Geothermal heat globally
The world looks to geothermal
Geothermal energy is a proven technology globally. In 2009, China was the biggest user of geothermal heat, according to the International Energy Agency (IEA).
In Europe, geothermal district heating systems (GeoDH) are becoming increasingly popular. In 2018, there were was over 5 GW th installed from over 300 systems in operation, with France, Germany and Hungary being the biggest users and an addditional 80 MW th from new countries such as the Netherlands, Belgium and Serbia coming online in 2018 alone (EGEC, 2018). An additional 4GW of GeoDH capacity is due to come on stream by 2019. Geothermal heat has the ability to meet the earth’s energy demands – 4,000 times over. By 2030 nearly all European states will have GeoDH.
The IEA has called on policy makers, local authorities and utilities to be more aware of the geothermal resources available and how they can be used. It calls on them to:
- Introduce economic incentive schemes for geothermal heat and geothermal power
- Introduce streamlined and time-effective procedures for issuing licences for geothermal development.
Achieve global potential
Geothermal heat is ideal for colder countries. However, warmer countries can also use it for agricultural and industrial processes. The IEA predicts that geothermal heat could contribute 5.8 EJ annually by 2050. The largest potential for geothermal heat can be found in Europe, China and North America.
A call to action
For the potential of geothermal energy to be achieved, resolute action is needed. Scientists, governments, industry, financial institutions and the public must act immediately.
