The “Scenarios on key drivers” investigate alternative energy futures as distinct from the baseline development that shows the effects of current trends and policies.1 The key drivers concern either different framework conditions for energy and transport policies, such as higher world energy prices, higher or lower economic growth, or they are about different policy approaches on e.g. energy efficiency, renewables, nuclear,modal split in transport and climate change. This publication deals in 9 chapters with these different framework conditions and policy approaches. The analysis covers the European Union of 25 Member states and extends to the year 2030, although in the case of renewable energy, energy efficiency and transport modal shift the analysis focuses
on the impact of alternative policies that could be implemented up to 2010.The scenario results were derived with the PRIMES model that was operated for all 25 Member states of the EU by the National Technical University of Athens.
