When it comes to energy policy, there is no perfect fuel. But in these debates, as elsewhere, the imaginary perfect fuel cannot become the enemy of the good.

And for the first time in recent memory, this means that nuclear energy, by all accounts a good alternative for the scale of demand we face, might be getting a seat at the table. Coal, which still provides more than half of the energy for the American grid, is cheap and plentiful, but environmentally and politically costly. And according to Popular Mechanics, it can only be “cleaned” up so much. That leaves a huge gap for other sources to fill.

As James B. Meigs writes,

Coal will never be clean. It is possible to make coal emissions cleaner. In fact, we’ve come a long way since the ’70s in finding ways to reduce sulfur–dioxide and nitrogen-oxide emissions, and more progress can be made. But the nut of the clean-coal sales pitch is that we can also bottle up the CO2 produced when coal is burned, most likely by burying it deep in the earth. That may be possible in theory, but it’s devilishly difficult in practice.

The rest of the piece goes on to argue how we’re really talking about “cleaner” coal, rather than “clean” coal. Remember that debate over whether it was appropriate to call sex with various forms of birth control “safe” or “safer”? We might well see a similar shift in language about coal from “clean” to “cleaner.”

But what about so-called “alternative” energy sources, like geothermal, wind, and solar? Well, as John Whitehead over at the Environmental Economics blog concludes, “…potential supplies of wind and solar don’t appear to be large enough to completely replace oil and coal in the foreseeable future. If that is the purpose, then no, alternative energy can not effectively replace fossil fuels.”

So for the foreseeable future what we’re looking at in terms of the sources of our energy, in the face of growing global demand, is a mélange; coal, oil, natural gas, and yes, wind and solar, all have their place. But so does nuclear, and that’s one of the positive takeaways from President Obama’s State of the Union address, in which he commended “building a new generation of safe, clean nuclear power plants in this country.”

The challenging for existing energy firms will be to adjust to providing the right sources in this mixture. One way to do this is to be cognizant of the alternatives and their relative costs and benefits. ExxonMobil’s “Energy Outlook” released at the end of last year predicted that the growth of some of the newer sources, like wind and solar, would grow faster than some of the conventional sources, like oil and coal.

This means that a focus on innovation and efficiency will move some surprising players to fill the demand for cleaner energy, and the vision of increasingly transient reliance on fossil fuels might indeed come to pass.

As I wrote in 2006, “The human stewardship of oil and other petroleum-based fuels entails a responsibility to use the economic opportunities they afford to find and integrate other renewable, sustainable, and cleaner sources of energy, especially represented by the promise of nuclear power, into our long-term supply.”

Juliet Eilperin, “Bush Pollution Curbs Are Rated Equal to Clinton’s: Science Panel Says Proposed Cap-and-Trade System Will Help Clean Air,” Washington Post, July 24, 2006:

The report from the National Academy of Sciences, released yesterday, represents the latest effort to assess how best to reduce air pollution estimated to cause as many as 24,000 premature deaths each year. The panel concluded that an earlier Bush plan would have allowed pollution to increase over a dozen years, but it found that the administration’s more recent Clean Air Interstate Rule (CAIR) — which targets emissions from power plants in 22 states and the District of Columbia — would help clean the air over the next two decades.

The CAIR approach aims to reduce nitrogen oxide and sulfur dioxide emissions by 70 percent by 2025 at the latest, according to the Environmental Protection Agency, through a system that would allow utilities to sell and buy pollution credits as long as industry emissions as a whole stayed below a pre-set cap.

Cap-and-trade schemes may be better than command-and-control techniques, but maybe they’re not all they’re cracked up to be.

Hugh Ross, “The Faint Sun,” Facts for Faith, Reasons to Believe, 2002:

The timing of humanity’s arrival—near the end of life’s long tenure on Earth—may appear tragic at first glance. But a longer look suggests it may be viewed as a gift. Scanning the horizon of civilization—farms, ranches, towns, cities, and all the transportation and communication arteries linking them—one sees a plethora of building materials derived from nearly 4 billion years of life and death: gems, sand, steel, asphalt, concrete, copper, limestone, marble, plastics, etc. Most of the energy that drives civilization comes from biodeposits—oil, coal, wood, kerogen, natural gas, and so forth. Many of the fertilizers that support agricultural production also come from biodeposits—phosphates, nitrates, and such.

Such bountiful provisions powerfully indicate a Provider who carefully planned and prepared the planet through the ages for human life. They speak of a purpose for the human race. The Bible reveals a purpose that involves, yet goes beyond, the current “heavens and Earth.”

Associated Press, “Christian Ministry Wants to Build Turbines to Spread the Gospel,” The Church Report, July 23, 2006:

A Christian ministry group wants to build 36 wind turbines on the roof of a former steel company to generate money to help spread its message….

Energy produced by the turbines will be sold back to Wisconsin Energy Corp. through a buyback program.

Arnold Kling at the excellent EconLog says that “the government should empty its strategic petroleum reserve and buy energy futures contracts instead. At some point, the futures market has to be taken seriously.”

He concludes, “The government has all sorts of subsidies for alternative energy. However, the most efficient subsidy would be to buy oil futures contracts. If we must have an energy policy, it should consist solely of strategic futures market purchases.”

This on the heels of the announcement by Whole Foods Market Inc. that “the company is buying enough wind power credits to cover energy use at all of its U.S. stores, bakeries, distribution centers, regional offices and its Austin headquarters.” For Acton research fellow Anthony Bradley’s take on wind power, click here (and listen here for a radio interview [mp3] with Bradley on the subject). Read here about offshore wind farms.

I’m all in favor of the market determining what alternative energy sources there are and who decides to use them. Good for Whole Foods, I wish them luck. I’m not convinced, however, that I need to help pay for their switch to wind power, which government subsidies for such ensure that I do. Nuclear energy deserves a second look, and the harsh realities of energy markets is forcing even Europe to recognize this, as various European nations slate the construction of new nuclear reactors.
