While the context of George Monbiot’s article on nuclear energy is British politics, it’s directly relevant to the US as well.
Ten cents of investment, he shows, will buy either 1 kilowatt-hour of nuclear electricity; 1.2-1.7 of windpower; 2.2-6.5 of small-scale cogeneration; or up to 10 of energy efficiency. “Its higher cost than competitors, per unit of net CO2 displaced, means that every dollar invested in nuclear expansion will worsen climate change by buying less solution per dollar.†And, because nuclear power stations take so long to build, it would be spent later. “Expanding nuclear power would both reduce and retard the desired decrease in CO2 emissions.â€
…
It’s certainly a good idea, as people like Sir David recommend, to have a “diversified energy portfolioâ€. But, as Lovins points out, “this does not mean … that every option merits a place in the portfolio purely for the sake of diversity, any more than a financial portfolio should include bad investments just because they’re on the market.†Building new nuclear power stations in the United Kingdom would be a political decision, not a scientific one.
I like the fact he pointed out that energy efficiency has way more bang for the buck than the other choices on the list. That is true for mobile as well as stationary consumption. If we could just get all those consumers out there on their bicycles the price of gasoline would plumet!
Tim Worstall pointed out a major flaw in Monbiot’s analysis yesterday.
There’s an ongoing dispute about what constitutes an apples-to-apples comparison of costs. The Guardian article that Worstall cites, for example, also says,
The picture in the US is even murkier, with the newly renewed Price-Anderson Act subsidizing and capping the nuclear industry’s liability.
I’m reminded of the ongoing and unresolved dispute over the net energy gain in using alcohol as a gasoline substitute. None of the studies I’ve read are entirely convincing.
These issues bring together some very disparate groups. For example both the Sierra Club (Carl Pope) and the Cato Institute (Jerry Tailor) are talking about a zero-subsidy energy policy from the Federal Government.
With that kind of advantage, Green sources just might win.
Wind power is cheap, but fuel recycling with fast neutron reactors will reduce nuclear waste to 1 percent of the original material, with none of it capable of being useful for making weapons. In the long run, both could be equally cost-effective sources of power. See the article in the December 2005 issue of “Scientific American” on the future of nuclear power plants.
