San Francisco To Phase Out Natural Gas Furnaces, Water Heaters

SAUSALITO, CA - JUNE 20: The Transamerica Pyramid building is seen through the north tower of the Golden Gate Bridge June 20, 2007 as seen from Sausalito, California. Pacific Gas and Electric has launched an estimated $1.5 million research program to study the possibility of submerging turbines under the water to gather energy from tidal flows. A previous study conducted by the Electric Power Research Institute in 2006 came to conclude that the tides that pass under the iconic Golden Gate bridge are the best on the West Coast of the U.S. to generate power.

  • San Francisco Bay air quality regulators have made a landmark move in a national squabble over natural gas-fueled appliances by approving a gradual phaseout of gas-powered water heaters and furnaces.
  • The Bay Area Air Quality Management District (BAAQMD) voted on Wednesday to adopt new rules that seek to eliminate harmful nitrogen oxide (NOx) emissions from these appliances.
  • The rules will ban the sale of NOx-emitting natural gas water heaters in 2027 and prohibit NOx-emitting furnaces in 2029 and large commercial water heaters in 2031.
