Google Inc. is investing in a project that turns hog manure into electricity.
Duke University and Duke Energy (NYSE:DUK) have built a plant that captures methane gas frrm a hog operation in North Carolina and burns enough of it to power 35 homes a year.
The university says Google is covering some of the costs in exchange for a share of the project's carbon offset credits for reducing greenhouse gas emissions.
The Internet giant (Nasdaq:GOOG) is working ot make its operations carbon-neutral, and invests in a variety of projects to offset its emissions.
Open lagoons full of hog waste are a major source of methane gas, which — pound for pound — is 21 times more potent than carbon dioxide as a greenhouse gas.
The university says in a statement its system prevents the equivalent of 5,000 metric tonnes of greenhouse gases from entering the atmosphere every year — the same as taking 900 cars off the road.
