REDUCING GREENHOUSE GAS EMISSIONS AND ELECTRICAL POWER COSTS

摘要

California dairy creates methane recovery system to convert manure into energy that fuels cheese plant and sends excess electricity back into utility grid. IN ATWATER, California, Cottonwood Dairy — operated by Joseph Gallo Farms — will begin operating a biogas-powered generator next month with the capacity to produce up to 2,500,000-kilowatt hours per year from its dairy manure. The new anaerobic digester will save an estimated 275,000 dollar in annual electrical costs, while at the same time reducing greenhouse gas emissions.
