The introduction of the German Renewable Energies Act (EEG) marked the start of the expansion of renewable energies in Germany. The law postulates two fundamental principles: Firstly, in the grid, power from regenerative sources is given priority over conventional power. Secondly, the feed-in tariffs determined by the legislator for the supply of renewable energies establishes investment security for the market actors.
The developments of the past 20 years confirm the success of the EEG: the share of renewable energies in the gross power consumption in Germany has continually increased, from 6.2% in 2000 to 42.1% in 2019. Accordingly, 244 billion kWh are generated from solar energy, wind, water, and biomass. Bioenergy accounts for 11%. In the field of heat generation, renewable energies account for a share of 39%, some 34% of which are based on bioenergy.
