Consider that all those windmills use large amounts of steel and coal is an essential ingredient in steel production. Ditto coal is essential for making the large amounts of concrete needed for the windmill. Wind turbine blades are made from carbon or glass fibers held together with resins derived from oil. China is also a major manufacturer of solar panels and one of the few sources of rare earth minerals needed for both wind turbines and solar farms. If the US kills its coal and oil industries these raw materials would have to be imported ..most likely from China which has an abysmal record on carbon emissions. So to save a paltry amount of carbon by killing our own economy we will rely on China and other emerging countries like India who will pollute many times more. This is idiocy.
