Best for the environment - hybrid or Hummer? PDF Print E-mail

Some interesting arguments about the total cost of environmental factors of hybrids - maybe the anwswer isn't as intuitive as we might think.

But despite all these drawbacks, hybrids are at least better for the environment than say….. a Hummer, right? Nope.

There is some truth to this, but judging from the other articles on the site, methinks they may have a bit of a right-wing bias. Once hybrids become a larger part of total cars sold (which will happen), the cost will swing to their favor. Meanwhile, this makes for a good bar bet.

From the article:

Comparing this data, the study concludes that overall hybrids cost more in terms of overall energy consumed than comparable non-hybrid vehicles. But even more surprising, smaller hybrids' energy costs are greater than many large, non-hybrid SUVs.

For instance, the dust-to-dust energy cost of the bunny-sized Honda Civic hybrid is $3.238 per mile. This is quite a bit more than the $1.949 per mile that the elephantine Hummer costs. The energy cots of SUVs such as the Tahoe, Escalade, and Navigator are similarly far less than the Civic hybrid.

As for Ford cars, a Ford Escape hybrid costs $3.2 per mile – about a third more than the regular Escape. But on the whole, ironically enough, the dust-to-dust costs of many of the Ford non-hybrids – Fusion, Milan, Zephyr – are not only lower than comparable Japanese hybrids – Prius, Accord -- but also non-hybrids – Seville, Civic.

Spinella's finding that a Hummer on the whole consumes less energy than a hybrid than even some smaller hybrids and non-hybrids has infuriated environmentalists. And on its face it does seem implausible that a gas-guzzling monster like a Hummer that employs several times more raw material than a little Prius' could be so much less energy-intensive. But by and large the dust-to-dust energy costs in Spinella's study correlate with the fanciness of the car – not its size or fuel economy -- with the Rolls Royces and Bentleys consuming gobs of energy and Mazda 3s, Saturns and Taurus consuming relatively minuscule amounts.
