Like medieval priests, today’s carbon brokers will sell you an indulgence that forgives your carbon sins. It will run you about $500 for 5 tons of forgiveness—about how much the typical American needs every year. Or about $2,000 a year for a typical four-person household. Your broker will spend the money on such things as reducing methane emissions from hog farms in Brazil.I'm not convinced carbon sequestration can be done cost effectively. But I'm a technology optimist. If Obama would invest in coal-based "green" technology, I suspect an effective, scalable solution can be found.

Windmills are now 50-story skyscrapers. Yet one windmill generates a piddling 2 to 3 megawatts. A jumbo jet needs 100 megawatts to get off the ground; Google is building 100-megawatt server farms. Meeting New York City’s total energy demand would require 13,000 of those skyscrapers spinning at top speed, which would require scattering about 50,000 of them across the state, to make sure that you always hit enough windy spots. To answer the howls of green protest that inevitably greet realistic engineering estimates like these, note that real-world systems must be able to meet peak, not average, demand; that reserve margins are essential; and that converting electric power into liquid or gaseous fuels to power the existing transportation and heating systems would entail substantial losses. What was Mayor Bloomberg thinking when he suggested that he might just tuck windmills into Manhattan? Such thoughts betray a deep ignorance about how difficult it is to get a lot of energy out of sources as thin and dilute as wind and sun.

But uranium aside, the most economical substitute for oil is, in fact, electricity generated with coal. Cheap coal-fired electricity has been, is, and will continue to be a substitute for oil, or a substitute for natural gas, which can in turn substitute for oil. By sharply boosting the cost of coal electricity, the war on carbon will make us more dependent on oil, not less.
The first place where coal displaces oil is in the electric power plant itself. When oil prices spiked in the early 1980s, U.S. utilities quickly switched to other fuels, with coal leading the pack; the coal-fired plants now being built in China, India, and other developing countries are displacing diesel generators. More power plants burning coal to produce cheap electricity can also mean less natural gas used to generate electricity. And less used for industrial, commercial, and residential heating, welding, and chemical processing, as these users switch to electrically powered alternatives. The gas that’s freed up this way can then substitute for diesel fuel in heavy trucks, delivery vehicles, and buses. And coal-fired electricity will eventually begin displacing gasoline, too, as soon as plug-in hybrid cars start recharging their batteries directly from the grid.
To top it all, using electricity generated in large part by coal to power our passenger cars would lower carbon emissions—even in Indiana, which generates 75 percent of its electricity with coal. Big power plants are so much more efficient than the gasoline engines in our cars that a plug-in hybrid car running on electricity supplied by Indiana’s current grid still ends up more carbon-frugal than comparable cars burning gasoline in a conventional engine under the hood. Old-guard energy types have been saying this for decades. In a major report released last March, the World Wildlife Fund finally concluded that they were right all along.
But true carbon zealots won’t settle for modest reductions in carbon emissions when fat targets beckon. They see coal-fired electricity as the dragon to slay first. Huge, stationary sources can’t run or hide, and the cost of doing without them doesn’t get rung up in plain view at the gas pump. California, Pennsylvania, and other greener-than-thou states have made flatlining electricity consumption the linchpin of their war on carbon. That is the one certain way to halt the displacement of foreign oil by cheap, domestic electricity.
The oil-coal economics come down to this. Per unit of energy delivered, coal costs about one-fifth as much as oil—but contains one-third more carbon. High carbon taxes (or tradable permits, or any other economic equivalent) sharply narrow the price gap between oil and the one fuel that can displace it worldwide, here and now. The oil nasties will celebrate the green war on carbon as enthusiastically as the coal industry celebrated the green war on uranium 30 years ago.
The other 5 billion are too poor to deny these economic realities. For them, the price to beat is 3-cent coal-fired electricity. China and India won’t trade 3-cent coal for 15-cent wind or 30-cent solar. As for us, if we embrace those economically frivolous alternatives on our own, we will certainly end up doing more harm than good.

Perhaps it’s the recognition of that inconvenient truth that has made the anti-carbon rhetoric increasingly apocalyptic. Coal trains have been analogized to boxcars headed for Auschwitz. There is talk of the extinction of all humanity. But then, we have heard such things before. It is indeed quite routine, in environmental discourse, to frame choices as involving potentially infinite costs on the green side of the ledger. If they really are infinite, no reasonable person can quibble about spending mere billions, or even trillions, on the dollar side, to dodge the apocalyptic bullet.
Thirty years ago, the case against nuclear power was framed as the “Zero-Infinity Dilemma.” The risks of a meltdown might be vanishingly small, but if it happened, the costs would be infinitely large, so we should forget about uranium. Computer models demonstrated that meltdowns were highly unlikely and that the costs of a meltdown, should one occur, would be manageable—but greens scoffed: huge computer models couldn’t be trusted. So we ended up burning much more coal. The software shoe is on the other foot now; the machines that said nukes wouldn’t melt now say that the ice caps will. Warming skeptics scoff in turn, and can quite plausibly argue that a planet is harder to model than a nuclear reactor. But that’s a detail. From a rhetorical perspective, any claim that the infinite, the apocalypse, or the Almighty supports your side of the argument shuts down all further discussion.

If we do need to do something serious about carbon, the sequestration of carbon after it’s burned is the one approach that accepts the growth of carbon emissions as an inescapable fact of the twenty-first century. And it’s the one approach that the rest of the world can embrace, too, here and now, because it begins with improving land use, which can lead directly and quickly to greater prosperity. If, on the other hand, we persist in building green bridges to nowhere, we will make things worse, not better. Good intentions aren’t enough. Turned into ineffectual action, they can cost the earth and accelerate its ruin at the same time.
I think Huber's dose of "pessimism" is essential to break the spell of eco-activist who have a quasi-religious faith that their green philosophy is non-negotiable. I'm encouraged that Obama is acting as a pragmatist and hasn't be captured by the crazies. I do believe he will diversify his bets and use technology as the technique to deal with the energy crisis.
