| After a nearly 20-year upward trend, U.S. CO2 emissions from energy took a sharp and unexpected turn downwards in 2007. By 2013, the country’s annual CO2 emissions had decreased by 11% – a decline not witnessed since the 1979 oil crisis. Experts have generally attributed this decrease to the economic recession, and to a huge surge in cheap natural gas displacing coal in the U.S. energy mix. But those same experts mostly overlooked another key factor: the parallel rise in renewable energy production from sources like wind and solar, which expanded substantially over the same 2007-2013 timeframe. Between 2007 and 2013, wind generated electricity grew almost five-fold to 168 TWh and utility-scale solar from 0.6 TWh to 8.7 TWh. During the same period,... |

| The decline in carbon dioxide emissions in the United States between 2007 and 2013 is actually more complex than previously thought. During that period, carbon dioxide emissions from United States energy use decreased sharply and unexpectedly, after rising for nearly two decades. At the end of the six-year period, U.S. annual carbon dioxide emissions had fallen by 11 percent– a drop the nation hadn’t experienced since the 1979 oil crisis. Experts have typically attributed this decline to two factors: the drop in energy demand during the recession that began in 2007 and the surge in inexpensive natural gas that displaced coal in the energy mix during the same time. However, they missed another critical influence that hastened the decline in emissions just... |
