Power generation from many types of renewables are 100% efficient in international energy statistics, while fossil power plants achieve only 25–85% efficiency. Though the cost-competitiveness of technologies varies by country, the combined deployment of renewable energy and energy efficiency technologies always results in overall savings.
In the EU, the average efficiency of gas-fired power plants has increased from 34 % in 1990 to 50 % in 2005 and is expected to increase to 54 % by 2015 (Graus and Worrell 2009). For coal-fired power plants, the efficiency, also based on the lower heating value, went up from 34 % in 1990 to 38 % in 2005 and is expected to increase to 40 % by 2015.
In this chapter, the primary technical aspects of conventional and renewable energy systems are presented. The description focuses on commercial systems installed across the world, together with a brief introduction to some promising technologies currently under development, such as Carbon Capture and Storage (CCS).
