There are six Asian and four European photovoltaic solar energy companies represented in this Top 10.

Regions were selected for the study on account of existing or planned large photovoltaic solar energy or Concentrating Solar Power plants.

Representatives for Korea have signed a Letter of Intent to purchase 2,500 megawatts worth of wind power from Infinity Energy Inc., making it among the largest Wind Farm Plants in the world when complete.

E.ON has unveiled that its Humber Gateway wind energy plant off the East Yorkshire coast, will consist of a 73 wind turbines that will generate up to 219 MW of electricity, enough to wind power up to 170,000 homes.

Siemens Energy has received another large order to build an offshore wind power plant in Germany. For the Amrumbank West wind energy project in the North Sea, the company is supplying 80 wind turbines.

New wind power order for Amrumbank West in North Sea.

China has significantly increased its renewable energy target for solar energy capacity. It also confirmed the existing target to deliver 100 GW of wind energy capacity by 2015.

The $1.2 billion Solar Dawn concentrated solar energy project, which proposes to build a 250 MW solar thermal power facility in Queensland, failed to fund the project.

Ckani wind power envisages the installation of 160, 1.5 MW wind turbines 85m in height. The wind farm will connect to the northern SING power grid via the 220kV El Abra transformer station.

Vestas-American Wind Technology President Martha Wyrsch urged the U.S. Senate to immediately extend the Production Tax Credit that helps owners of wind farm projects afford to build them.

Numbers aside, it?s important to keep the wind energy industry supported while it makes the gains necessary to compete with coal, oil, and natural gas.

The wind energy has modest impacts on birds compared to other forms of energy generation and should be viewed with vastly more significant sources of mortality such as buildings, communication towers, or vehicle.

With a four-year extension, 8,000 to 10,000 MW of new wind farm capacity (enough to power the equivalent of 2 million to 3 million homes) each year through 2016 and an increase in wind turbines supported jobs to 95,000.
