"There are simply not enough available forms of alternative energy to replace both of them together. Given a choice between nuclear on the one hand and coal, oil and natural gas on the other, nuclear energy is by far the best option as it emits neither CO2 nor any other air pollutants."
He's right you know. Wind Energy can provide all the Earth's energy but just look at the pollution. {SARCASM ALERT}. OTEC or Ocean Thermo Electric Conversion can also provide pollution free electricity. This guy has an agenda and its not a sound Energy policy!
But imagine how hard it will be to do the environmental impact study to judge the effects of taking that much energy out of our wind currents.
I don't know what percentage of the total available wind power will be taken if we try to get all our energy from wind power, but certainly at SOME point draining energy from the wind would seriously change weather patterns.
