A Bloomberg New Energy Finance report shows that U.S. carbon dioxide emission levels are at the lowest since 1994. The drop in emissions was helped by the renewable energy capacity in the U.S. nearly doubling from 2009 to 2012.
The report states the cumulative installed solar, wind, geothermal and biomass based energy sources reached 85.7 GW in 2012. In 2009, the U.S. had 43.5 GW of capacity from the same sources.
Carbon emissions have fallen by 13 percent from a high of 6.02 gigatons in 2007, according to the report. In addition, U.S. energy consumption fell 6.4 percent from 2007 to 2012 as more energy efficient builds were constructed and older, less efficient buildings were retrofitted with new technology.
