His new plan to get the USA onto a totally “green” power regime would cost trillions of dollars and the resulting power would be intermittant at best since the wind doesn’t always blow and the sun actually sets on the entire country for at least part of the day.

Just moving all vehicles to green electric would cost on the order of 3.5 trillion US dollars worth of wind turbines and batteries. And that doesn’t count in the cost of replacing all other forms of electrical generation, about 760 gigawatts worth. A quick calculation on a table napkin would bring the total to somewhere on the order of 10 trillion US dollars. The Apollo program cost a few orders of magnitude less than that. Plus the whole country would have to be covered with wind turbines, since most of the turbines put out a paltry 1.5 megawatts of power. Thats over 50,000 turbines. The environmental consequences could be staggering.

Funny, some have argued that New Deal policies actually prolonged the Depression. It could be argued that a natural event – the end of the great drought that lasted throughout the Thirties is what really helped end the Depression.

http://drought.unl.edu/whatis/dustbowl.htm – The 1930s drought and its associated impacts finally began to abate during spring 1938. By 1941, most areas of the country were receiving near-normal rainfalls. These rains, along with the outbreak of World War II, alleviated many of the domestic economic problems associated with the 1930s. In fact, the new production demands and positive climatic conditions brought the United States into a rapid economic boom.
