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.

A lot of the transition is attributed to the economy and higher efficiency devices and machines. We have also installed more renewable energy sources, in particular wind power during 2009. Many incentive programs for renewable energies kicked in during 2009.
