There are a great many technologies on the horizon that may have great impact on these figures
High temperature super conductors could reduce line losses in electric power transmission increasing effective power output 20%.
It is conceivable that nuclear fusion could become practical in that time frame generating cheap carbon free power (Whoopee).
And there are always new unexpected discoveries popping up. Who knows what might happen.
If we don’t solve the problem energy will become more expensive and demand will be reduced in response and again the problem will solve itself.
But I expect that if government stays out of the way the market will produce adequate power to meet demand. Left to itself the market will produce energy much more abundantly and cheaply than any government agency could imagine.
There's a great idea </sarc> from the article. The piece also suggests that if we generate power from rivers and wind farms, it would solve a large part of this problem. That is, if Ted Kennedy and the greenies ever allow it to happen.
In keeping with the musical sub theme of this thread, it occurs to me that is a good band name: Ted Kennedy and The Greenies. Of course, they would suck.
