This past March, thousands of people descended on Washington, D.C., to demand that the 99-year-old U.S. Capitol Power Plant stop burning coal to heat and cool the offices of our nation's top legislatures. The Capitol Climate Action organized the event and peacefully shut down the plant for a day, despite an ill-timed snow storm.

They won. On Friday House Speaker Nancy Pelosi (D-Calif.) and Senate Majority Leader Harry Reid (D-Nev.) announced that the plant would stop burning coal and switch over to cleaner natural gas. Natural gas isn't perfect, it's still a fossil fuel that releases CO2 into the air, but it's head and shoulders above dirty, dirty coal as a source for power.

Activism works. We're getting there, slowly but surely.

Just hopefully not too slowly.
