August 14th Blackout By-The-Numbers 1 Canadian Province 3 deaths 8 U.S. states 12 airports closed 23 cases of looting in Ottawa 250+ power plants 9,266 square miles 61,800 MW of power lost 1.5 mill Cleveland residents without water 50 million people $4.5-10 billion in economic activity lost Strategic Importance “…it's clear that the power grid needs an overhaul. It needs to be modernized. As we go into an exciting new period of American history, we want the most modern electricity grid for our people… we need more investment; we need research and development…” President Bush September 2003 “When the lights go out, modern life as we know it grinds to a sudden halt. Transportation is interrupted, communications fail, water systems shut down, factory work is disrupted, food spoils, businesses lose money, and people are inconvenienced and even endangered. ” Secretary Abraham April 2004
