Cities across the world will dim their lights  tomorrow night—temporarily darkening major landmarks such as the Golden Gate Bridge, Sydney’s Opera House and Chicago's Wrigley Field—in an effort to raise awareness about energy conservation and climate change. Phoenix, Atlanta, and a dozen other US cities will join in for Earth Hour at 8 p.m. local, reports the Christian Science Monitor.

Some critics dismiss the effort as a feeble strategy. “Household light use just isn't a large component of total electricity use," said one, pointing out that when half of Sydney’s residents turned off their lights last year, electricity use dropped only 2%. But a World Wildlife Fund spokeswoman countered: "Dumping tea in Boston wasn't going to bring down the British Empire—but it created a spark that started the Revolution." (More energy stories.)
