"Today, the final energy use consists of 20 electricity and 80 fuels and heat. The electricity is produced globally by two-thirds from fossil sources. Fuels and heat are to a much larger extend based on fossil sources, say up to 90. In the EU, where we now see a stable energy use, energy efficiency improvement could lead to a reduction of the energy consumption. On a global scale the situation would be different. Because of the much stronger increase in population and economic growth, energy efficiency improvement could still lead to a stabilisation of global energy use.
