To be more specific, energy intensity has fallen from 12.1 thousand Btus per dollar (back in 1980) to 6.1 thousand Btus per dollar (as of 2014), according to the recent analysis. Improvements in energy efficiency have led to energy intensity being cut by a half in the last 35 years according to a recent report from The American Council for an Energy-Efficient Economy (ACEEE). In fact, since 1980, U.S. electricity consumption has been reduced by about 15 percent while overall carbon dioxide emissions have dropped by more than 40 percent.
