Plans for the 1-GW Silverton Wind Farm in New South Wales, Australia have been approved and when it’s all done it’ill be the biggest in the country, helping the country to meet its goal of having 20 percent of its electricity come from renewable sources by 2020.

The wind farm will take up 80,000 acres of land in the outback and will generate enough electricity for 430,000 homes. The $2 billion project will be built by German renewable energy company Conergy.

The first stage of construction will begin in early 2010 and will see the installation of 282 turbines, with 598 turbines planned in total. The government of New South Wales says that this project, along with others planned for the area, will eventually prevent six million tonnes of greenhouse gas emissions per year.
