Energy and climate policy targets of the European Union. Central targets for 2020 within the scope of the energy and climate policy strategy: Reduction of greenhouse gas emissions by at least 20 % compared to the level of 1990 (30 %, if other industrialised countries commit to comparable reductions). An increase in the use of renewable energy sources to 20 % of the total energy production. An energy consumption reduction of 20 % through improvements in energy efficiency.

The energy policy targets of the Federal Government (I). The energy concept of the Federal Government formulates guidelines for a complete strategy until the year 2050, describing the path leading to the age of renewable energy sources. Central targets and measures: Source: BMWi 2011
Reduction of greenhouse gas emissions by 40 % up to 2020 and by 80 % up to 2050 (compared to 1990). Reduction of primary energy consumption by 20 % up to 2020 and by 50 % up to 2050 (compare to 2008) and full utilisation of the efficiency potentials in private homes and the public sector. Increase in energy productivity by an average of 2.1 %. Reduction of the heating requirements in buildings (compared to 2008) of 20 % by 2020. Doubling of the energy renovation rate to 2 % to achieve an almost climateneutral building inventory by 2050. EFFICIENCY - OUR FOCUS.

The energy policy targets of the Federal Government (II). Reduction of power consumption by 10 % up to 2020 and by 25 % up to 2050 (compared to 2008). Electric vehicles in Germany: 1 million by 2020, 5 million by 2030. Increase the proportion of renewable energies used in the gross final energy consumption of 18 % by 2020 and 60 % by 2050. Proportion of gross energy consumption provided by renewable energy power generation: at least 35 % by 2020 and 80 % by 2050. Expansion of offshore wind utilisation to 10 GW by 2020 and 25 GW by 2030 and accelerated expansion of the power grid infrastructure (North-South transmission lines). Legislation in 2011: Acceleration of the expansion of the power grid infrastructure. Legislation in 2011: Phasing out of the use of nuclear energy in Germany by 2022. EFFICIENCY - OUR FOCUS.

Power plant sites in Germany >100 MW and wind energy. Existing fossil or nuclear generation capacities are located mainly close to load-centers in western and southern Germany.
RES-expansion (mainly windenergy) leads to a regional shift of generation capacities towards northern Germany. This trend will be intensified by the planned Offshore-WindEnergy expansion.
Existing transmission grids meet their limits particularly on northsouth and east-westlines, when an efficient RES-integration is intended. Source: Umweltbundesamt (UBA) 2012

Energy efficiency must be a fundamental element of the energy turnaround. . Efficiency at all stages of the value-adding chain. Efficient expansion using REG technologies, with harmonization of the expansion planning of the Federal States. Synchronisation of further REG expansion with expansion of the infrastructures and energy storage systems.
