Earth Hour 2011

Some critics point out that the reduction in power consumption in most cases is indistinguishable from zero. Sydney's The Herald Sun equated the power savings in the Sydney central business district to "taking 48,613 cars off the road for 1 hour." Critics, most notably Australian Columnist Andrew Bolt pointed out that "A cut so tiny (48,613 cars off the road for 1 hour) is trivial - equal to taking six cars off the road for a year".
