The renewable share of global final energy is larger than the renewable share of global primary energy. This is partly due to traditional
biomass, which consists wholly of final energy consumption. The size of the renewable share of primary energy also depends
on the method used to calculate the primary energy equivalent of the renewable energy sources.
Statistics on final energy consumption usually only show the consumer shares. This diagram shows the breakdown by individual
energy sources and is calculated on the basis of various IEA statistics. The shares shown are merely intended to indicate the relative
scale of the individual components.
Other renewables = geothermal, solar and marine energy

In 2008 one sixth of global demand for final energy was already being satisfied by renewable
energy sources. With a total share of around 12.9 %, biogenic energy sources were the
dominant renewable resource. This large share is due above all to traditional use of biomass.
About 3.3 % is due to hydropower, and the remaining share of 0.4 % is spread among the
other renewable energy technologies.
The development of global final energy consumption follows the trend of primary energy
consumption, which has more than doubled since 1971 (2008: approx. 513,500 PJ). In 2008
alone, global demand for energy increased by 1.9 %, or in absolute figures by 9,390 PJ (for
comparison: AGEB [2] estimates total primary energy consumption in Germany in 2010 at
14,044 PJ). In 2008 the share of global primary energy consumption accounted for by renewables
stood at 12.8 %, the same level as in 2002.
