Statement at COP21, December 4, 2015

Many years ago, I was protesting against nuclear power at the Shoreham Nuclear Plant on Long Island and I was arrested for protesting nuclear power. At that time, I thought, we had bioenergy and some wind and solar and that would be enough to solve the problem.

I’ve come to see now that the magnitude of the problem is so great that we can’t afford to leave technologies unused that can potentially help.

There’s really only one technology that I know of that can provide carbon free power [at the scale required by modern civilization] when the sun is not shining and the wind is not blowing at the scale modern civilization requires and that is nuclear power.* And whatever you think of nuclear power, we need to let it compete on its own merits given an appropriate regulatory environment and a sensible, cost-competitive market situation.

And we shouldn’t discriminate against individual technologies. It’s not about either/or, we’re not talking about whether we favor solar power, wind or nuclear power; I’m in favor of anything that can prevent climate change, protect the environment and allow poor people to get food and health care and education.**

The basic plea here is let’s focus on the climate agenda, and the climate agenda is about supplying energy [services] in a way that does not damage our environment.*** We need to allow technologies to compete on their own merits.

These were extemporaneous verbal comments made at a press conference at COP21 in Paris. Thus not every sentence contained every qualifier it needed, and not every important point was made.

*Qualifier about scale added here.

**This is not a complete list of filters. Key is that the technologies should be able to “compete on its own merits given an appropriate regulatory environment and a sensible, cost-competitive market”. This would include considerations of safety, etc.

***This should have read ‘energy services’ instead of ‘energy’. We need to work to provide more energy services with less energy consumption.

Am I capable of not rejecting nuclear power?

It is time for people to rethink their positions on nuclear power, and make arguments based on facts rather than prejudices.

Any good scientist and any good citizen should be constantly re-examining their positions, so the basic call for us to rethink our position on nuclear power is most welcome. I hope that the signers of this Civil Society Institute letter can bring themselves to re-examine the nuclear power issue with the same objectivity and lack-of-bias that they seek from us.

The letter confusedly suggests that I “embrace nuclear power”, and implies that I somehow discount the importance and potential of solar, wind, and efficiency. I cannot speak on behalf of my colleagues, but at least in my case, these claims are far from the truth.

We embrace things that we love. I don’t love nuclear power. Nuclear power has brought us Chernobyl and Fukushima. If the current industry were scaled up enough to solve the climate problem, there would be one such accident each year — and that is clearly unacceptable. Were I king of the world, I would decree that solar, wind, and efficiency would be the primary means we deploy to solve the climate problem.

But there is no energy storage system that works at the scale of the modern megalopolis. We need a way to power civilization when the sun is not shining and when the wind is not blowing. In a modern real economy, not ruled by benevolent kings, reliable power is required at competitive prices. There are very few technologies that can provide this reliable baseload power. Fossil fuels and nuclear power are the two leading candidates. I think an objective assessment of the facts shows that fossil fuels are far more dangerous than even today’s nuclear power.

But I do not defend today’s nuclear power industry. Even though most nuclear power plants have an excellent safety record, there are an important few that do not. There is no justification for the claim that this important type of electricity generation can never be made sufficiently safe and inexpensive.

To say that an entire category of technology can never be sufficiently improved is, I think, to adopt a position of technological myopia, where one lacks to the capacity to imagine that future technologies can differ substantially from today’s technologies.

I do not embrace nuclear power. There is no power source that one wants to embrace. They all have negative consequences. I do not want a solar PV factory, a massive wind turbine, or a nuclear power plant in my back yard. But I want the juice. The question is not about what power source I embrace, but about what power source I might think myself capable of not rejecting. Many people want to reject power sources, but want the juice that comes from those power sources.

In summary, I applaud the signers of the Civil Society Institute letter for their concern regarding climate change and for their support of solar, wind, and efficiency. Their call for us to rethink our positions on nuclear power is most welcome, and I ask only that they rethink their position with respect to nuclear power with the same degree of receptivity and objectivity that they ask of us.

This is from an email to John Upton on 10 Jan 2014. It, along with the ‘Civil Society Institute letter’ is included in his Grist piece: Enviros and climate scientists continue their fight over nuclear power
