Let's rethink heating
Geothermal energy is an untapped renewable energy source with great potential. Originating from the Earth’s interior, geothermal energy can be used for district heating. Essentially, it entails harnessing subsurface heat – similar to how we harness energy from the sun and wind today – to serve as a sustainable heating alternative to fossil fuels such as coal and gas.
In Denmark, 40% of current electricity consumption is provided by wind turbines.
Worldwide, hydroelectric power is widely used, however in Denmark it plays a minor role – mainly as ‘electricity storage’ at hydroelectric plants in Sweden and Norway. We draw on these stocks when the supply from for example wind turbines or solar cells doesn’t meet our needs. Approximately 10% of Denmark’s current electricity consumption is covered by hydroelectric power.
2% of Denmark’s current electricity consumption as well as 2% of Denmark's district heating is covered by solar power.
Out planet's core is almost as hot as the sun’s surface. With a temperature of around 5,400 degrees Celsius. The heat emitted from the core, radiates towards the surface and is stored in rocks and subterranean water. This warm water is a massive yet unexploited resource that can be used to heat up our homes.
If deployed on a large scale, geothermal energy could potentially provide around 30% of Denmark’s district heating consumption, which corresponds to the heating supply of approximately 600,000 households.
