Editing Geothermal power in Iceland (section)

=== Direct applications ===
Most geothermal energy in Iceland is used for heating activities.<ref name=":62" /> As of 2020, the primary use of geothermal heat is space heating {{convert|23,094|TJ|GWh}}), followed by heated swimming pools {{convert|3,628|TJ|GWh}}), snow melting {{convert|2,036|TJ|GWh}}, fish farming {{convert|1,404|TJ|GWh}}, greenhouses {{convert|429|TJ|GWh}}, and industry usage {{convert|393|TJ|GWh}}.<ref>{{Cite web |date=2020-12-01 |title=Final Heat Use in Iceland 2019 by District Heating Area |url=https://orkustofnun.is/gogn/Talnaefni/OS-2020-T010-01.pdf |website=Orkustofnun}}</ref> As these uses are reliant solely on geothermal heat, they do not result in the energy losses that come with generating electricity. Instead, many of these direct applications use water as the means of transmission. In Iceland's capital [[Reykjavík]], hot water from 100° to 300°C is used to heat homes, then piped into plastic tubing underneath streets and sidewalks at {{cvt|30|C}} to melt snow and ice.<ref>{{Cite web |date=2013-12-11 |title=Heated sidewalks: Iceland has them, Saskatoon wants them |url=https://www.cbc.ca/news/canada/saskatoon/heated-sidewalks-iceland-has-them-saskatoon-wants-them-1.2459674 |access-date=|website=CBC News}}</ref>[[File:Iceland electricity production.svg|thumb|Iceland electricity production by source]]
