Blackoutsabbath is a concept created by Canadian-American singer-songwriter Rufus Wainwright, as promoted by the organization Blackout Sabbath. In an attempt to become more environmentally conscious, participants are asked to live "off the grid" as much as possible on a designated date by unplugging appliances, walking or cycling for transportation, turning out lights and decreasing energy usage in any other ways possible.
As the sun sets on the evening of Blackoutsabbath, participants write down a list of ways they can contribute to the earth's well-being throughout the rest of the year. Annual benefit concerts take place to raise awareness of the cause. The organization's official site contains updates about the program and contains links to various tools, green products and services, studies, and groups that promote energy conservation and environmental protection.[1]
