   Wendy Miller
• 1970s: plans for a nuclear power station in area
• 1980s: Chernobyl
• Local response
   – NIMBY
   – Locals did extensive search for alternatives
• 1986 City of Freiburg adopted power supply concept
   – Reduce energy demand
   – Efficient energy technologies (co-generation CHP plants)
   – Renewable energies
• 1996: Freiburg Climate Protection Plan
   – aim to reduce co2 emissions to 25% below 1992 levels by 2010
       From the Lord Mayor
• Model of a future regional development
• City energy policy
  – Abandonment of nuclear energy
  – Cautious use of valuable energy sources
  – Climate protection
• “(Solar projects) are convincing
  demonstrations of the sustainable change
  of industrial society.”
   Freiburg, Germany          Australia

Development of the solar economy
• Multi-faceted: Planning, Financing,
  Installation and Maintenance,
  manufacturing, distribution, retail . . .
• “The large increase in enterprises in the
  solar industry in the region proves that it is
  not only possible to live with the sun, but
  also from the sun.”
