[QUOTE="dullonien, post: 1099033, member: 13739"] I want to know how much carbon these big wind turbines take to manufacture, ship and install. When I was in uni a lecturer once said that due to their complexity and size + the fact that they're shipped around the world during manufacture + can't generate energy during either high (spin too fast and break themselves apart) or low winds (not enough energy to spin) + extended downtime for maintenance, all meaning that they take a long, long time to even break even. I don't know how accurate that was (it was a lecture on energy use in buildings), or if things have changed, or if it factored in the current surplus of energy currently wasted during high output/low consumption periods (windy nights). They're undoubtedly great for the UK's advertised carbon footprint, but we might be offsetting that carbon somewhere else in the world where they're manufactured. I hope I'm wrong here, because I'm all for capturing the abundance of wind energy we have as an island. I lived a couple of miles from a wind farm growing up and used to go mountain biking around the gravel roads used to service them, and have zero issues about their noise or visual 'polution'. An ideal solution for capturing the waste energy is by generating hydrogen, I believe this would be better than huge battery farms, at least for the time being. [/QUOTE]
