Greeley is home to North America's largest renewable energy "stomach"

By Kathleen Duff, Greeley Tribune.

Motorists passing by the series of six domed-top tanks and various outbuildings tucked between two dairy farms near LaSalle might dismiss the development as yet another of rural Weld County’s many oil facilities. 

But what those drivers don’t see is an innovative addition to Weld County’s rapidly growing portfolio of renewable energy enterprises. 

Resting on that flat piece of rural land is the Heartland Biogas Project, the largest anaerobic digester in North America. There, food waste and dairy cow manure are converted into renewable natural gas that supplies power to more than 35,000 households.
