Tom Friedman has been in the sun too long.
I assume that everyone reads James Taranto's "Best of the Web" column in the WSJ but just in case you missed it today, he does a wonderful job of deconstructing Mr. Friedman's claim that solar and wind power could be cost effective if only Congress would give them a jump start. Maybe, but only if Congress raises the price of all existing fuels sky high (scroll down to "Gas heads towards $19.84 a gallon") as Taranto proves with quotes from Friedman's own column. So really, Friedman isn't arguing that we can get affordable energy from these alternative sources but rather, if we jack up everything else, they might make the cut. Not an encouraging prospect for a healthy economy, I don't think.

Here's Taranto on Friedman:

Friedman fantasizes about a solution to the energy problem that "will take more than a Manhattan Project":

'It will require a fundamental reshaping by government of the prices and regulations and research-and-development budgets that shape the energy market. Without taxing fossil fuels so they become more expensive and giving subsidies to renewable fuels so they become more competitive--and changing regulations so more people and companies have an interest in energy efficiency--we will not get innovation in clean power at the scale we need.'

Such a massive exercise of government control over the economy is "cost effective" only in the sense that ignorance is strength and slavery is freedom.
