6 Explosion of Costs caused by limited Oil Resources Explosion of Costs caused by limited Oil Resources Demand for oil Production of oil world-wide

7 Energy Policy in Freiburg Goals Sustainable Energy Supply Abandoning of nuclear energy Worldwide Climate protection Energy saving Renewable Energy Sources Efficient Technologies * Thermal insulation * Low energy construction * Power saving *Solar energy *Biomass *Hydro-power *Wind-power *Geothermal energy * Power-heat coupling (Co-generation) * Block-type thermal power stations * Long- and shortdistance energy Tallinn1006pptt

8 Freiburg`s Low Energy House (LEH) Standard Demand on LEH: 60 kwh / m 2* a Roof insulation (20 to 30 cm) Heat insulation windows Wall insulation cellar ceiling insulation

9 Sponsoring Program Thermal Protection 2005/2006 Goal: Thermal insulation must be standard at restorations Government subsidies per year Conveying of insulating roof, wall, window, bonus with solar thermal systems Report of the first year: - ca. 90 Applications - 3,7 Mio Prompted investments - ca t CO 2 Savings
