The Los Angeles Department of Water and Power will reconsider a $2.2 billion natural gas investment plan, instead signaling that the largest publicly-owned utility in the country will first look to renewable resources to meet demand.

Los Angeles is in the process of overhauling 70% of its generation mix, according to Sierra Club. The decision to "press pause on building gas plants is a sign that the utility is getting serious about eliminating dirty gas from the energy mix," the group said in a statement.
