A new energy regime: possible roles for space technologies and applications

Today\´s global energy mix is dominated by fossil fuels. However, there are clear signs indicating that our current energy regime is not sustainable. The environmental toll of fossil fuels, the related energy security issues and the inherently finite nature of fossil fuels force us to explore new energy sources and technologies. Space technologies and applications can play an important role in using our existing energy resources more efficiently, and in developing new ones. This paper develops the concept of an "energy supply chain" and gives examples of existing and future space technologies and applications that can create innovative solutions for the energy sector. Future research areas are identified and recommendations are given for establishing a more active role for space technologies and applications in the energy sector.
