Geothermal greenhouse development update

Greenhouse heating is one of the popular applications of low-to moderated-temperature geothermal resources. Using geothermal energy is both an economical and efficient way to heat greenhouses. Greenhouse heating systems can be designed to utilize low-temperature (>50{degrees}C or 122{degrees}F) resources, which makes the greenhouse an attractive application. These resources are widespread throughout the western states providing a significant potential for expansion of the geothermal greenhouse industry. This article summarizes the development of geothermal heated greenhouses, which mainly began about the mid-1970`s. Based on a survey (Lienau, 1988) conducted in 1988 and updated in 1997, there are 37 operators of commercial greenhouses. Table 1 is a listing of known commercial geothermal greenhouses, we estimate that there may be an additional 25% on which data is not available.
