In this paper we discuss the overall balance for Sweden and to some extent EU27 with respect to both power and heat production in relation to how the energy is utilized. This includes transportation, where we compare the system of today with a possible future system with hybrid-electric vehicles, renewable fuels and reductions of total consumption, through both better vehicles, as well as better logistics for transportation of goods. Concerning industry use energy improvements through more efficient industrial processes is discussed. For households, offices and manufacturing industries energy efficient buildings and individual behavior with respect to energy use is discussed. New sources for power will be less stable, like wind and solar power. A special focus is on biomass utilization and production. This also includes food. The situation today is compared to the potential balance after implementation of the actions discussed in the paper. The overall conclusion is that it should be relatively easy for Sweden to reach a sustainable society, if just the political will is present. It is also shown that there is a good potential also for the complete EU 27, but the actions are significantly more demanding to reach the balance, although in no way impossible.
