WASHINGTON — Former Vice President Al Gore called Thursday for a "man on the moon" effort to switch all the nation's electricity production to wind, solar and other carbon-free sources within 10 years.
It is a goal that would solve global warming as well as economic- and national-security crises caused by dependence on fossil fuels, Gore said.
"The answer is to end our reliance on carbon-based fuels," Gore told a packed auditorium in Washington's historic Constitution Hall.
"When you connect the dots, it turns out that the real solutions to the climate crisis are the very same measures needed to renew our economy and escape the trap of ever-rising energy prices."
Gore compared the challenge to establishing Social Security and the interstate highway system, as well as landing a man on the moon — all successes that took more than a single presidency to accomplish and required members of both political parties to overcome their partisanship.

The Alliance for Climate Protection, a bipartisan group Gore leads, put the 30-year cost of his plan — both government and private — at $1.5 trillion to $3 trillion.
To speed up the transition to new energy sources, Gore said the single most important policy change would be to "tax what we burn, not what we earn," advocating a tax on carbon dioxide pollution.
Gore's proposal would represent a significant shift in where the U.S. gets its power. In 2005, coal supplied slightly more than half the nation's 3.7 billion kilowatt-hours of electricity.
Nuclear power accounted for 21 percent, natural gas 15 percent and renewable sources, including wind and solar, about 8.6 percent.
Gore shared the Nobel Peace Prize for sounding the alarm about climate change and his documentary on the issue, "An Inconvenient Truth," won an Oscar.
In his speech, he did not address what to do about coal, which is responsible for more than a third of U.S. carbon dioxide pollution, the most prevalent of the greenhouse gases blamed for global warming.
Coal's share of electricity generation is only expected to grow between now and 2030, according to Energy Department forecasts that assume no new government controls will be put on pollution.
Renewable energy resources' share of the power production would grow to 11 percent under that scenario.
In an interview with The Associated Press after his speech, Gore said coal's place in the nation's energy future will depend on whether the industry cuts back on carbon.
"Even coal has a role to play if the carbon dioxide is captured and safely buried … but clean coal does not exist right now," Gore said.
Gore told the AP his plan counts on nuclear power plants still providing about a fifth of the nation's electricity as the U.S. dramatically increases it's use of solar, wind, geothermal energy and clean coal technology.
He said one of the largest obstacles will be updating the nation's electricity grid to harness power from solar panels, windmills and dams and transport it to cities.
The Edison Electric Institute, the private utility industry's trade association, said it shares Gore's support for more renewable generation, a "smarter" power grid and the eventual use of plug-in electric vehicles.
"But we cannot do the job with renewable and efficiency alone," it said.
A portfolio for the future must also include "an expanded role for nuclear energy, as well as natural gas and clean coal with carbon capture and storage."
