Ljusdals municipality is a municipality with a low population density and large areal of forest and arable land which offers great amounts of biomass. The aim of this project is to make an energy flow survey of Ljusdals municipality. The reason for this analysis is to discover possibilities to utilize and refine the resources locally. As it is today the raw material is transported to other municipalities for processing and then bought back, e.g. biomass is transported to other municipalities where they make wood pellets, the wood pellets are then sold back to Ljusdals municipality. A local upgrading of the raw material will probably create more job opportunities in the municipality and it will probably also lead to a higher profit than just selling the raw material. The target groups for this survey are the local, and regional, politicians and entrepreneurs, primarily in Ljusdal, but also in other similar municipalities. Mainly bio energy is handled in this thesis. Other energy sources e.g. hydroelectricity is handled just briefly.
