With the many benefits of biogas, it is starting to become a popular source of energy and is starting to be used in the United States more.<ref>{{Cite web |title=Inflation Reduction Act Gives a Boost to the Biogas Sector |url=https://www.natlawreview.com/article/inflation-reduction-act-gives-boost-to-biogas-sector |access-date=2022-10-19 |website=The National Law Review |language=en}}</ref> In 2003, the United States consumed {{convert|147|e12BTU|TWh|order=flip|abbr=unit}} of energy from "landfill gas", about 0.6% of the total U.S. natural gas consumption.<ref name="What is biogas">[http://www.afdc.energy.gov/afdc/fuels/emerging_biogas_what_is.html What is biogas?], U.S. Department of Energy, 13 April 2010</ref> Methane biogas derived from cow manure is being tested in the U.S. According to a 2008 study, collected by the ''Science and Children'' magazine, methane biogas from cow manure would be sufficient to produce 100 billion [[kilowatt hour]]s enough to power millions of homes across America. Furthermore, methane biogas has been tested to prove that it can reduce 99 million metric tons of greenhouse gas emissions or about 4% of the greenhouse gases produced by the United States.<ref>{{Cite journal|author=Cuellar, Amanda D and Michael E Webber|title=Cow power: the energy and emissions benefits of converting manure to biogas|year=2008 |journal=Environ.

The number of farm-based digesters increased by 21% in 2021 according to the American Biogas Council.<ref>{{Cite news |last=Moran |first=Barbara |date=November 9, 2022 |title=Massachusetts companies are turning to 'anaerobic digesters' to dispose of food waste |language=en |work=NPR News |url=https://www.npr.org/2022/11/09/1135619186/massachusetts-companies-are-turning-to-anaerobic-digesters-to-dispose-of-food-wa#storytext |access-date=2022-11-11}}</ref> In Vermont biogas generated on dairy farms was included in the CVPS Cow Power program. The program was originally offered by Central Vermont Public Service Corporation as a voluntary tariff and now with a recent merger with Green Mountain Power is now the GMP Cow Power Program. Customers can elect to pay a premium on their electric bill, and that premium is passed directly to the farms in the program. In [[Sheldon, Vermont]], Green Mountain Dairy has provided renewable energy as part of the Cow Power program. It started when the brothers who own the farm, Bill and Brian Rowell, wanted to address some of the manure management challenges faced by dairy farms, including manure odor, and nutrient availability for the crops they need to grow to feed the animals. They installed an anaerobic digester to process the cow and milking center waste from their 950 cows to produce renewable energy, a bedding to replace sawdust, and a plant-friendly fertilizer. The energy and environmental attributes are sold to the GMP Cow Power program. On average, the system run by the Rowells produces enough electricity to power 300 to 350 other homes. The generator capacity is about 300 kilowatts.<ref>Zezima, Katie. "[https://www.nytimes.com/2008/09/24/business/businessspecial2/24farmers.html Electricity From What Cows Leave Behind]."

In [[Hereford, Texas]], cow manure is being used to power an [[ethanol fuel|ethanol power]] plant. By switching to methane biogas, the ethanol power plant has saved 1000 barrels of oil a day. Over all, the power plant has reduced transportation costs and will be opening many more jobs for future power plants that will rely on biogas.<ref>State Energy Conservation Office (Texas).

In [[Oakley, Kansas]], an ethanol plant considered to be one of the largest biogas facilities in North America is using [[integrated manure utilization system]] (IMUS) to produce heat for its boilers by utilizing feedlot manure, municipal organics and ethanol plant waste. At full capacity the plant is expected to replace 90% of the fossil fuel used in the manufacturing process of ethanol and methanol.<ref>Trash-to-energy trend boosts anaerobic digesters [http://finance-commerce.com/2013/10/trash-to-energy-trend-boosts-anaerobic-digesters/]."</ref><ref>Western Plains Energy finishing up North America's largest biogas digester [http://www.biofuelsdigest.com/bdigest/2013/03/13/western-plains-energy-finishing-up-north-americas-largest-biogas-digester/]."</ref>

In California, the [[Southern California Gas Company]] has advocated for mixing biogas into existing natural gas pipelines. However, California state officials have taken the position that biogas is "better used in hard-to-electrify sectors of the economy-- like aviation, heavy industry and long-haul trucking".<ref>{{Cite web|url=https://insideclimatenews.org/news/13112019/biogas-climate-change-renewable-gas-marketing-socalgas-reject-electrification-california|title=Fearing for Its Future, a Big Utility Pushes 'Renewable Gas,' Urges Cities to Reject Electrification|last=McKenna|first=Phil|date=2019-11-13|website=InsideClimate News|language=en-US|url-status=dead|archive-url=https://web.archive.org/web/20191116173612/https://insideclimatenews.org/news/13112019/biogas-climate-change-renewable-gas-marketing-socalgas-reject-electrification-california|archive-date=16 November 2019|access-date=2019-11-16}}</ref>
