His claim that wind turbines are useless because they take the effort of 150 tons of coal to produce the steel is interesting. He didn't follow it up with the obvious calculation of how long a wind turbine take a to get that energy back. I did a quick calculation, and it looks like you can recover that input coal energy in only a few months of operation.
