Earth Hour is an event that inspires individuals, communities, households and businesses to participate through the simple symbolic act of turning lights off for one hour.
The eighth annual event will be held this Saturday, March 29 from 8:30 p.m. to 9:30 p.m. More than 7,000 cities across the globe will turn their non-essential lights off to demonstrate their collective commitment to the planet.
Energy conservation is critical for reducing energy demands and curbing development that threatens our wild lands. For example, avoiding the construction of a 1,000-megawatt coal-fired power plant saves about 23,500 acres from losing its wild character.
This year's Earth Hour event includes the launch of a crowdfunding and crowdsourcing platform called Earth Hour Blue, which aims to raise money for environmental efforts around the world, like reforestation and renewable energy projects.
Earth Hour 2014 also has partnered with the cast and crew of "The Amazing Spider-Man 2", a film that was produced carbon-neutrally through offsets.
