Denmark’s path to a green future…
…It began with the oil crisis in 1973.Policies and external events pushing
development in the use of renewables since 1980

Three actions have been key
- Demand side efficiency measures (insulation of houses etc.)
- Integration of electricity and heating systems improving total efficiency significantly
- Investment in development of wind power and use of biomass/waste

Waste in the national energy system
• Approximately 25% of total waste used in the energy system
• 3,6 mio tons or 38,5 PJ• Used in waste incineration plants and dedicated district
heating plants
• Generating 20 PJ district heat (17% of total demand)• Approximately 2 TWh electricity (6% of total demand)
Waste is a significant part of the energy system

Energy supply from renewable energy by 2050Approaching incentives:
• Ban on installing new oil-fired boilers in new buildings => more renewable energy in buildings
By 2020:• 36 % of bio-energy in energy mix• 50 % wind energy in Danish electricity consumption
By 2035• No use of coal and natural gas in electricity and heat
supplyBy 2050
• Denmark’s entire energy supply covered by renewable energy

Conclusion
• Denmark was severely hit by high oil prices in the 1970’ies
• Continuous emphasis on efficiency, integration of electricity and heat and use of renewables
• District heating an important tool• Today a green energy system • National policy to decrease use of fossil fuels even
