In North Carolina, US, Duke University and electric and gas service provider Duke Energy, have developed a renewable energy project with the help of search engine Google. The project creates electricity from pig excrement.
The biogas plant has been set up at the Yadkinville-based Loyd Ray Farms, which is home to 9,000 pigs.
Duke Energy and the university have invested $1.2 million (€880,000 million) in the project to date, however Google's investment has not been divulged.
Originally proposed almost three years ago, the project also received grants from the US Department of Agriculture (USDA) and North Carolina Department of Environment and Natural Resources Lagoon Conversion Program.
The plant will slash CO2 emissions by 5,000 tonnes a year – the same as removing 900 cars from the road.
Both Duke Energy and Duke University will cover the costs of operating and maintaining the plant for the first 10 years that it is online. Google will cover a percentage of the university's costs in return for some of the carbon offsets for a five-year period.
