Furthermore the historical financial support for older wind turbines in the USA is time limited. I believe the production tax credit is limited to the first 10 years - thereafter they operate without any subsidy. Yes, and I recently read that many of those end up going out of service due to maintenance costs. There are, reportedly, many fields out of service and abandoned yet still standing.

I should also mention natural gas vents in the ocean which are a potential source and end up in our atmosphere. But, as I said, all safe sources of energy could and should be used.

Jan van Eck + 7,558 MG June 24, 2020 I would be surprised if, inside the USA, anthracite or "hard" coal stops being used. Right now there is this big push, indeed battle, to install a "cap and trade" on carbon credits. Wall Street, specifically Goldman Sachs, just loves this (and pumps money to Democratic legislator candidates to get it passed everywhere) because cap and trade creates a new speculator market, one that Goldman can totally control (now that Lehman Bros. is out of business). Cap-and-trade will force ever higher prices on the carbon credits, a situation ripe for exploitation by Wall Street. Politicians are too stupid to grasp this dynamic. Now what will happen is that heating products, specifically fuel oil in the Northeast, and that includes heating oil [#2 oil], propane, and wood, will get expensive. The old folks on fixed incomes are going to be seriously squeezed. Already in Vermont we have the situation of old folks having to dial down the thermo to 50 degrees during the winter day, and turn it off completely at night [and hope the pipes do not freeze] simply because they cannot afford the tax surcharges on heating fuels. That will get seriously worse with carbon credits. At that point, I will start a bootlegging operation to bring anthracite in from upstate New York, where it is still mined. Hard coal is selling retail for $110/ton, and for another ten bucks they will bag it for you. I will get them to bag it in 20-lb bags so that the old folks can handle them, and then those wood stoves will be singing with coal. I see no other solution to the problem of fighting back against the loonies and the crazies on the Left that are impoverishing old people in their quest to destroy civilization. 1 1 Quote Share this post Link to post Share on other sites

Don't confuse the two. For studies, try the NAS final report and Berkeley Earth, which was set up to by skeptics and ended up confirming what NAS said. Glanced at the NAS report. The findings are far from surprising. Everyone can agree on about one degree since start of industrialisation and 1.5 over 250 years is probably right, so I'm not sure what it was hoping to achieve. The real trick is to extend the time line back to the Medieval Warm period or the Roman Warm period or even the back end of the Holocene and then try to see whether the current warming is unusual or faster than previous changes in climate. There are those who claim that it is but given the huge error bars on proxy measurements (as evident in the NAS report) and the very short period of modern measurements it is difficult to take such claims seriously. Then there is the argument that okay, the earth's climate has been generally cooling on a geological time scale (no argument on that point), however the recent warming attributed to humans in this scenario - goes against that trend. So the change might not be significant but it upsets things, or something.

Given that, the problem it raises is the possibility that we're underestimating the issue, and that we will only know what gets upset only when they happen. Meanwhile, we need to use more fossil fuels anyway because of increasing resource and energy demand worldwide. I think this is the reason why several organizations, from the U.S. military, the DoD, and the Pentagon, to various multinational banks, to companies like Lloyds of London, have been issuing reports to their clients and personnel about what to do given the possible effects of not only global warming but even a resource crunch. 1 Quote Share this post Link to post Share on other sites

I don't know what statistics you are estimating from but I am not saying it is inaccurate. I think that it would require high economic growth in the Third World and a lack of efficiency growth in the way we use energy. I think all that would probably require 30 years. Just my guess. Plenty of time for all sorts of developments, especially in natural gas use unless something better comes along. Or, the remaining population could be living in a dystopian nightmare.

Okay, we can agree on a few things here. Just to be clear I don't endorse Hansen's reasoning at all, and find the carbon in the atmosphere theory so convoluted - this business where the theory has to explain why the miniscule human emissions are significant and why direct measurements show carbon of industrial origin is only a tiny proportion of carbon in the atmosphere - as to be difficult to take seriously. But hey, I'm not a scientist and scientists tell me that the its been confirmed in multiple different ways, so I should get back in my box. However, there is now a clear and compelling case that adaptation is now the way to go and forget attempts to control emissions which basically haven't worked at all. We should be prepared and await developments.. 1 1 Quote Share this post Link to post Share on other sites

I really don't mind wind turbines in flatlands, but when they go on scenic hill crests or near other scenic places it is not a good choice IMHO. Id agree with you on that point. Th progression of the industry to very large turbines makes open flatlands a more viable option than hill crests. Most of the turbine is recycled (the metals). The concrete is left in the ground. The blades can be reused however demand is limited so they can be buried in specific landfill cells - this means they can be dug up later and reused once a reccyling industry is developed. In any case they are inert so they aren't going to pollute the ground. As for the UK - most future build will be offshore and out of site of land. I am not fundamentally opposed to fracking but you need to consider how densely populated the UK is compared to the USA. 2 Quote Share this post Link to post Share on other sites

In the US, the coal, oil, and NG producers are under stringent legal requirements to clean up after themselves and they must post bonds. This has been true for at least 50 years. Most companies "self-bond": i.e., the bond is carried on the companies' books and is not in the hands of a third party. The established long-standing practice is for the asset and the bond to be sold together to a different company in a corporate restructuring when things are about to go down hill. The new company then declares bankruptcy and the taxpayers or landowners are stuck with the problem. Coal mines are fairly obvious, but there are tens of thousands of oil and NG wells have been abandoned without being properly plugged. Some of them have been emitting NG, some with H2S in it, for a hundred years. I would rather have wind turbines: you can at least see those suckers. 1 2 1 Quote Share this post Link to post Share on other sites

Hence the reason for the bond to be held by a third party. The £50K was based on the best of 3 quotes which included removal of all parts except the concrete foundations which were to be recessed back by 600mm and covered in topsoil. The clearance company could sell on the materials. Apart from the visual impact a redundant WT is pretty much inert. Abandoned mines and wells are anything but.

The farms get upgraded instead. This means some of the infrastructure is reused. It is true that some inverters installed in 2010 are at end-of-life in 2020, but some of the replacement is due to upgrades. It's also likely that inverters installed in 2020 will last a lot longer than 10 years because the technology continues to improve. 1 1 Quote Share this post Link to post Share on other sites

I bought a Mastervolt Soladin for £60 to serve the 810W of panels on my east facing roof the other week. The other Soladin I have I bought in 2008 and its serving 660W on the west face. When they go wrong its often the cooling fan which is a £5 replacement. Likewise Ebay awash with second hand panels from solar farm upgrades. I bought 4 270W for £240. On an 810W array I have had 700W which is pretty good at 51 degrees latitude. Payback on DIY solar which a PV immersion diverter is about 17% per annum tax free. Beats the 0.1% my bank is paying on instant access. In fact splitting the area east and west gives the best output across the whole day. 1 1 Quote Share this post Link to post Share on other sites
