From weather events to human error, a range of snafus can wreak havoc for millions when they create the massive blackouts that have periodically struck regions around the world. A full moon created an eerie skyline silhouette after New York City went dark during the blackout of November 1965. Onlookers wait for the newly built cruise ship Norwegian Pearl to leave the Papenburg, Germany, shipyard in November 2006. A lack of power poses plenty of inherent problems, but massive blackouts can also lead to bad behavior. On August 15, 2003, a mass of New York commuters crossed the Brooklyn Bridge on foot during a blackout that robbed 50 million people of power for as long as two days in southeastern Canada and the Northeastern United States. Historic winter storms decimated this electrical tower and other parts of the grid in China's southern Hunan province during February 2008.
On November 10, 2009, the power supply dried up at the massive hydroelectric works at the Itaipu Dam and plunged 67 million people into darkness, including these SA?o Paulo pedestrians waiting to cross the street.
Fewer than 250 adult Bawean warty pigs are alive todaya€”meaning they're likely an endangered species, a new study says.

Southeast of New England, buoy 44008 is recording seas as high as 29.2 feet already this morning. Despite pressure rising rapidly storm surge values of 3+ ft currently being observed at Chatham & Nantucket. In a world that's increasingly dependent on constant power, massive electrical outages are a common concern and may strike systems across the globe.Major power disturbances can be triggered by storms, heat waves, solar flares, and many other sources, but all have roots in the mechanical and human vulnerabilities of the power grids themselves.
Soon after, on its trip down the River Ems, the ship indirectly caused a two-hour power outage for some 10 million people on the evening of November 4.The German power company E. A lightning-sparked outage in 1977, which left 9 million New Yorkers without power, lasted only about 24 hours on July 13 and July 14.


In Chenzhou, some 4.5 million people were without power for nearly two weeks, thanks to the effects of the worst storms in 50 years. Brazilian energy officials said storms short-circuited several vital transformers, completely cutting off power from the second largest hydroelectric source in the world.About one third of all Brazilians lost power for four hours, including those living in the nation's two largest cities. The outage's exact cause may be debatable, but the ultimate source of trouble was predictable: India's power structure is often unable to meet peak power demands. But during that time, arsonists torched buildings like these on Marmion Avenue in the Bronx, setting a reported 1,000 fires. All of Paraguay, which shares power from the border dam, also saw suspended service for a short time. But the dead line quickly increased pressures elsewhere in the German power grid and then sparked a chain reaction across parts of Germany, France, Belgium, Italy, Spain, Austria, the Netherlands, and Croatia. Looters and rioters also ran rampant and trashed some 1,600 stores during what Mayor Abraham Beame called "a night of terror." When similar outages struck the city in 2003, however, such problems were few and far between.
When this photo was taken on February 5, Chinese officials said 11 electricians had already lost their lives while attempting to repair infrastructure.Since that fateful winter, China has improved its abilities to monitor power system status and gather information that operators can use to prevent an initial failure from spreading to a much larger region.
In dynamic developing economies like Brazil, China, and India, the surging demand for power poses a significant challenge for systems that often are simply not up to meeting demand. A system is designed to tolerate a certain amount of disruption but past a certain point, it's simply gone too far and it falls apart."The "great Northeast blackout," which began when a power surge near Ontario set off a chain of failures across New York State and beyond, covered 80,000 square miles. A faulty or improperly set safety relay at an Ontario power station was blamed for sparking a southbound power surge that overwhelmed systems from Vermont to New Jersey. Critics said the incident showcased the need for more universal electricity distribution policies across Europe.
