Jutland/Denmark:
• Approx. 50% wind power
• High share of the world’s offshore power
• 30-50% of electricity supplied by CHP
• >50% District Heating
• > 10% Biogas in the natural gas supply
Renewable Energy SystemsA Smart Energy Systems Approach to the Choice and Modeling of 100% Renewable Solutions
1. Edition in 2010
2. Edition in 2014
New Chapter on
Smart Energy
Systems and
Infrastructures
The long-term Objective of Danish Energy Policy
Prime minister 16 November 2008:
”We will free Denmark totally from fossil fuels like oil, coal and gas”
Prime minister 16 November 2008:
”… position Denmark in the heart
of green growth”
Expressed by former Prime Minister Anders FoghRasmussen in his opening speech to the Parliament in 2006 and in several political agreements since then:
To convert to 100% Renewable Energy
100% Renewable Energy 2050…… but how…???!!

Smart Energy Systems
Smart Energy Systems:
Hourly modelling of all smart
grids to identify synergies!
… and influence of different
types of energy storage..!

2019 New Government and agreement:
70% reductions in Greenhouse gases by 2030Climate Law and Action plan:
1. Energy savings in among others public buildings
2. National Strategy for Sustainable buildings
3. Strategy for electrification of transport, industry and society in general
4. More funds for green research and demonstration projects
5. Assessment of Danish and North Sea countries mutual expansion of offshore wind
6. Investigation of energy island of 10 GW wind before 2030
7. Support afforestation (new forest)
8. Climate adoption via coordination of coastal protection
Smart Energy SystemsThe key to cost-efficient 100% Renewable Energy
• A sole focus on renewable electricity (smart grid) production leads to electricity storage and flexible demand solutions!
• Looking at renewable electricity as a part smart energy systems including heating, industry, gas and transportation opens for cheaper and better solutions…
