Abstract
There are at least 37 greenhouse and 58 aquaculture sites using geothermal energy in the United States. The installed capacity is 119 and 140 MWt respectively. The annual energy use is 1,132 and 3,000 TJ (315 and 833 GWh/yr) respectively. Aquaculture has the largest use of geothermal energy in the U.S. at 35%, and greenhouses amounts toslightly over 13% of the total energy use, if geothermal heat pumps are not considered. These industries have grown 60 and 120% in energy use in the past five years, which amounts to 10 and 17% annual compounded growth. The Geo-Heat Center in Klamath Falls has a technical assistance program to provide advice and preliminary engineering and economic analysis of projects for potential greenhouse and aquaculture developers.The Office of Geothermal and Wind Technologies, U.S. Department of Energy, funds the program.
