Reason on energy: nuclear power and light bulbs

March 16, 2011

Lynne Kiesling

Two good articles on misguided government intervention and energy policy at Reason recommend themselves. Ron Bailey’s written a really excellent, clear, analysis of improved, safer reactor technology, and argues that the best response to the Fukushima accident is not a ban, but rather is innovation:

One hopeful possibility is that the Japanese crisis will spark the development and deployment of new and even safer nuclear power plants. Already, the Westinghouse division of Toshiba has developed and sold its passively safe AP1000 pressurized water reactor. …

One innovative approach to using nuclear energy to produce electricity safely is to develop thorium reactors. Thorium is a naturally occurring radioactive element, which, unlike certain isotopes of uranium, cannot sustain a nuclear chain reaction. However, thorium can be doped with enough uranium or plutonium to sustain such a reaction. Liquid fluoride thorium reactors (LFTR) have a lot to recommend them with regard to safety. Fueled by a molten mixture of thorium and uranium dissolved in fluoride salts of lithium and beryllium at atmospheric pressure, LFTRs cannot melt down (strictly speaking the fuel is already melted).

Ron accurately, in my view, argues that interventionist government energy policy is part of the reason why such technologies have had such a difficult time coming to market:

The main problem with energy supply systems is that for the last 100 years, governments have insisted on meddling with them, using subsidies, setting rates, and picking technologies. Consequently, entrepreneurs, consumers, and especially policymakers have no idea which power supply technologies actually provide the best balance between cost-effectiveness and safety. In any case, let’s hope that the current nuclear disaster will not substantially add to the terrible woes the Japanese must bear as a result of nature’s fickle cruelty.

Similarly, Jacob Sullum criticizes interventionist government energy policy for imposing the paternalist belief that individuals are not capable of making an intelligent decision about the costs, benefits, and tradeoffs involved in using either incandescent or compact fluorescent light bulbs. CFLs turn on too slowly, don’t work in dimmers, and don’t last long enough to make up for their higher cost … and yet, our government tells us that we have to use them because we are too short-sighted to include the environmental impact of incandescents in our decision-making? We should trust a bureaucracy that has mandated such an immature, inferior technology to make a better decision than we each can individually? Yeah, right.

I agree with Jacob when he concludes

I will be happy to use CFLs if and when their manufacturers get the kinks out, or LED bulbs when they become affordable. But I am not the only one who thinks we’re not there yet, judging from the Energy Department’s estimate that more than 80 percent of residential lights sockets were still occupied by incandescent bulbs last year.

By forcing this transition, the government is ignoring the preferences that most Americans have clearly expressed in the marketplace. Which explains why I cheered when I heard Paul declare: “You busybodies always want to do something to tell us how to live our lives better. Keep it to yourselves.”

How to build a nuclear power plant without captive ratepayers

December 1, 2009

Michael Giberson

Jonathon Fahey, at Forbes.com, explains “How NRG Energy Wants to Revive Nuclear Industry.”

In the early part of the decade proponents talked breathlessly of a nuclear renaissance in the U.S. Natural gas prices were high, electricity demand was rising, and it seemed that carbon emissions would soon be either taxed or limited. In 2005 Congress passed an energy bill that provided loan guarantees for construction of new nukes on top of tax credits for power produced by the first few new reactors. Utilities fell over themselves planning new nuclear plants– nearly 40 proposals were drawn up.

Four years later the country is where it was a decade ago, at 104 operating nuclear plants (producing 20% of its electric energy). Natural gas prices crashed, making nukes look comparatively more expensive. Carbon remains untaxed and uncapped, and the recession ate into electricity demand, pushing the need for new plants further into the future. Credit markets also dried up, while the pool of government loan guarantees, $18.5 billion, was smaller than the industry hoped for, enough probably for only three plants.

Now, while 17 nuclear projects are still active, only a half-dozen plant proposals are moving at full speed, led by the four projects that are finalists for federal loan guarantees….

The story notes that NRG is an independent power producer, not a regulated utility, and so “doesn’t have a pool of captive ratepayers (as Southern and Scana do) who will pay for construction or cost overruns.”  But that isn’t to say that NRG isn’t looking for help whereever they hope to find it.  The NRG plant is among the finalists for federal load guarantees and, if built, may qualify for up to $125 million a year in tax credits during each of the first eight years of production.  NRG is partnering with the municipal utility in San Antonio for the nuclear plant expansion, and has lined up (or is looking for) additional financial partners.

The NRG strategy is either “how to build a nuclear plant in this day and age” (in the words of the director of NRG’s nuclear ventures) or just a matter of “finding a series of suckers to take the risk off his hands” (in the words of a nuclear power critic).

Also in the WSJ: “There is No Such Thing as Nuclear Waste”

March 13, 2009

Michael Giberson

William Tucker, author of “Terrestrial Energy: How Nuclear Power Will Lead the Green Revolution and End America’s Long Energy Odyssey,” has an essay in today’s WSJ pinning the U.S. nuclear waste problem on decisions by Presidents Ford and Carter to abandon reprocessing of spent nuclear fuel.

The reasons for abandoning reprocessing – mostly fear that plutonium would end up as bombs in terrorist hands – are no longer such a concern (because other sources would be more convenient, should someone want to develop a bomb, than a U.S. reprocessing facility). Reprocessing dramatically reduces the waste disposal problem.

Tucker says, “France, which completely reprocesses its recyclable material, stores all the unused remains — from 30 years of generating 75% of its electricity from nuclear energy — beneath the floor of a single room at La Hague.” (Maybe the Nuclear Energy Institute could offer to store the unused material from reprocessing in the basement of their Washington, D.C., offices?)

Any good analyses comparing renewable and nuclear costs?

January 22, 2009

Lynne Kiesling

Today several items have floated across my radar screen contending that renewables are cheaper than nuclear power. Here, for example, is a snippet of a talk from Eric Schmidt of Google on the topic.

I can see the possibility, given the innovations in renewables, incorporating the savings in foregone wires construction (although that depends …), and the costs of construcing nuclear plants. I’m not sure either way, though, and it’s hard to get a good read because both industries have such convoluted subsidies. Moreover, researchers are working on cheaper, more modular, smaller scale nuclear plants, so the fact that both industries are experiencing innovation makes answering this question even more difficult.

Have you seen any good analyses comparing these costs? I’m keen to learn more.
