High Court Revives Gas Industry Fight Over Biden Efficiency Reg

“The justices ordered a lower bench to take a second look at a challenge against DOE rules for water heaters and furnaces.”

“The Supreme Court has directed a lower court to rethink a ruling that upheld Biden-era efficiency regulations for commercial water heaters and consumer furnaces.

In a short order Monday, the justices directed a federal appeals court in Washington to reconsider its decision “in light of the position” of the Trump administration. In an April brief to the high court, Solicitor General D. John Sauer said the Department of Energy now holds that the rules at issue in the case “rest on a legal error.”

DOE is currently in the process of reviewing efficiency regulations for furnaces and water heaters to determine if they pose an “undue burden” on “domestic energy resources,” Sauer said.”
