Today, 50% of electricity in Denmark is supplied by wind and solar power. Wind energy is well-established in Denmark, which long ago decided to put the Danish climate’s constant breezes and blusters to practical use. Now Denmark produces almost twice as much wind energy per capita as the runner-up among industrialised countries in the OECD. But you may be surprised to hear that wind energy isn’t the most widely used renewable energy source in Denmark. First place actually belongs to bioenergy, followed by wind, solar and geothermal energy. Bioenergy from agriculture More than two-thirds of Denmark’s renewable energy comes from bioenergy, which is energy stored in organic material or biomass. Agriculture is big business in Denmark, and it indirectly helps provide energy too, with manure, animal fats, and straw used as the basis for biogas and liquid biofuels. Many Danish power plants are switching from fossil fuels to biomass (wood pellets, wood chips, or straw). Nearly two-thirds of the Danish households are supplied with district heating (heat networks), where the heat is distributed to citizens as hot water in pipes. Roughly half of the fuel for district heating in Denmark is made up of biomass and other sources of renewable energy. While biomass is a renewable energy source, its climate impact depends on the type of biomass being used. There is a strong focus on securing sustainable biomass in Denmark.
