Wind output reaches new low..
You have to love all that diversity ('the wind is always blowing
somewhere'), in the equinoctial windiness of March, today the metered wind output (23MW) dipped below 1% of 'metered capacity' and looks to stay that way all day. It's nice to know that that capacity that 'could supply up to (insert own bull**** value here) millions of homes' (in themselves not where the largest consumption of electricity takes place) is in fact barely capable of driving 10,000 electric kettles to make a morning cuppa. Or about 4 electric locomotives of decent power output. (http://www.bmreports.com/bsp/bsp_home.htm) It is, in fact, to put it in perspective, about 1/50th of the nice nuclear energy currently being imported from France.. You can always rely on windmills to ....completely fail to deliver, randomly. |

I thought you said something about wind power failing to deliver electricity but I am not sure what. Now you say German Wind power hasn't produced a 'carbon reduction' . Not sure what that means. Wind power hasn't delivered carbon emission reduction. Certainly nothing like 7% of Germany's CO2 attributable to electrical generation. I can't say clearer than that. Also that the German Govt's own figures for electricity consumption and generation are wrong. No, you simply 'misquoted' them. 7% of electricity generation NOT 7% of 'Germanys energy'. Dont worry, most of the wind lobby has trouble dsistuingusighing between electrical power and total energy requirements and none have a clue about exported carbon footprints to e.g. China in terms of energy used to make stuff there we use here..or a clue about what load average means or when 'could power X homes' meas 'will on average power 30% of X homes the home being about one sixth of the power we use altogether, with transport, industry and so on making up the other 5/6ths), and sometimes won't power anything at all) Actually: Wind farms can produce substantial amounts of electricity and do so in Germany. So they can! Mostly, however, they don't. Wind farms do not release CO2 into the atmosphere for every kWh produced so if the alternative is combustion of fossil fuels they represent a big saving in carbon emmissions. Its incontrovertible. Try to fudge it how you will. Sorry, the facts don't bear that out. If the *extra* fuel you have to burn to compensate for the wind output going up and down loses all the advantages the wind seemingly has, you end up with an net zero change in carbon emissions. The point being that the more wind you have - as against nuclear or hydro - the more fossil fuel stations you need to balance it. Having to bring - say - 20GW of fossil online in a hurry when the wind drops overnight, and not necessarily very good fossil either, since its not used fully, so there is little incentive to make it efficient, costs you a huge amount of fuel JUST TO GET IT UP AND RUNNING. As near as I can judge over 75% of winds 'zero carbon' gains are lost to that process. That's the trouble with simple pictures. The world is not simple. Germany remains one of the highest CO2 emitters in Europe with respect to electrical power generation. DESPITE all this so call low carbon wind. Denmark is similar. The real stars of Europe are France and Switzerland, both hugely nuclear and in Switzerland's case, with abundant hydro as well to cover short term demand fluctuations. If you want to permanently get rid of fossil fuel usage, nuclear for the base load and hydro for the demand fluctuations is the way. Wind is completely useless. A grid that had - say - 30% wind and no nuclear or hydro at all would at times have no fossil in use at all, but on average would need *70% fossil to balance it*. Now if we say that without wind, a good CCGT can do say 60% thermal efficency IF FULLY WARMED UP AND LEFT RUNNING, then your carbon fuel rate is 1/60% = 1.667 times grid power If the use of that fossil fuel plant drops to 70% due to adding 30% wind, you still cant get rid of it. You are just using it on average 70% of the time. Let's say its efficiency running like that is is X, so that the fuel burn is then 0.7/X the grid power. And calculate when it's no better than the kit running without any wind. its when 1/0.6=0.7/X which makes the critical value of X = 42%. SO *if the net result of adding 30% average wind to the grid is to reduce the CCGT efficiency from 60% to 42%*, there is *no net emissions gain from wind whatsoever*. A CCGT set running before the secondary cycle gets going, is simply a 37% OCGT gas turbine..every time you start that CCGT set up, it takes fuel to warm it up. Energy that you lose when you switch it off and it cools down. If you add more than 30% wind to the grid, there will be times when you have to throw it away as well, because peak output will mean you have more than you need when the wind DOES blow. You MIGHT put it in pumped storage, at 75% efficiency losing 25% of the value..if you HAD any pumped storage capacity.. We don't really have much, neither does Germany... So at best, 30% windpower on the grid (more is unlikely to actually achieve much more because you start to throw it away)might reduce carbon emissions from electricity generation by perhaps 20%. At best. Maybe 5-10% is likely. 20% nuclear on the grid that totally replaces fossil, could net you a real 20% decrease in fossil fuel usage for electricity.At one fifth the cost. 80% Nuclear - as France has - reduces fossil usage by 80%. The optimal UK mix would be something like 80% nuclear and 20% fast start CCGT. If you really want low carbon electricity. If we had a bit more hydro, we could do a bit better. Sadly geography doesn't favour us there. Dumping our total coal stations could net us something like 70-80% CO2 reduction. No amount of wind can ever produce anything like that sort of emissions reduction. It is simply a complete waste of time and money. It's only there because the Greens run Germany, and the Greens hate nuclear power, and Germany runs the EU. And the windpower companies are..German. Or Danish - Denmark being a sort of lump on the end of Germany for all intents and purposes. |

Yes the figure is for electricity, if that wasn't clear from the context then that was careless of me. No, now you misquote, it is 7% of consumption, not generation.

As near as I can judge over 75% of winds 'zero carbon' gains are lost to that process. That's the trouble with simple pictures. The world is not simple. You imply that wind power will cause problems with variable supply and demand. This is disingenuous because the industry already has to deal with the variations in supply and demand, day, night, weekend, half time on Match of the Day etc.. Yes wind power needs to be part of a mixed industry. We know that. Germany remains one of the highest CO2 emitters in Europe with respect to electrical power generation. DESPITE all this so call low carbon wind. This is disingenuous. Germany is one of the highest emitters because it is the largest economy and one of the biggest populations. Denmark is similar.

It is simply a complete waste of time and money. It's only there because the Greens run Germany, and the Greens hate nuclear power, and Germany runs the EU. And the windpower companies are..German.

Only if wind is economic, which it is on some occasions. e.g. we used a wind generator rather than pay for 10km of powerline to the main grid. Here in NZ wind can be a good idea. We have vast hydroelectric power capability, with not enough rainfall to keep them running all the time. The power from wind generators means the power from hydro generators can be reduced quickly, saving the water in the large dams. Not an option in the UK I agree, but wind power can be economic in some places so let's not rubbish it completely. Also, we should give newer technology a chance to catch up. Wnd and solar power are getting more efficient, and will become cheaper with economies of scale. Wind generators can be supplied and installed quickly and generating power, while your large nuclear and other generators take years to build, with no income until they are finished years later. Then there are transmission losses. The power from wind generators can be used locally, while everybody wants nuclear power stations and coal burning stations to be as far away as possible, hence high power transmission losses and expensive lines. |

I believe Germany does import large amounts of gas for instance from Russia, maybe its imports equate to 2/3 of its energy needs, but I am pretty sure it doesn't import electricity on that scale. In fact the high levels of imports of energy in fuel form must be to serve the power stations. You google the figures. I have to go and do some work.

Yes, they have an 'installed capacity' of about 26GW, which relates to an average grid demand of about 72GW It produces, *on average*, about 5GW. so a typical load average of about 20%, reflecting the fact that its onshore wind by and large. An appallingly crap figure. By my estimation *at best* it displaces 2.5GW of fossil fuel. So a couple of medium (1.25GW) nuclear power stations only. When Sizewell C comes online, (1.6GW) it will, together with Sizewell B, (1.2GW) represent about 3 times the total installed UK wind power in terms of average power generated, and probably save 6 times as much fossil fuel. Two nuclear reactors could easily have done Germany's fossil fuel usage far more good than all the wind, and at a fraction of the cost. Tim W |

I bet they didn't, how much carbon does that mean they produce over their life then? well lets just say that that 7% of windpower on the grid has not markedly changed carbon emissions in electrical power. It (Germany) stands at 1351. The UK is 1228 France (largely nuclear) is 193 Switzerland - hydro and nuclear, is just 11 (Source: http://carma.org/region/detail/185 et al). In short Germany adds wind and switches off nuclear, and sees no reduction in CO2. And has to add gas plant to balance the wind. |

German Wind farms produced about 7% of the energy consumed in Germany in 2009. That is a heck of a significant delivery. Yes but the Germans (i) legislated to make people pay for it earlier and (ii) benefit from the ability to share with other countries through trans-national connection schemes so there is a better chance of the wind blowing somewhere at a time people want to use electricity. (We of course will have to pay through the nose for undersea connections; and probably pay yet more because the EU is involved.) -- Robin PM may be sent to rbw0{at}hotmail{dot}com |
