Don't expect wind power to replace coal as the nation's main source of electric power, whatever Obama's interior secretary said.
Summary
Interior Secretary Salazar said that the amount of "developable" wind power off the East Coast could produce more energy than all the coal-fired electric plants in the U.S., and that wind's potential to replace most of our coal power "is a very real possibility." We find his claims to be wildly optimistic, to say the least.
It's true that government studies show there's enough offshore wind to generate far more than coal plans currently do – in theory. But converting that wind to enough electricity to replace what's now produced by coal won't happen anytime in the foreseeable future. The Interior Department itself made clear its offshore wind estimate was a gross figure of potential resources only, saying in a report that there are several obstacles to achieving that.
