, but this is quite normal in the power generation world - it is very difficult to compare future new-build elec prices to whole sale elec prices being produced from facilities >10 years in age - particularly where the bulk of the elec cost is buried in capex rather than the fuel price (as is the case for nukes).

At some point the unit cost will drop/alternatives will increase and this will become viable/economical...

Chemical process turns any plant matter—even trees—into biofuels (http://arstechnica.com/science/2014/01/chemical-process-turns-any-plant-mattereven-treesinto-biofuels/)

Original : http://dx.doi.org/10.1126/science.1246748 (http://dx.doi.org/10.1126/science.1246748)

NB - Its a new chemical technique which doesn't require expensive & concentrated acids and alkali's and is renewable as the required chemical is extracted from plants as a by-product of the process.

There's a discussion thread on Reddit (http://www.reddit.com/r/science/comments/1vrg97/chemical_process_turns_any_plant_mattereven/) which includes contributions from one of the researchers jerljer (lead author on the paper).

Debate on these matters seems to a be a lot less about science and more about proclaiming your gut instinct.

I think the issue with this debate is that it stretches far beyond science and is tied up with people's perceptions (as you say) and government policy.  No government is going to have the minerals to say (for example) 'right we are going all in for micro generation and all new affordable housing will be fitted with PV and we are going to retrofit all council owned properties over the new five years.  Oh by the way this will add 10% to your tax bill but you'll see the returns in cheaper energy.'

PV has limited use in the UK since it does sod all for peak demand.
Wind isn't much better either, since it's equally unreliable.
Tidal is perhaps a little better.
Wave has potential.
Geothermal - not in this country.
That doesn't mean they can't have a role to play, but it means that until we make serious improvements in production or storage*, renewable energies can't be the basis of our generation. I'm of the opinion that the lack of national and global investment in renewables is basically criminal. But that's where we're at right now.

Until we can convince our government(s) to invest properly in renewables, we require investment somewhere else. The latest-gen nuclear has a lot of advantages, particularly with reduced waste, but the government is purchasing an old-tech plant instead. To be fair, we'd need a big push on nuclear to make the lastest-gen stuff pay. But then, maybe that's what we need.

In the meantime we'll increasingly be forced to rely on more risky or harmful extraction methods for non-renewables. The global future is currently one of fracking, tar-sands and oil-shale. I hope the dutch built those dams well...

*Or long distance transmission. A relatively very small patch of essentially empty Saharan desert covered in PV could power Europe, no problems. Except for the massive investment cost, the politics, and the geopolitical vulnerability brought about by the possibility of sabotaging the transmission lines!

Fracking should be embraced and supported as a good source of energy, jobs, investment and so on.

As for the whingeing watermelon twats blocking the road, nothing a bit of cs spray and water cannon won't sort out.

It's not a road. (http://www.manchestereveningnews.co.uk/news/greater-manchester-news/fifty-anti-fracking-protesters-arrested-barton-6707207)

I'm sure the cunts in charge will just abolish the law anyway.  :wank:

Let's just call it eco-mining and celebrate the benefits it will bring to our rural economies.

I love fracking and nukes.

Other changes reversed on Monday included residents being notified on an individual basis of shale gas operations in their area, gas leaks other than methane being recorded and a legal requirement for environmental impact assessments at sites.

This is really not good news, EIA's are relatively cheap and will at least make the fracking companies consider the environment in which they are working in a structured way.

I had hoped it had gone quiet on the fracking front due to the fall in fuel prices.

On Radio 6 earlier the news was implying it wasn't a proper ban, only that they won't grant further licences unless further evidence emerges of the benefits.

The cynic in me feels like the timing of this, with an election looming, isn't a coincidence... Though hopefully I'm wrong!

Oh I think you're absolutely spot on, very much a carefully timed announcement.

Good news regardless.

I saw that the opposition line was the obvious "it's not a proper ban", which to be fair I don't think it is. That said, surely it's an eminently sensible stance to say it won't happen unless clear evidence emerges that it is safe?
