Sun, wind, water and renewable resources have a growing share in the supply of energy in Germany – meanwhile 10.3 percent. Today, a wide range of technologies and methods are available to produce power, heat or fuel from renewable energies.
They make a decisive contribution to climate protection and security of supply by replacing fossil fuels such as coal, oil, gas or uranium. Moreover, their use causes less environmental problems and considerably contributes to the domestic product. Among the renewable energies, biofuels such as wood and biogas have the greatest share in energy supply. With regard to the generation of electric power, the further extension of the use of wind energy – increasingly produced offshore – is playing an ever more important role.
We face limited potentials in Berlin
The rates at which the use of photovoltaics to produce power and solar thermal energy to produce heat from solar power grow are also remarkable. In Berlin, the potential for using renewable energies is limited as there is fierce competition for space due to the dense settlement structure. Wind turbines can be erected only on large free spaces, the use of geothermal energy is subject to ground water protection regulations and solar power for photovoltaic or solar thermal power plants can be used almost exclusively on roofs.
The Berliner Energieagentur is a driving force for the extended use of renewable energies in Berlin. We always focus on the profitability of the plants. We are operating photovoltaic power plants and bio natural gas fired combined heat and power (CHP) units at our own economic risk. Moreover, we conduct feasibility studies and perform potential analyses in our projects and offer implementation advice on the subject of renewable energies.
