Use of renewables in the US has plummeted

Over at Marginal Revolution:

Percentage of annual net electricity generation by renewables in 1948: 32

Percentage of annual net electricity generation by renewables in 2005: 11

The main difference of course is the fall in the relative import of hydroelectric power.

The book this data comes from sounds interesting. The economics of energy are pretty basic. Low energy prices as at present are an uphill battle for renewables advocates to fight. It’s not possible to run manufacturing plants and heavy industry on solar panels, yet.
