A general view from Exchange Place shows the skyline of lower Manhattan in darkness after a preventive power outage caused by giant storm Sandy in New York October 30, 2012. Millions of people in the eastern United States awoke on Tuesday to flooded homes, fallen trees and widespread power outages caused by Sandy, which swamped New York City's subway system and submerged streets in Manhattan's financial district. More than two-thirds of the U.S. East Coast's refining capacity was shut down and fuel pipelines idled due to Hurricane Sandy. Early assessments show the region's biggest plants may have escaped without major damage. REUTERS/Eduardo Munoz
