100% energy supply by renewable energy sources: A German case study Andreas Gursch Director Environmental Science & Technology European Chamber of Commerce Taipei
High dependence on imports
Energy mix in Germany
Legislation as initiator
BMU – KI III 1 Version: Renewable energy sources in Germany
Renewable energy act (EEG) Federal law (further development of the Power Feed-In Law of 1991) Priority for feed-in of RE Extensive regulation for grid access legally regulated payment rates –Long-term perspective and investment security (15–30 years) –Incentive for the opening up of new potentials and technologies (esp. biomass and geothermal energy) –Strong incentive for efficiency boost, by degression of payment rates Cost for consumer
Power generation decentralized
Situation in Germany
