Commuters wait for buses outside a Metro station after Delhi Metro rail services were disrupted following power outage in New Delhi, India, Tuesday, July 31, 2012. Indian officials say the nation's northern and eastern power grids have failed, leaving about half the country without power. The collapse of the grids Tuesday afternoon came a day after the northern grid failed and left eight states without power for much of the day.(AP Photo/ Rajesh Kumar Singh) less
