Sustainable use of geothermal energy in Icelandic horticulture
The greenhouse industry in Iceland is based on abundant geothermal energy in form of steam or hot water. The annual use of geothermal energy in greenhouses is approx. 216 GWh/yr that accounts for 80 % of the geothermal and hydroelectric energy used in horticulture. Other uses of geothermal energy ar...
