SAN FRANCISCO--Former US vice president Al Gore said Friday that an Internet revolution carrying Barack Obama to the White House should now focus its power on stopping Earth's climate crisis.

The one-time presidential contender turned environmental champion told Web 2.0 Summit goers in San Francisco that technology has provided tools to save the planet while creating jobs and stimulating the crippled economy.

"The young people who have been inspired by Barack Obama's campaign and the movement that powered Barack Obama's campaign want a purpose," Gore said.

"One of the reasons we were all thrilled Tuesday night is it was pretty obvious this was a collectively intelligent decision."

The Internet's critical role in Democrat Obama's victory in the presidential race against Republican John McCain was a "great blow for victory" in addressing a "democracy crisis" stifling action against climate change, Gore said.

The Web has "revolutionized" nearly every aspect of running for US president and delivered an "electrifying redemption" of the founding national principle that all people are created equal, according to Gore.

"Some week," Gore said in greeting to an audience that leapt to its feet cheering. "It really was overwhelming. It couldn't have happened without the Internet."

Obama's victory, seen by many as a repudiation of policies of president George W. Bush, was validation of sorts for Gore, who lost to Bush in a controversial election outcome in 2000.

"Belated redemption is part of what we are celebrating this week," Gore said.

Since leaving politics Gore has been awarded a Nobel Peace Prize for his relentless efforts to combat climate change and starred in an Academy Award-winning global warming documentary "An Inconvenient Truth."

He also founded Current TV, a cable television operation that taps into user-generated videos and news coverage fed to its website.

"What happened in the election opens a full new range of possibilities and now is the time to really move swiftly to exploit these new possibilities," Gore said of turning the power of the Internet to cooling global warming.

Gore said Obama should announce a national goal of getting all US electric power from renewable energy within the next decade and spend the billions necessary to build an "electrinet" smart power grid.

"Web 2.0 has to have a purpose," Gore said.

"The purpose I would urge is to bring about a higher level of consciousness about our relationship to this planet and the imminent danger we face. We have everything we need to save it."
