Geothermal energy – an untapped renewable energy source with great potential
Geothermal energy comes from the Earth’s interior, and in Denmark, it 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.
12% of Denmark’s current electricity consumption is covered by hydroelectric power.
2% of Denmark’s current electricity consumption is covered by photovoltaics. Solar power is also used for heating, and approximately 1% of Denmark’s district heating comes from 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 500,000 households.
