World's top massive power outages
The energy crisis affecting half of India is the latest in a string of massive power outages that have cut electricity to millions of people around the world in recent years.
Three of India's regional power grids collapsed Tuesday, leaving 620 million people without government-supplied electricity in one of the world's biggest-ever blackouts.
Other massive power outages include:
- On Nov. 10, 2009, storms near the Itaipu hydroelectric dam on the Paraguay-Brazil border were blamed for outages that cut power to as many as 60 million people in Brazil for two to three hours. The entire nation of Paraguay, population seven million, was also briefly blacked out.
- A German power company switched off a high voltage line over a river to let a cruise ship pass in November 2006. It triggered outages for 10 million people in Germany, France, Italy and Spain.
