World energy increased by ten times from 1930 to 2005
The world increased energy usage by ten times from 1930 (50 exajoules) to 2005 (500 exajoules). In 1995-2010, about 90% of the world energy was from coal, oil, natural gas and biofuel (mainly wood, ethanol and sugar cane).In 2012, total world energy consumption was 553 exajoules (553×10^18 J=153,611 TWh), equivalent to an average power consumption of 17.54 TW (or 0.724 on Sagan's Kardashev scale). Two civilizations could have the same energy usage on the Kardeshev scale (say 0.75) b...
