In India, 620-million people are without power after three regional power grids collapsed, creating one of the world's biggest-ever blackouts.
The blackout has raised concerns about the country's outdated electric system and its inability to meet the huge energy demand. And many wonder if this could ever happen in the US.
Effects have been far reaching in the country. Transportation grinded to a halt in India, as hundreds of trains stalled and traffic lights went out, causing widespread traffic jams in cities like New Delhi. Electric crematoria stopped operating, leaving some bodies half-cremated. Coal miners were trapped underground while awaiting generators to be brought to the scene.
According to Maggie Koerth-Baker, author of "Before the Lights Go Out," a similar power outage would be unlikely in the U.S. A massive power outage occured in August 2003, when 15 percent of the population was out of power for roughly 16 hours.
