Geysers are used for various activities such as [[electricity]] generation, heating and [[geotourism]]. Many geothermal reserves are found all around the world. The geyser fields in Iceland are some of the most commercially viable geyser locations in the world. Since the 1920s hot water directed from the geysers has been used to heat greenhouses and to grow food that otherwise could not have been cultivated in Iceland's inhospitable climate. Steam and hot water from the geysers has also been used for heating homes since 1943 in Iceland. In 1979 the U.S. Department of Energy (DOE) actively promoted development of geothermal energy in the "Geysers-Calistoga Known Geothermal Resource Area" (KGRA) near [[Calistoga, California]] through a variety of research programs and the Geothermal Loan Guarantee Program.<ref name=OBanion>{{cite journal |last1=O'Banion |first1=K. |last2=Hall |first2=C. |date=14 July 1980 |title=Geothermal energy and the land resource: conflicts and constraints in The Geysers |url=https://digital.library.unt.edu/ark:/67531/metadc1195594/ |journal=Calistoga KGRA |publisher=DOE–SciTech |doi=10.2172/6817678 |osti=6817678 |s2cid=129626036}}</ref> The department is obligated by law to assess the potential environmental impacts of geothermal development.<ref name=OBanion/>
