Renewable energy in Germany – today and future
German-Japanese Wind Energy Symposium Tokyo, 26 February 2013 Harald Neitzel Federal Ministry for Environment, Nature Conservation and Nuclear Safety (BMU) February 2013 1 Introducing Remarks • Germany`s Energy Transition, in particular expansion of RE, under strong considerations; • Transition is running: 1) success factor RE share on electricity market 2012 22 % (2000 6 %); some days about 50 %; 2) progress on heat market and energy saving; 3) stagnation in transport sector; 4) some delays on energy effciency and saving • however: usually only bad news are communicated such as „cost out of control“, „grid expansion fails“, „RE cannot guarantee energy security“ etc. • electricity flows with neighbouring countries: surplus abroad 17 TWh (2012), in NDL, AUT and SUI (2011 only 6 TWh); • at present: several controversial discussions in Germany on how to design next steps, even within Ministries, Parliament, political Parties, business sector, researchers or NGO; • however: strong consensus to proceed on „Energy Transition“ and outstanding role of RE in principle due to several rationales: February 2013 2 German „Energiewende“ 2011 • Strong attention of Fukushima Catastrophie by German public against background of controversial assessments of Nuclear Power since end of 70`ies • Role of Nuclear Energy Policy (bridging technology) was reconsidered and consensus was reached among (almost) all stakeholders to phase out nuclear energy by 2022 (Decisions of 6 June 2011): • previous climate policy programme was enforced, bundle of new measures were included, in particular • Accelerating transformation of energy system, e.g. off-shore wind, grid-extension, energy efficiency February 2013 3 Phasing Out Nuclear Energy Source: UBA February 2013 Resulting from a continuous controversial debate in society and politics since late 70ies (Harrisbury, Green Party, Foundation of BMU after Tschernobyl) 1st Phasing-Out Resolution 2000; however prolongation 2010 by 10 years; “bridging technology” (no consensus) Enhanced discussion after the nuclear disaster in Fukushima: broad consensus to phase out nuclear energy in Germany Seven nuclear power plants were shut down immediately, loss of 8,5 GW firm capacity Remaining nuclear power plants (capacity 11,5 GW) will be shut down in a step-by-step approach until 2022 no problems with grid-stability; ongoing net electricity export to neighbouring countries Historical chance to achieve a fundamental transformation of the energy system 4 The Energiewende: Pillars and Targets Climate 2020 2030 2040 2050 February 2013 Renewable energies Efficiency Greenhouse gases (vs. 1990) Share of elec.

(exaggerated) cost challenges are a short-term issue to be overcome; 4. challenges are well understood and in different stages of action including responsibilities for policy, business, scientific community and civil society; 5. Energy Transition is one of the most important major German post-war „Challenges“. February 2013 18 Thank you for your attention!
