Every year several million tons of greenhouse gas emissions could be avoided with renewable energies. In 2008, wind and biomass, hydro and solar energy have avoided a total of 112 million tons CO2.
The use of renewable energy sources instead of crude oil, coal and natural gas is the most important way to achieve the reduction targets for greenhouse gases.
The Renewable Energies Act (EEG), which aims to increase the share of renewable energies in electricity supply, resulted in a saving of 56 million tons of CO2.
If the potential for expansion into electricity, heat and mobility sector is being developed specifically and the required energy in Germany are covered by renewable energies to at least 50% by the year 2050, some 370 million tons of CO2 a year are preventable. This represents around 45% of CO2 emissions, which is currently being caused by the total power generation in Germany.
