The answer is to end our reliance on carbon-based fuels.
and
Today I challenge our nation to commit to producing 100 percent of our electricity from renewable energy and truly clean carbon-free sources within 10 years.
Sounds good, maybe. But in the early 1990s, Al Gore denied us truly clean carbon-free nuclear power.
When hit by neutrons, uranium atoms either split (giving off energy, neutrons and fission products) or transmute into heavier elements (the transuranics). So reactors produce two kinds of nuclear waste: fission products and transuranic elements.
Fission products are only dangerous for a couple of hundred years. I've seen plenty of buildings in Europe and elsewhere that old, so I'm confident we can safely store fission product waste until it decays to harmless dirt.
Transuranic elements can be dangerous for tens or hundreds of thousands of years. Safely disposing that waste is a lot harder, particularly if you care about your great-great-great-great-grand kids.
But transuranic elements can be recycled. You chemically separate them from the fission products and put them back into reactors. Over time the transuranics "burn up", producing power while being converted into easily handled fission products.
One of the transuranic elements is plutonium. The Fat Man bomb that dropped on Nagasaki used a plutonium core.
Jimmy Carter decided that the risks of terrorist diversion of plutonium outweighed the benefits of recycling nuclear waste into new fuel. He feared shipments of reactor fuel could be hijacked by terrorists. Other presidents have upheld that policy. So the United States government refuses to allow industry to recycle nuclear reactor fuel. (France, Russia and Japan all recycle their nuclear reactor fuel, which is why they don't have a nuclear waste problem.)
15 years ago I was a new employee of Argonne National Laboratory. As a student I had worked with Argonne staff on the Integral Fast Reactor (IFR) project. It aimed to demonstrate on-site fuel recycling, eliminating the possibility of hijacking shipments of spent fuel. It also demonstrated the inherent safety of a sodium coolant reactor.
The IFR project ended on September 30, 1994. Al Gore killed it.
When the Clinton administration took office in early 1993, they immediately decided to kill the IFR project. I think their constituents in the anti-nuke community saw that the IFR project answered most of their arguments against nuclear power. So Al Gore and Hazel O'Leary stripped all IFR funding out of the administration's Fiscal Year 1994 Federal budget request.
The nuclear industry and scientists lobbied Congress to preserve the IFR project. Congress added the funding back in to the FY1994 budget.
Word then came down from DOE headquarters to us at Argonne that if anyone so much as used a sheet of copier paper to write a letter to Congress or the media supporting IFR, that person would be criminally prosecuted for misappropriation of government property and other charges related to illegal lobbying activity. The administration (Al Gore and Hazel O'Leary) wanted IFR dead.
Through a combination of bullying the scientists and doing their own lobbying, the Clinton administration managed to keep IFR funding out of the FY1995 budget as passed by Congress. So the IFR project ended on September 30, 1994, the last day of the 1994 Fiscal Year.
Skip forward 13 years. Al Gore presents a speech on the "climate crisis", calling for the end of carbon-based electricity generation. But his jeremiad omits the very mention of the word nuclear. He still thinks it's more important to keep the irrationally anti-nuke crowd happy than save the planet from carbon dioxide pollution.
I will believe Al Gore really cares about greenhouse gasses when he admits his mistakes in 1993 and 1994, or at least reverses himself on nuclear power.
