Another form of exploitation of geothermal energy is the warming. The largest geothermal system for the warming is in Iceland, in Reykjavik, where all the buildings use geothermal energy for the warming (89% of households). Apart from Iceland as the largest consumer of geothermal energy, countries like New Zealand, Japan, Italy, Philippines and some areas of the United States (San Bernardino, California, Boise, Idaho) also use a large amount of this energy.
Geothermal energy finds its use in agriculture to increase harvest. The water from the geothermal storage is used for warming the greenhouse for the production of flowers and vegetables. It is not only the warming of the air, but also the earth, on which the plants grow. In central Italy, this method is used for centuries. In Hungary, 80% of the greenhouses are concerned by the geothermal energy.
Thermal pumps are another forms in using geothermal energy. They use electrical energy for the diffusion of the geothermal fluid, which is later used for warming, cooling, cooking and preparation of hot water. Therefore, the need for electrical energy is reduced.
Geothermal energy can be used in many ways. Some uses are for breeding the fish, for different types of industrial use, or balneology, the use for recreation and spas.
