  • 1. Renewable Energies and Climate Protection Policy in Freiburg
    • Dr. Dieter Wörner
    • Director,
    • Environmental Protection Agency
    • City of Freiburg - Germany
  • 2.
    • population: 210.000
    • area: 155 km²
    • 42% forest
    • 50% nature or landscape protection
    • „ Environment Capital“
    • „ Solar City“
    • Solar: 1800 hrs sunshine
    • Biomass: forestry and farming
    • Wind: Black Forest hilltops
    • Hydro: river Dreisam
    Facts and figures
  • 3. Climate action concept Objective: climate protection 0 500 1000 1500 2000 2500 Status 1992 Scenario 2010 Energy Traffic Energy + 6% - 25% Traffic and Energy Target 2010 Target: CO 2 -Reduction by Traffic in 1,000 tons CO2 equiv. p.a. Freiburg CO2 emissions Traffic - 5% Energy Interim Statement2003
  • 4. Traffic public transport lines in the Freiburg area: 3,000 km (2003) Fields of action (A)
  • 5. Energy Sustainable Energy Supply cessation of nuclear energy – climate protection Energy saving * Thermal insulation * Low energy construction * Power saving Renewable Energies *Solar energy *Biomass *Hydro-power *Wind-power *Geothermal energy Efficient Technologies * Co-generation of power and heat * CHP * District heating Goals Fields of action (B)
  • 6. Advanced low-energy construction (NEH) Energy saving
    • Max. energy consumption: 60 kWh/m² p.a.
    • Environmental standard as condition of real estate sales contracts
    • Two entire new districts with low energy construction (Rieselfeld and Vauban)
    Roof insulation (20 to 30 cm) Wall insulation basement ceiling insulation Triple glazed windows
  • 7. Co-generation and district heating Efficient technologies Balance 1993 2003 Production of electrictiy ca. 3% ca.52% Nuclear power ca. 60% ca.30% CO 2 -Reduction ca.11% combined heat and power generation
  • 8.
    • Solar energy
    • Biomass
    • Hydropower
    • Wind power
    • Council decision (2004) : 10% electricity from renewables by 2010
    • Currently: 4%
    Renewable energies
  • 9. Solar energy Renewable energies
  • 10. Solar installations in Freiburg status 31.05.2007 PV: 9.05 MW, output p.a.: 8 m kWh solar thermal: 12,411 m² data source: badenova power company Renewable energies EEG = federal renewable energies support
  • 11. Wind power
    • 5 wind mills in total an city area
    • capacity: 5 x 1.8 MW = 15 million kWh p.a.
    • electricity supply: 5000 households
    Renewable energies
  • 12. Biomass
    • Biomass co-generation plant Vauban (6,000 population)
    • Heat and power the entire city district Vauban
    • Fuel: wood-chips (gas for peak production)
    • 7000 kW thermic, 345 kW electric
    Renewable energies
  • 13. Hydro power Renewable energies
  • 14. Electricity from renewable energies Renewable energies
  • 15. „ What is SolarRegion Freiburg ?“
    • Unique accumulation of solar institutions and projects
    • Centre of expertise
    • Network creation as a strategic approach
    • Solar: unique selling position
    • 1st position in „Solar Bundesliga“ contest (2003-2006)
    Success stories
  • 16. Solar economy in the Freiburg Region data 2000 Success stories
  • 17. Instruments: People Participation
    • Citizens as shareholders (investment options, funds)
    • Green tariffs
    • Round tables (administration and citizens' groups)
    • Citizens as technical experts in committees
    • Social marketing, public relations
    • Environmental education (schools projects)
    • Local Agenda 21
    • Aalborg commitments
    Success stories
  • 18. Technical instruments for renewables promotion Success stories
    • Subsidy programmes (by power company, by the City)
    • Funding and financing schemes (e.g., „regional power“ electricity label, innovation funds for climate protection )
    • Urban development programmes (e.g., Vauban, Rieselfeld; sparking off building industry innovation)
    • Energy concepts for all new developments and redevelopments
    • Provision of roofs and other surfaces (PV as second benefit)
  • 19. Structural instruments for renewables promotion
    • Education (schools projects)
    • Research and development (ISE, Solar University, Solar Info Center …)
    • Training (skilled trades, technicians)
    • Technology and knowledge transfer (Italy, Korea …)
    Success stories
  • 20. Political consensus in Freiburg Success stories
    • Economy and environment combine as material benefit
    • Cessation of nuclear energy
    • Strong municipal influence on energy policy (e.g., foundation of badenova power company)
    • Supportive framework for intrinsic motivation rather than push and pull
