<P> The United States Energy Information Administration (EIA) regularly publishes a report on world consumption for most types of primary energy resources . For 2013, estimated world energy consumption was 5.67 × 10 joules, or 157,481 TWh . According to the IEA the total world energy consumption in past years was 143,851 TWh in 2008, 133,602 TWh in 2005, 117,687 TWh in 2000, and 102,569 TWh in 1990 . In 2012 approximately 22% of world energy was consumed in North America, 5% was consumed South and Central America, 23% was consumed in Europe and Eurasia, 3% was consumed in Africa, and 40% was consumed in the Asia Pacific region . </P> <P> The total amount of electricity consumed worldwide was 19,504 TWh in 2013, 16,503 TWh in 2008, 15,105 TWh in 2005, and 12,116 TWh in 2000 . By the end of 2014, the total installed electricity generating capacity worldwide was nearly 6.142 TW (million MW) which only includes generation connected to local electricity grids . In addition there is an unknown amount of heat and electricity consumed off - grid by isolated villages and industries . In 2014, the share of world energy consumption for electricity generation by source was coal at 40.8%, natural gas at 21.6%, nuclear at 10.6%, hydro at 16.4%, other sources (solar, wind, geothermal, biomass, etc .) at 6.3% and oil at 4.3% . Coal and natural gas were the most used energy fuels for generating electricity . The world's electricity consumption was 18,608 TWh in 2012 . This figure is about 18% smaller than the generated electricity, due to grid losses, storage losses, and self - consumption from power plants (gross generation). Cogeneration (CHP) power stations use some of the heat that is otherwise wasted for use in buildings or in industrial processes . </P> <P> In 2016 while total world energy came from 80% fossil fuels, 10% biofuels, 5% nuclear and 5% renewable (hydro, wind, solar, geothermal), only 18% of that total world energy was in the form of electricity . Most of the other 82% was used for heat and transportation . </P> <P> Recently there has been a large increase in international agreements and national Energy Action Plans, such as the EU 2009 Renewable Energy Directive, to increase the use of renewable energy due to the growing concerns about pollution from energy sources that come from fossil fuels such as oil, coal, and natural gas . One such initiative was the United Nations Development Programme's World Energy Assessment in 2000 that highlighted many challenges humanity would have to overcome in order to shift from fossil fuels to renewable energy sources . From 2000--2012 renewable energy grew at a rate higher than any other point in history, with a consumption increase of 176.5 million tonnes of oil . During this period, oil, coal, and natural gas continued to grow and had increases that were much higher than the increase in renewable energy . The following figures illustrate the growth in consumption of fossil fuels such as oil, coal, and natural gas as well as renewable sources of energy during this period . </P>
