Arizona had 48 major power outages last year, according to the Eaton Corporation, which tracks this information. Most of Arizona's outages are storm-related, but the state also tied for ninth among the states for vehicle-related outages. The Obama administration has issued a report saying severe weather is the number one cause of power outages, and has announced plans to strengthen the power grid, asserting that climate change will increase the intensity of storms. Josh Saks of the National Wildlife Federation says it is a wise move.
The White House report says power outages cost the nation anywhere from 18 to 33 billion dollars each year.
