Iceland’s geothermal edge
Iceland’s geothermal systems now supply 27.5% of the country’s overall energy consumption and have been the main source of space heating since 1971 — a backbone for its tourism infrastructure and geothermal spa experiences (web briefing). The March 23 feature frames Iceland as a case study in climate-friendly adventure tourism powered by local geothermal energy (web briefing). (renewableenergymagazine.com)
Iceland’s total installed geothermal electricity capacity was about 788 MW in 2024, according to IRENA data compiled by Our World in Data. (ourworldindata.org) The Hellisheiði geothermal complex is the country’s largest single facility, producing roughly 303 MW of electricity and several hundred MW of thermal output (reported as about 400 MWth by industry sources). (power-technology.com) Nesjavellir, north of Hengill, can supply roughly 120 MW of electricity and up to about 300 MW of hot water to Reykjavík’s district-heating network. (on.is) The Blue Lagoon’s waters are fed from the nearby Svartsengi geothermal power station, and the spa attracts on the order of 700,000 visitors a year — a major single-site draw for Iceland’s tourism sector. (en.wikipedia.org) Nationwide there are more than 120 municipal geothermal pools and public bathing facilities, with 18 public pools within the Reykjavík area alone, a built infrastructure that supports winter tourism and everyday community life. (icelandair.com) Iceland’s swimming-pool culture was inscribed on UNESCO’s Representative List of the Intangible Cultural Heritage of Humanity in December 2025, a recognition that links cultural tourism directly to geothermal heating and public bathing traditions. (reykjavik.is) Geothermal-powered attractions and services are also exposed to natural hazards: the Blue Lagoon and nearby facilities have temporarily closed during episodes of elevated seismicity and volcanic-threat periods in 2023 and after, illustrating operational risks for geothermal-dependent tourism.
