Long-term energy solutions

The forest is renewable energy, which grows because of the sun. When you burn bio-fuel it is concentrated solar energy. Your heating has no impact on the greenhouse effect as the amount of carbon dioxide released is the same as the tree has absorbed during its lifetime. As bio-fuel in most cases  grows in Sweden, the cost for production and distribution is only a few percent of the energy content. Effective and environmentally approved equipment from Ariterm gives complete combustion and utilizes the energy value to a maximum. This is also applicable in built-up areas.
