Origin of heat
Origin of heat and energy sources
The origin of the heat we sell varies somewhat from year to year. The origin is influenced, for example, by how well our own power plants have produced energy, the price of fuels, and general energy demand.
Our goal is to achieve full carbon neutrality by 2030 in all or part of the energy production we own. Check out our carbon neutrality path.
