When you look out over the Langeland countryside, here and there you will see the characteristic windmills and solar power installations. Together they produce more green energy than Langeland can use, in fact we export nearly half of all the energy we produce on the island. Many private households have also invested in green energy, such as ground source heating, wood pellet boilers, solar cells and heat exchangers. More than 4000 households on Langeland are connected to the communal heating system, which is powered by green energy sources such as straw, wood chips and solar power.
