The aim of my research is to study energy systems in the perspective of the society. Energy systems are defined as the supply of electricity and heat at municipal, regional and national levels. Negative effects are for instance a degraded environment and damages on health and materials due to pollution in the air and water.
Positive effects are increased employment and a decreased dependence of imported fuels.
The studies focus on what happens in an energy system regarding system cost, technical solutions and the amounts of CO2, NOx and SOx when external effects are included in the decision process. In order to achieve this there has to be some kind of valuation of externalities. During recent years a couple of studies that examines the values of external effects due to energy conversion has been published. Studies have showed that externa effetcs can have a large impact on the surrondings and on our self. The impact we have on nature will affect u, sooner or later, and we will be forced to pay for this impact.
