Study on the state of play of energy efficiency of heat and electricity production technologies

This report provides an overview of the current state of the art of the technologies used in EU for power and heat generation as well as combined heat and power generation (cogeneration or CHP). The technologies are categorised per fuel but also in terms of technology selection. The fuels considered are the ones reported in the Strategic European Energy Review report on Energy Sources, Production Costs and Performance of Technologies for Power Generation, Heating and Transport (SEC(2008) 2872).
