Study shows that heat pumps would cut greenhouse gas emissions everywhere if the grid is moderately decarbonized.
Deploying residential heat pumps more widely across the United States has the potential to help reduce carbon pollution while also saving homeowners money, according to a new study by a University of Michigan researcher and colleagues.
