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.
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). The report claims that 60% of the cuts came from energy efficiency and a further 40% were the result of a "major structural change in the economy" with estimated savings lying around $800 billion
