Interesting article that really highlights how the fantasy of millions of wind turbines providing 100% of our energy needs is impossible. We don’t have the raw materials to make such a thing and any time steel is made, it must still use coal, a lot of coal. So when discussing alternative power sources, other inputs must be considered.
a 14 MW offshore wind turbine would require 1,300 tons of steel per MW or 18,200 tonnes in total. Such a wind turbine thus consumes 24 times more steel than a coal or gas power plant of the same power capacity.
