By creating unique landscapes, volcanoes continue to shape Iceland. The earth is boiling beneath our feet and it is not the ideal place to plant a vegetable garden. However, Icelanders manage to grow fruit and vegetables all year round in their huge greenhouses. For example, a farmer in Reykholt (Iceland) produces 600 to 700 tons of tomatoes per year. Thanks to a nearby hot water source, this company's secret is abundant energy. Geothermal energy provides almost free energy for agricultural development, enough to offset high labor and infrastructure costs. Icelandic vegetables find buyers at the stalls, even if they are a bit expensive. Tomatoes, peppers, mushrooms and potatoes are available all year round. Thanks to seven geothermal power plants, almost all of which are public, Iceland is self-sufficient in its energy production. The price of electricity in the country is four to six times cheaper than in France. This renewable, inexhaustible energy is available almost everywhere in the country. Unique properties that inspire the craziest experiments. A greenhouse heated to 20°C thanks to geothermal energy makes it possible to grow bananas. Supported by the government, which aims to improve food independence, the sector is experiencing strong growth. More than 40% of the vegetables consumed by Icelanders were grown in their country.
