Italian energy companies Enel and Edison have signed accords with Italy’s Environment Ministry to raise renewable energy capacity and cut carbon dioxide emissions as part of the country’s efforts to fight climate change, writes Reuters.

Enel has agreed to install 4,100MW of renewable power by 2020 to 2,597MW, excluding big hydro power stations, at the end of 2008.

The company also plans to raise its installed renewable power capacity to 6,700MW by the end of 2009.

The company would reduce annual CO2 emissions by 2 million tons once it completes the conversion of its Porto Tolle thermal power plant to “clean coal” technology.

Edison said that it would cut annual CO2 emissions by 1 million tons, or 10%, by 2014 and raise efficiency of its existing power plants and develop new renewable energy plants with a total capacity of some 400MW.

The company also announced plans to revamp its hydro power plants and install 356MW of wind power plants, 22MW solar plants and 31MW new mini-hydro stations.
