Comparing Costs of Energy Production

Although fuel costs are free for wind and solar, their intensive capital costs, aggravated by the enormous amount of collection facilities that must be built, drive up their lifetime costs. It takes 9,500 windmills, for instance, to equal the life-cycle output of one AP1000 nuclear reactors, which is not the biggest reactor being built. Wind requires ten times the steel, concrete and copper per kWhr than any other energy source.
