The blades of turbines on a wind farm catch the wind 10 August 2007 in front of Aegean Sea on Evia island, off the eastern coast of Greece. Under pressure from the European Union and the terms of the Kyoto Protocol to cut its current reliance on lignite (brown coal) for energy production, Greece has green-lighted several wind farm projects since January. The wind farms are expected to reduce a national energy deficit that currently forces Greece to import electricity from neighbouring countries, mainly Bulgaria and the Former Yugoslav Republic of Macedonia, according to a recent report by the state Regulatory Authority for Energy (RAE).

China has leapfrogged the United States to become the most attractive market for renewable investment this year, says global accounting firm Ernst & Young in a report published in September and is the most attractive market for investment in wind power after Beijing announced plans to launch 90,000 mega-watts of wind capacity by 2015, the report said.

The farm in Melloussa, 34 kms (21 miles) from Tangiers in northern Morocco, has 165 turbines, with a production capacity of 140 megawatts. The project was part-financed by the European Bank, which invested 80 million euros, while Spanish and German banks put in a total of 150 million euros. ABDELHAK SENNA/AFP/Getty Images (credit:Getty)

The world\'s major emerging economies led by China are calling for a \'binding\' amendment to the Kyoto Protocol requiring rich countries to slash carbon pollution by more than 40 percent compared to 1990, according to a document seen by AFP, as Beijing said in November that by 2020 it would curb emissions per unit of gross domestic product by between 40 and 45 percent compared to 2005 levels.

ROCHDALE, UNITED KINGDOM - NOVEMBER 16: The turbine sails of the Scout Moor Wind Farm in the South Pennines dominate the skyline on November 16, 2009 in Rochdale, United Kingdom. As world leaders prepare to gather for the Copenhagen Climate Summit in December, the resolve of the industrial nations seems to be weakening with President Obama stating that it would be impossible to reach a binding deal at the summit. Climate campaigners are concerned that this disappointing announcement is a backward step ahead of the summit. (Photo by Christopher Furlong/Getty Images) (credit:Getty)

PALM SPRINGS, CA - MAY 13: Giant wind turbines are powered by strong prevailing winds on May 13, 2008 near Palm Springs, California. A US government report released this week concludes that wind energy could generate 20 percent of the electricity produced in the US by 2030, as much as is currently provided by nuclear reactors. Although wind energy constitutes only about 1 percent of the electricity of the nation, wind energy is experiencing a growth spurt with an increase of 45 percent jump last year. The report envisions more than 75,000 new wind turbines, many of them bigger than those in use today, and many of them in offshore waters to increase production from the current 16,000 megawatts of power to 300,000 megawatts. The report does not predict that such growth will actually occur but rather that it is possible. (Photo by David McNew/Getty Images) (credit:Getty)
