Usually when economists talk about efficiencies they means firing people so executives can get better returns, this time efficiency is found by using electricity in smarter ways. The myth that increased energy consumption means a better economy has been “decoupled”. The global economy is using less energy for every dollar produced – a sign that economic progress doesn’t have to mean the destruction of the environment.
The EIA also measured energy productivity, which is the inverse of energy intensity, measuring units of economic productivity for every unit of energy consumed. The world also saw significant increases here over the past two and a half decades. China came out far ahead, with a 133 percent increase in energy productivity between 1990 and 2015, largely due to the fact that increases in economic output were twice that of increases in energy consumption. The US saw a 58 percent gain in energy productivity over the same 25 years as well.
