Key features in electricity and CO2: Europe

► Total electricity output has increased at an annual rate of 1.7% over the last decade, while CO2 emissions have remained relatively stable. The emission intensity has decreased from 0.39 to 0.35 tCO/MWh.

► The largest source of CO2 emissions are coal power plants. Germany, the United Kingdom, Poland and Italy, account for 54% of total European emissions from electricity. Electricity is the main CO2 source in the EU emissions trading system. Power generation generally emits above its allocated CO2 cap and is the main buyer on the carbon market.

► The largest source of electricity is still coal at 27.1% of total output, against 39% in 1990. The European generation mix is characterised by a large share of nuclear (25.1%), and a rapidly increasing share of gas (up 10 percentage points from 1998 to 2008), as well as non-hydro renewables.

► Non-hydro renewables have recorded a spectacular 17.3% per annum growth over the 1998-2008 decade, with their share in total output increasing from 1.9% in 1998 to 6.7% in 2008, thanks to strong policy support measures.

► Wind dominates non-hydro renewable generation with 51.4%. Germany and Spain concentrate a large share of Europe's wind-based electricity with 40.6 TWh in Germany (34% of total European wind power) and 32.2 TWh in Spain (27%). Denmark wind power, 6% of the European total, amounts to 20% of the country's power generation.

► Europe shows a mixed portfolio of technologies for new capacity to be installed post-2010.
