The largest U.S. electric holding company, Duke Energy, in March made its first notable commitment to producing power using biogas.
Duke's deal with developer Carbon Cycle Energy could generate up to 125,000 megawatt-hours of energy using methane gas captured from swine and poultry manure sourced in North Carolina. That’s roughly enough electricity to power about 10,000 homes.
"The gas from this project will generate carbon-neutral electricity compared to the emissions that would result if the waste was left to decay naturally," said David Fountain, the Duke Energy executive behind the 15-year-long partnership.
