global: projection of energy intensity

An increase in economic activity and a growing population does not necessarily have to result in an equivalent increase in energy demand. There is still a large potential for exploiting energy efficiency measures. Under the Reference scenario we assume that energy intensity will be reduced by 1.7% on average per year, leading to a reduction in final energy demand per unit of GDP of about 50% between 2009 and 2050. Under the Energy [R]evolution scenario it is assumed that active policy and technical support for energy efficiency measures will lead to an even higher reduction in energy intensity of almost 70% untill 2050.
