Proportion of energy sources in the global power mix from 2005 to 2040
The chart shows that renewable energies will make up the largest share in electric power generation worldwide starting in approximately 2040.
Information and ideas:
In Germany and some other countries, forecasts indicate that the share of renewable energies in electric power generation will increase significantly faster than in the overall consumption of primary energy. For example, in Germany the share in electricity is forecast to be over 65 percent by 2040. Worldwide, however, the forecasts related to electricity and to overall consumption of primary energy (electricity + transportation + heat generation) are both just over 30 percent. How can this difference be explained?
