I wish I had saved a link to article here a few months ago where some wind power proponents were argueing that new advances in wind turbines had finally made wind power turn the corner and become competitive with conventional power plants. Guess that was more vaporware....
Personally, I think the only serious power that ever got generated from wind is political power.
The Saudis know this and are pumping oil like mad. We delude ourselves into thinking their oil pumping is a favor from an ally-- it is not. It is a means to extract as much cash as possible from a technology soon to be made obsolete by fuel cell technology. Oil has, at most, two more decades to be king. Were the U.S., Japan and the E.C. to fund fuel cell technology with a Manhattan Project-like priority, that time could be cut into 10 years or less.
We've all heard the saying that the next Middle Eastern war will be over water, not oil. It is probably true.
