Discussions about the future options of the energy systems of industrialised countries are held almost exclusively in terms of alternative resources of energy supply and related technologies. This paper tries to broaden the view of the technological options by focusing on the technical and...

The paper first outlines the challenges the global energy system is facing. It then summarises the present knowledge of energy efficient solutions in all energy using sectors from primary energy to useful energy and, more importantly, from useful energy to energy services (material efficiency...

Ergänzend zu den im ifo Schnelldienst 3/2006 veröffentlichten Beiträgen gehen Eberhard Jochem, ETH Zürich, und Harald Bradke, Fraunhofer Institut für System- und Innovationsforschung, davon aus, dass Versorgungssicherheit durch Ausnutzung von Effizienzpotentialen zu erreichen sei. Ihrer...

Profitable energy-efficiency potentials are often not exploited in industry since management tends not to focus on energy issues. Sharing experiences between companies reveals possibilities for reducing the transaction costs involved. For this purpose, regionally or locally-organised learning...

The People's Republic of China foresees a target of 30 GW for installed wind power capacity by 2010 (2008: 12 GW). This paper reports on the technical and economic potentials of wind power, the recent development, existing obstacles, and related policies in China. The barriers to further...
