Very interesting!
I suspect that you may be aware that wind provides 18 percent of all the power consumed in Denmark and that number is still growing. In Germany which has the weakest winds in europe they produce, I believe, about 4 percent of their power from wind, and they use a lot of power.
Using todays technology we could produce all 3 quads of electricity that this country uses from Texay, N Dakota, and Nebraska. Yes this is equivalent kwhrs but not necessarily as demanded. Still the point is clear that the potential of wind to produce vast amounts of power for less than we pay for gas fired power is there.
