Here’s a quiz; no conferring. To the nearest whole number, what percentage of the world’s energy consumption was supplied by wind power in 2014, the last year for which there are reliable figures? Was it 20 per cent, 10 per cent or 5 per cent? None of the above: it was 0 per cent. That is to say, to the nearest whole number, there is still no wind power on Earth.https://www.spectator.co.uk/2017/05/wind-turbines-are-neither-clean-nor-green-and-they-provide-zero-global-energy/

Electric cars will help destroy the oceans
The future of electric cars may depend on mining critically important metals on the ocean floor.https://www.bbc.com/news/science-environment-49759626
That's the view of the engineer leading a major European investigation into new sources of key elements.
Demand is soaring for the metal cobalt - an essential ingredient in batteries and abundant in rocks on the seabed.
Laurens de Jonge, who's running the EU project, says the transition to electric cars means "we need those resources".

High cost of recycling wind turbines
While the turbines' steel and concrete can be disposed of without greater problems, the UBA found that the rotor blades will pose particular problems as the materials they are made of are difficult to separate properly. By 2024, about 70,000 tonnes of old blades could pile up annually in Germany alone. Moreover, the reserves set aside by operators could fall short of covering the financial needs by hundreds of millions of euros by 2038, which is why the UBA recommends reviewing the reserves' calculation base and have them reviewed by independent experts on a regular basis.https://www.cleanenergywire.org/news/mass-dismantling-old-wind-turbines-could-overburden-germanys-recycling-capacities?
