Market Definition
Geothermal energy is renewable energy that is harnessed from the heat inside the Earth. Water and/or steam carry the geothermal energy to the Earth's surface. Depending on its characteristics, geothermal energy can be used for heating and cooling purposes, be harnessed to generate clean electricity, or be used directly for heating. Geothermal electricity generation relies mainly on technologies, such as steam plants, flash plants (single, double, and triple), binary plants, and combined cycle or hybrid plants, that exploit conventional geothermal resources. However, as high-quality conventional resources become harder to access, deeper resources may become accessible in the future through the development of enhanced geothermal systems. Heat energy can also be stored in the ground, such as in borehole energy storage or aquifer energy storage systems, for later retrieval and use. Another major utilization of geothermal heat is its direct use in space heating, aquaculture, horticulture, swimming pools, and spa treatments. Ground source/geothermal heat pumps use the Earth's shallow ground temperature for heating and cooling, whereas direct-use systems produce heat directly from hot water within the Earth.
