The City of Seattle recently enacted an energy code that will ban natural gas space and water heating in new commercial and large multi-family buildings starting in March. Washington state lawmakers considered a bill that would ban natural gas in all construction projects starting in 2030. And the Oregon Department of Environmental Quality is developing rules as part of Governor Kate Brown’s Cap-and Reduce executive order that could lead to a similar ban on the commercial and residential use of natural gas.  California policymakers are also racing in the same direction.
