“Germany can be supplied with 100% renewable electricity by 2050. That is what the German Advisory Council on the Environment (SRU), Prof. Dr. Martin Faulstich, announced May 5, 2010, during the Environmental Commission of the Bundestag. “The federal government should now pave the way for restructuring the energy system.” The SRU has presented various scenarios he prepared to demonstrate that a renewable electricity supply by 2050 exclusively at competitive costs is possible in Germany, with a guaranteed security of supply at any time of year, and a policy of encouraging sustainable innovations. The scenarios are based on estimated models of the German Aerospace Research (DLR). The ReMix model is among the best and most accurate in Europe and works with extremely high temporal resolution.
The main results of the scenarios presented by the SRU are:
– The potential use of renewable energies (RES) in Europe and clearly exceeds largely the need for electric current and also future.
– The considerable fluctuation of wind power and solar development called storage means (close collaboration between the Scandinavian potential – Norway, Sweden – Hydraulics and pumping storage power plant and production capacity in Germany ) and layout of electrical systems (power supply safe, affordable and integrated into a wider connection between Europe and North Africa) to meet demand.
– The cost of falls Electricity in a system based solely on the RES would lower a mix of RES and conventional energy low in CO2. The costs of production, storage and network restructuring could reach 6-7 ct / kWh in 2050, if the policy aimed at a seamless and efficient European interconnection.
– Renewal of the German central park offers favorable conditions for reorganize around the power supply of renewable energy. Thus the conventional power plants currently in operation or under construction should be closed gradually according to their normal life. Under Prof. Dr. Olav Hohmeyer, energy expert of the SRU, for the period of transition or a lengthening of lifetimes of nuclear power plants or manufacture of new coal plants are needed. “The bridge to the era of renewal is already installed”. The SRU is particularly cautioned against over-capacity that extending nuclear activities could lead. Conventional plants would not be consistent over time with power generation, renewable power because they can not adapt quickly enough to changing wind and solar.
– The network expansion and development of methods of storage Germany and Europe is the biggest challenge for a swift transition to renewable era, requiring urgent and effective action.
The scenarios proposed by the SRU are part of a special expertise regarding the future of electricity supply that the SRU intends to publish in autumn 2010. The political demands, legal and economic system transformation in the electric supply only goal of a renewed there will be described in detail.
