Gore Calls for Carbon-Free Electric Power

By DAVID STOUT

WASHINGTON — Former Vice President Al Gore said on Thursday that Americans must abandon electricity generated by fossil fuels within a decade and rely on the sun, the winds and other environmentally friendly sources of power, or risk losing their national security as well as their creature comforts.

“The survival of the United States of America as we know it is at risk,” Mr. Gore said in a speech to an energy conference here. “The future of human civilization is at stake.”
