“…These include vegetables, flowers (potted and cut), houseplants, and tree seedlings. As an example, the optimum growth temperature of cucumbers, tomatoes, and lettuce is shown in Figure 1 (Barbier and Fanelli, 1977). Cucumbers grow best in the temperature range 25 to 30 o C, tomatoes near 20 o C, and lettuce at 15 o C and below.…”

“…Optimum temperature is generally more important for aquatic species than land animals, which suggests that the potential of geothermal energy in aquaculture may be greater than in animal husbandry, such as pig and chicken rearing (Barbier and Fanelli, 1977). Figure 2 shows the growth trends for a few land and aquatic species (Beall and Sammels, 1991).…”

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 to slightly 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.

Potential resources and applications of earth heat in the form of geothermal energy are large. World‐wide direct uses amount to 7072 MW thermal above a reference temperature of 35°C. District heating is the major direct use of geothermal energy. Equipment employed in direct use projects is of standard manufacture and includes downhole and circulation pumps, transmission and distribution pipelines, heat exchangers and convectors, heat pumps and chillers. Direct uses of earth heat discussed are district heating and cooling, greenhouse heating and fish farming, process and industrial applications, combined and cascading uses. The economic feasibility of direct use projects is governed by site specific factors such as location of user and resource, resource quality, system load factor and load density, as well as financing. Examples are presented of district heating in Reykjavík, Klamath Falls, Melun l'Amont and Svartsengi. Further developments of direct uses of geothermal energy will depend on matching user needs to the resource, and improving load factors and load density.
