In English After the oil crises in the 1970s, the local government in the town of Enköping in Sweden was cautioned by the local Swedish military regiment to shift towards domestic energy supplies rather than imported fossil fuels. During the 1980s the local energy companies investigated opportunities in bioenergy. In the 1990s the local energy companies and local government developed an innovative bioenergy system. The purpose of this paper is to explore the bioenergy system in Enköping as an example of success. This paper begins with definitions for biofuels, biomass, and bioenergy; outlines the methods and research process; describes the development of the bioenergy system in Enköping focusing on biofuel resources, supply systems, conversion technologies, and energy demands; and concludes with findings from the research process.
