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
National energy policy 2013-20
Energy supply from renewable
energy by 2050
Approaching 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
supply
By 2050
• Denmark’s entire energy supply covered by renewable
energy
Substantial change in RES share
Substantial change in fuel for
power generation
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
further
