Sustainable energy use: some reflections on the future use of energy

Abstract

It is argued that the common definition of 'sustainable development' is void of meaning. An alternative interpretation is offered. While current supplies of fossil fuels appear to be adequate, the real situation is less reassuring. Increasing global demand, the geographical concentration of the world's remaining supplies to the Gulf region, the difficulties encountered in mobilizing global coal supplies and the prospect of a global carbon–dioxide induced greenhouse warming are discussed. It is furthermore argued that within the foreseeable future neither nuclear nor renewable energy sources can more than marginally replace the fossil fuels on a global level. It is also suggested that demand side management (DSM), i.e. more efficient use of energy, is more likely to increase energy demand than to reduce it. Contrary to common belief DSM is no substitute for increased energy production. However, given proper management, we do have the resources required to arrive at a sustained energy future.
