I vote to keep mindmeld.

This was his last previous post post this board:

But make more, Curtis. If you want it on your topic of choice, move it there.

Let's put some numbers to this.
globalis.gvu.unu.edu
US electricity consumption was 3,880,352 Mkwh in 2002.

Using this,
windpower.org
we can expect something like 1.5Mkwh out of a wind turbine. Obviously, this number varies depending on wind steadiness, seasons, wind stength, etc. But it indicates that to satisfy US electricity requirements alone at present levels (and this does not include transportation driven by diesel and gasoline), 2.6 million wind turbines will be needed.

Assuming materials can be found to manufacture them, where will they be put? Favored areas at presents are passes between bodies of water (reservoirs of cold) and inland valleys (reservoirs of heat). Generally, these passes will accomodate a few hundred to maybe at most a few thousand turbines.

They cannot begin to meet the demand.

Better keep looking.

Solar? The same sun that heats that valley and provides the temperature differential needed to produce wind is the sun that produces solar power. Cloudy weather, no wind and no solar power.

Biodiesel might fill in.

But it looks like we've got a real crunch coming if current oil reserve projections are right.
