It is suggested in this paper that radical reduction in energy consumption is a precondition for reaching a sustainable development. This is the case, also in a country like Norway blessed with energy resources, for environmental, economic, and moral reasons. First is presented an overview of the Norwegian options for saving electricity by changing technology as well as behaviour and structure of the economy. New indicators of progress are suggested and recent trends in people´s preferences towards economic saturation are presented. On this background it is suggested how research within technology, sociology, psychology as well as economy should be redirected.
