According to the World Energy Outlook 2010 report of the International Energy Agency, the worldwide primary energy demand will be 35% higher in 2035 than in 2008 as a result of increasing world population and increasing prosperity, particularly in the emerging markets. However, on the whole, the proportion of demand for different primary energy sources will change. The study predicts an overall increase in oil consumption of only about 20%, well below the average predicted rise in demand.
Gas, hydro, and other renewable energies will grow in all countries. The share of renewable energies for electricity production will increase from 19% in 2008 to 32% in 2035. But after the Fukushima nuclear disaster in March 2011 and the declaration of a nuclear phase-out by some of the leading industrial nations, it can be assumed that the growth of renewable energies will occur much faster than was predicted in 2010.
