More Inconvenient Truth About Ethanol

Holman Jenkins' Wednesday Wall Street Journal article about the far left castigating Toyota for its stand on CAFE standards. Standing with other auto manufacturers who rely on large, less fuel-efficient, profitable cars that people actually want, to fund the sale of the "profitless Prius," Toyota is catching flack from the same greenies who buy its hybrid car.

To provide us with a better understanding of the issue, Holman distills it thusly,

"As car companies do, it sold Prius customers a car that met their needs and/or flattered their vanity. For other customers whose hot buttons lie elsewhere, Toyota has the Tundra, its giant, fuel-consuming pickup. Auto companies only achieve efficient scale by appealing to different consumer appetites. The profitless Prius wouldn't exist if not for the non-hybrids that keep Toyota in business. Indeed, Toyota supports the House bill over the Senate bill only because it would let auto makers continue to make big vehicles that happen to be the ones Americans, with their dollars, show they actually want.

But the 32-year-old CAFE rules have become a fetish of environmental groups, a talisman of their clout, a ticket to a seat at a table in Washington. The policy itself has no value: It doesn't reduce oil imports. It doesn't meaningfully curb fossil-fuel use.

In the nature of things, auto buyers amortize their forced investment in fuel economy by driving more miles, burning more gas. The impressive reliability gains of the auto makers over the past 30 years are in part a reflection of this consumer demand for more miles. Ditto the conspicuous increase in vehicle size and comfort, partly a function of the increased time motorists spend in their cars."


To illustrate an as-yet unrealized hypocrisy, Jenkins notes, further down in the piece, this tasty little morsel concerning what converting to ethanol will do for total greenhouse gas emissions,

"A recently passed Senate bill would require motorists to buy 36 billion gallons a year by 2022, up from 7.5 billion gallons under current law.

At least this would benefit the atmosphere, right? Think again. A research team featuring Paul Crutzen, who won a Nobel Prize for his work on ozone depletion, recently showed that the intensive cultivation of biofuels in the U.S. and Europe produces up to 70% more greenhouse effect than the fossil fuels they displace (nitrous oxide, a byproduct of the fertilizers used, has nearly 300 times the heat-trapping properties of carbon dioxide).

Passenger cars can burn fuel consisting of 10% ethanol. If our goal were really to displace conventional gasoline, we'd open our coastal markets to sugar-cane ethanol from Brazil and other Southern Hemisphere countries, produced by less intensive methods that result -- irony alert -- in a genuine reduction in greenhouse emissions.

But Washington blocks imported ethanol with a 54-cents-a-gallon tariff to protect domestic ethanol profits. So let's sum up the ways you're paying to prop up an industry that's bad for energy security and bad for climate worries: higher taxes, higher gas prices and higher food prices. Did we mention the 3% mileage penalty that comes from burning gasoline with a 10% ethanol content, thanks to ethanol's inferior BTU value compared to gasoline?"

I have to admit, I love the naive hypocrisy of the populist environmentalists.

They want less oil usage. They want to buy expensive hybrid technology cars cheaply, even though the cars still don't make economic sense to operate. They want fewer greenhouse emissions while also advocating ethanol.

But, as Crutzen's work demonstrates, there's a contradiction. Moe ethanol means more greenhouse gases to cultivate the biofuels, not to mention soil erosion and forest depletion, as mentioned here. In fact, I've read an article, the exact location of which escapes me just now, that more widespread use of ethanol is likely to lead to the accelerated disappearance of South American rainforests, the better to be replanted with biofuels.

Call me crazy, but isn't it nonsensical to use a lot of a major food source to replace a more efficiently-burning fossil fuel? We can't eat oil.

Between the water-intensive nature of ethanol production, its relative inefficiency for power generation, compared to petroleum-based products, and the devastation of more land to plant corn for ethanol, the green lobby and its citizen-followers are likely to wake up to an environmental mess sooner, rather than later.

Then there's the inflation in food costs that will result from this switch of a major consumable, corn, from foodstuff to auto fuel.

Hitting voters hard in their wallets is never a good way to secure their long term support for a still-unproven 'crisis,' i.e., scientifically proven, human-caused global warming.
