Today’s energy mix in the United States is radically different from that of a generation ago.
The 2014 edition of the Sustainable Energy in America Factbook – produced for the Business Council for Sustainable Energy by Bloomberg New Energy Finance, provides up-to-date, accurate market intelligence about the broad range of industries — energy efficiency, renewable energy and natural gas — that are contributing to the country's move towards cleaner energy production and more efficient energy usage. Findings from the 2014 Factbook include:
- Natural gas and renewable energy provided over 40 percent of U.S. electricity generation in 2013, down slightly from 2012, but up 10 percent since 2007.
- U.S. energy use has fallen 5 percent from 2007 to 2013, while GDP is estimated to have grown by 6 percent. This demonstrates the increased energy productivity of the U.S. economy.
- Clean energy generation sources and energy efficiency improvements have driven U.S. greenhouse gas emissions down nearly 10 percent since 2005, dramatically reversing decades of increases. The U.S. is now more than halfway to reaching President Obama’s goal of a 17 percent reduction from 2005 levels by 2020.
