Strategic Importance
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
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
