Following June Dairy Month, the American Biogas Council released new figures showing major progress in the expansion of dairy-based biogas systems across the U.S. The Council reports that the number of operational dairy biogas systems has more than doubled since 2020. More than $53 billion has now been invested in renewable energy and methane capture infrastructure.
As of June 2025, 471 dairy biogas systems are online, collectively capturing over 144,000 cubic feet of biogas per minute. That’s enough renewable energy to power about 615,000 homes each year.
These systems not only curb methane emissions and generate energy—they also put to work the manure from roughly 2.3 million cows. That translates into about 15 billion gallons of manure repurposed each year into natural fertilizer, animal bedding, and odor control solutions. According to the Council, the systems eliminate nearly one million tons of methane annually.
Despite the growth, there’s still significant potential ahead: nearly 2,980 dairies nationwide remain eligible for biogas system development.
