Facts About Alternative Energy Biography
The renewable portion — which included solar PV, wind power, geothermal power, and power from biomass — accounted for 1.6% of the world’s energy consumption, up slightly from 1.4% in 2010 and coming almost exclusively from developed countries. However, BP includes ethanol and biodiesel under the “Oil” category, and if we make that adjustment the renewable portion rises to 2.1% . If we include hydropower in the renewable category, the renewable share rises to 8% of total consumption. (Note that these numbers do not include conventional biomass burning, which I identified in my book as the “main energy source for cooking for most of the developing world, and the primary source of energy for over 2 billion people.”)
Oil was the largest contributor to our global energy needs at 33% of total consumption, followed by coal (30%), natural gas (24%), hydroelectricity (6%), and nuclear power (5%). Cumulatively, fossil fuels provided 87% of the world’s energy in 2011, which was actually a tiny fraction higher than in 2010 (86.9%). (If we add nuclear power, fossil fuels plus nuclear power provided 92.1% of all energy in 2010, and declined a tiny fraction to 92.0% in 2011 because of a slight decline in nuclear electricity).
