Now in its fifth year, Earth Hour is once again upon us. This Saturday, from 8:30 to 9:30 p.m., people across the globe will turn off their lights, and monuments and homes will briefly stand in darkness to raise awareness about climate change. Washington, D.C., is no exception.

The District has had a tentative history with Earth Hour, participating in the event on a municipal level only. Traditionally it has been lights out at sites like the National Cathedral and Judiciary Square while the monuments, controlled by the Department of the Interior, remain illuminated for safety reasons.

If you’re planning on participating, BlogPost’s Melissa Bell writes about technology invading the worldwide turn-off (flickering candle or flashlight app, anyone?) and the Huffington Post has a photo gallery of world monuments (Washington’s excluded) that participated in last year’s event.

For a dissenting opinion, the Daily Caller points out the “backwardness” of the event.
