The process of harnessing geothermal energy begins when Icelandic power plants drill more than 1.5 miles down into the Earth to reach the geothermal water table. Once they reach the hot water, steam is generated, which is then brought to the surface. This steam is used to spin turbines at the power plant, generating electricity.
In addition to electricity production, the steam is also channeled through insulated pipes to provide central heating for Icelandic homes. The insulation helps retain the heat as it travels through the pipes, ensuring minimal energy loss. Thanks to this system, geothermal energy provides around 90% of the country’s central heating needs.
