U.S. Energy Use Declines, Renewables Increase

A new government study shows that Americans are using less energy overall and making more use of renewable energy resources.

The United States used significantly less coal and petroleum in 2009 than in 2008, and significantly more wind power. There also was a decline in natural gas use and increases in solar, hydro and geothermal power according to the most recent energy flow charts released by the Lawrence Livermore National Laboratory.
