In
Hveravellir 20 km. south of Husavik is a source for
geothermal energy and hydropower. There is extensive
greenhouse
cultivation and a swimming pool. The farm sells fresh vegetables to
travelers from its geothermally heated greenhouses. The
vegetables here are environmentally sound and insecticide free.
From
Hveravellir the geothermal water is piped to Husavik (20 km).
When the
water arrives in Husavik, the temperature is to high
(120°C)
for the central heating system in the town. Therefore the water
must be cooled down to 80°C. In this cooling process
a lot of
energy is released (lost). To utilize this "excess energy",
the
community has built an electrical power plant, located just south of
the inhabited area of Husavik, where
Kalina-technique is used to produce electricity for
the whole town.
