WASHINGTON – From North Carolina to New Jersey, 2 million people without electricity are asking the same question: Why will it take so long to get the lights back on?

Nearly three full days after a severe summer storm lashed the East Coast, utilities warned that many neighborhoods could remain in the dark for much of the week, if not beyond.

Friday's storm arrived with little warning, so utility companies have had to wait days for extra crews traveling from as far away as Quebec and Oklahoma. And the toppled trees and power lines often entangled broken equipment in debris that must be removed before workers can even get started.
