President Barack Obama has been claiming that the United States has “doubled our use of renewable energy.” Not true.

Plus, since wind and solar started at such a low level, a doubling may not be as impressive to voters as it sounds.
The largest category of renewable energy is biomass, such as ethanol that is blended in gasoline. And the second-biggest category is hydropower — electricity generated from dams. Hydro was 35 percent of all renewable energy in 2008 and 2011, and biomass dipped a bit to 49 percent for last year.
