Don't complete write off wind energy--it seems to be becoming
much more economical than it once was. Denmark already gets
13% of its electricity from wind, and plans to increase that
to 50% by 2030. Take a look at www.windpower.dk.


Keep this in perspective. Currently that is less than 2% of Denmark's total
energy use. Denmark's electrical usage is only 1% of the U.S. usage. To
get equivalent percentages of wind use here you need 100x the number of
generators. To use wind for sizable percentages of U.S. energy needs will
require literally millions of fairly large (250-500 kW) generators.
