Gore wants carbon-free power by 2018

Former Vice President Al Gore said 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.”

Mr. Gore called for the kind of concerted national effort that enabled Americans to walk on the moon 39 years ago this month, just eight years after President John F. Kennedy famously embraced that goal. He said the goal of producing all of the nation’s electricity from “renewable energy and truly clean, carbon-free sources” within 10 years is not some farfetched vision, although he said it would require fundamental changes in political thinking and personal expectations.

“This goal is achievable, affordable and transformative,” Mr. Gore said in his remarks at the conference. “It represents a challenge to all Americans, in every walk of life — to our political leaders, entrepreneurs, innovators, engineers, and to every citizen.”

Although Mr. Gore has made global warming and energy conservation his signature issues, winning a Nobel Prize for his efforts, his speech argued that the reasons for renouncing fossil fuels go far beyond concern for the climate.

In it, he cited military-intelligence studies warning of “dangerous national security implications” tied to climate change, including the possibility of “hundreds of millions of climate refugees” causing instability around the world, and said the United States is dangerously vulnerable because of its reliance on foreign oil.

Doubtless aware that his remarks would be met with skepticism, or even ridicule, in some quarters, Mr. Gore insisted in his speech that the goal of carbon-free power is not only achievable but practical, and that businesses would embrace it once they saw that it made fundamental economic sense.

Mr. Gore said the most important policy change in the transformation would be taxes on carbon dioxide production, with an accompanying reduction in payroll taxes. “We should tax what we burn, not what we earn,” he said.

The former vice president said in his speech that he could not recall a worse confluence of problems facing the country: higher gasoline prices, jobs being “outsourced,” the home mortgage industry in turmoil. “Meanwhile, the war in Iraq continues, and now the war in Afghanistan appears to be getting worse,” he said.

By calling for new political leadership and speaking disdainfully of “defenders of the status quo,” Mr. Gore was hurling a dart at the man who defeated him for the presidency in 2000, George W. Bush. Critics of Mr. Bush say that his policies are too often colored by his background in the oil business.

A crucial shortcoming in the country’s political leadership is a failure to view interlocking problems as basically one problem that is “deeply ironic in its simplicity,” Mr. Gore said, namely “our dangerous over-reliance on carbon-based fuels.”

“We’re borrowing money from China to buy oil from the Persian Gulf to burn it in ways that destroy the planet,” Mr. Gore said. “Every bit of that’s got to change.”

And it can change, he said, citing some scientistsÂ’ estimates that enough solar energy falls on the surface of the earth in 40 minutes to meet the worldÂ’s energy needs for a year, and that the winds that blow across the Midwest every day could meet the countryÂ’s daily electricity needs.

Senator Barack Obama of Illinois, the presumptive Democratic candidate for president, immediately praised Mr. Gore’s speech. “For decades, Al Gore has challenged the skeptics in Washington on climate change and awakened the conscience of a nation to the urgency of this threat,” Mr. Obama said.

A shift away from fossil fuels would make the United States a leader instead of a sometime rebel on energy and conservation issues worldwide, Mr. Gore said. Nor, he said, would the hard work of people who toil on oil rigs and deep in the earth be for naught. “We should guarantee good jobs in the fresh air and sunshine for any coal miner displaced by impacts on the coal industry,” he said by way of example. “Every single one of them.”

“Of course, there are those who will tell us that this can’t be done,” he conceded. “But even those who reap the profits of the carbon age have to recognize the inevitability of its demise. As one OPEC oil minister observed, ‘The Stone Age didn’t end because of a shortage of stones.’ ”
