  1. www.ippnw.de Energy Transition – Energiewende - in Germany

  2. www.ippnw.de The German Energiewende Integrated policy framework which combines four objectives: - Combat climate change - Avoid nuclear risks - Improve energy security - Guarantee competiveness and growth (Source: Agora Energiewende – 12 insights on Germany‘s Energiewende)

  3. www.ippnw.de Wind and Solar -The cheapest renewable energy sources -Weather dependent -Variable -Only capital expenditure

  4. www.ippnw.de Energiewende Wind energy and solar photovoltaics form the backbone of the German Energiewende. - Relatively high capital costs, but no operating costs - Weather dependency, production electricity fluctuates rapidly - Flexibility - the new paradigm of the German power system - These characteristics are fundamentally different from those of coal and natural gas; they profoundly alter the energy system and energy market

  5. www.ippnw.de Challenge: Balance demand and supply - Baseload power plants disappear altogether - Natural gas and coal operate only part time - Operation of combined heat-and-power and biomass plants according to electricity demand - Balance successfulusing national and (not yet) European grids, theyarecheaperthanstoragesystems - Low power generation costs (2015): prices - 6-9 cts€ /kWh for wind energy - 8-9 cts€/kWh for solar PV.

  6. www.ippnw.de Seasonal supply and demand scenarios

  7. www.ippnw.de Renewable energies and electricity demand 2033 (source Agora website)

  8. www.ippnw.de Solutions for flexibility challenge - Wind and PV power need to be expanded in tandem since they have mutually complementary features - The wind blows when the sun is not shining and vice versa - Integrate the heat sector, offers enormous potential for increasing system flexibility

  9. www.ippnw.de Midterm solution combined heat and power plants - in the medium term, dual-mode heating systems, capable of using either fuel or electricity will be deployed; - over the longer term, integration will occur by using a common fuel – natural gas, biogas, or power-to-gas combined

  10. www.ippnw.de Renewable energy –sector overview • 2014 by 2020 Investment in energy plants € 18.8 bn € 235 bn Share of electricity consumption 27.8% 47% Share of heat consumption 9.9% 25% Share of fuel consumption 5.4% 22% Share of final energy consumption 12.3% 28% GHG savings (CO2 eq.) 148 m t2 287 m t (source: renewableenergiesagency, https://www.unendlich-viel-energie.de/)

  11. www.ippnw.de Renewable Energy –sector overview • 2013 by 2020 - Employment – nr. of jobs 371,400 min. 500,000 - Fossil fuelimportssavings€ 9.1 bn € 50 bn - Preventedenvironmental damage € 11.0 bn € 12.3 bn Source: https://www.unendlich-viel-energie.de/

  12. www.ippnw.de Long term state funding:1970 -2014 - Renewables 102 bn Euro - Hard coal 327 bn Euro - Lignite 95 bn Euro - Nuclear 219 bn Euro Renewable energy receives considerably less support than nuclear power, coal, etc. According to IEA data, annual subsidies for fossil fuels alone amounted to around 550 bn $ in 2013 – more than four times the amount for renewables.
