The Council of the District of Columbia voted unanimously on Nov. 27 to advance a bill that would double the renewable energy portfolio standard to 100 percent by 2032, from the current target of 50 percent. The bill, which amends the Renewable Energy Portfolio Standard Act of 2004, would require utilities operating in the District to source all their electricity from renewable energy over the next 15 years, making it one of the fastest transitions in the nation. The bill also mandates utilities to source at least 5 percent of their power from solar by 2032, and to shift public transportation to zero-emission technologies by 2045. City- and state-level renewable mandates have taken on increased importance as the Trump administration has remained skeptical about climate change, gutting federal environmental policies, and as U.S. incentives for wind and solar start to phase out in the coming years. The bill has ample support and is expected to become law by the end of the year.
