"The Biden administration has unveiled the first new energy efficiency standards in over 20 years for water heaters in commercial buildings, a move it says could slash greenhouse gas emissions and reduce energy costs.
Proposed yesterday by the Department of Energy, the updated standards would save businesses $140 million per year in operating costs and eliminate certain inefficient natural gas-consuming water heaters from the market, according to DOE.
The new standards would reduce carbon emissions by 38 million metric tons between 2026 and 2055, DOE said — an amount equivalent to the annual emissions of about 37 coal-fired power plants, according to an EPA calculator. Natural gas-powered water heaters typically use about 18 percent of the gas consumed in commercial buildings, the department said, citing data from the U.S. Energy Information Administration."
