Transcript of Energiewende
3. Produce and use fossil energy as efficient as possible
Energy consumption in the transport sector: down 40%
2. Use of renewables energies
1. Reduce energy consumption
Energy consumption in buildings by 2050: down 80%
Overall reduction: down 25%
From 12% to 60%
Development of the global energy use
Efforts to reduce energy dependency
Development of renewable energies
No homogenous distribution of fossil fuel reserves
Dependent on oil and gas imports
Own coal reserves
Development of the global primary energy use
1970er Energy crisis
1973 oil crisis: Organization of Arab Petroleum Exporting Countries proclaimed an oil embargo
1979/80 uncertainties in Middle East after the war between Iran and Iraq.
-> Dramatic increase in oil price
Indebtedness of the government and companies: Unemployment, insolvencies
Consequences for the energy sector in Germany
Raising awareness of dependency on fossil fuel imports
Search for alternatives
Development of nuclear power stations
Development of new drive technologies and fuels
Oil and gas production in the North Sea
Main policy instruments today:
Renewable Energy Law (EEG)
Renewable Energy Heat Act (EEWärmeG)
Market Incentive Programme (MAP)
Promotion of R&D
Foundation January 1980
focus on environmental policy
1983 first entry into the Bundestag
1998-2005: joined government
Wide social consent in the population in favor of the "Energiewende"
Germany is a pioneer in the transformation of the energy system and promoting renewable energies
Oil crisis - dependency
Risk of nuclear disasters
Pathway of energy transition in Germany
Nuclear power in Germany
Nuclear power stations
Myth: The Energiewende is driving up German grid power prices.
Fact: The main contributor of the increase in grid prices are the taxes exemptions for German companies.
Challenge: The German Renewable Energy Act will need further refinement to take into account generation from wind and photovoltaic power plants.
Myth: Large amounts of renewable power are putting Germany's grid at risk of blackouts.
Fact: Grid interruptions fell steadily since records started being kept in 2006.
Germany's grid had just 15 minutes of unplanned interruptions in 2011.
Challenge: The increase of renewable in the German grid is actually a problem of synchronization and planning.
Success of renewable energies

in the RE sector (2012)
Willingness to pay
Dr. Grieger & Cie. market research, 2013:
survey of 1,000 German households
30% would pay more for electricity without nuclear power, 3.11 billion €/y
30% would pay more for electricity if it is only from RE, 3.8 billion €/y
Preference for renewable energies
Are these goals achievable?
Does this make sense?
