The first German geothermally heated greenhouse is located in Kirchweidach; it belongs to the Steiner vegetable farm. All heating is supplied by the neighboring geothermal plant. The photovoltaic system on the roof of the operating halls offers a self-contained powered supply. This is how vegetable cultivation can be done regionally and climate-friendly without the use of fossil fuels. Geothermal heat is used to grow tomatoes, peppers and strawberries, reported the German Geothermal Association.
As in Kirchweidach, geothermal energy is already being used in various areas of Europe in a variety of areas. For example, the Hungarian company Árpád-Agrár Ltd uses a geothermal device in their greenhouses. Their main products are spices like pepper and paprika.Best tomato grower in the world
In the Netherlands, the companies Duijvestijn Tomato and Sweet Horst successfully use geothermal energy to grow tomatoes. Cucumbers and strawberries are grown as part of the geothermal project in IJsselmuiden. In 2015, Duijvestijn Tomatoes even won the Best tomato grower in the world award.
