GM isn't actually building any wind new turbines. Not to be skeptical, but that isn't how this clean energy thing works. Rather, GM signed a power supply deal with EDP Renewables North America who has 261 massive wind turbines operating in Texas. Fifteen of them will be sort of designated for GM and the power they create will "save" 1 million metric tons of CO2 form being produced during the production of 125K vehicles per year. GM can now claim that some of its full-sized SUVs are "Build using clean energy." Even better, GM says that its agreement will save the company $2.8 million in energy costs each year.
