According to a new Rand Corporation study, diesel and hybrid cars and light trucks provide more societal benefits than gas or E85 vehicles. For the antiRands out there, listen up for a minute.

The research forecasts the benefits and costs of three alternatives to the gas-powered internal combustion between 2010 and 2020. Advanced diesel and hybrid technologies showed well. E85 did not. Comparisons were made for three vehicle types: a mid-sized car, a mid-sized SUV, and a large pick-up. The cost-benefit comparisons were made for individual consumers, and for society, on a per-vehicle basis over the life of the vehicle. The results placed advanced diesel first, followed by hybrid, gasoline, and last of all E85.

Consumer considerations included technology costs, fuel savings, mobility, and performance. Societal considerations included tailpipe pollutants, greenhouse gas emissions, and energy security costs (from greater dependence on expensive and unstable foreign oil supplies [not to mention oil spills…]). The report noted that if the cost of hybrid falls significantly, its benefits will likely equal or exceed the diesel. It also noted that E85’s dismal results are the result of the high costs of producing the fuel.

Thank you!

We didn't know what to expect when we told you we needed to raise $400,000 before our fiscal year closed on June 30, and we're thrilled to report that our incredible community of readers contributed some $415,000 to help us keep charging as hard as we can during this crazy year.

You just sent an incredible message: that quality journalism doesn't have to answer to advertisers, billionaires, or hedge funds; that newsrooms can eke out an existence thanks primarily to the generosity of its readers. That's so powerful. Especially during what's been called a "media extinction event" when those looking to make a profit from the news pull back, the Mother Jones community steps in.

The months and years ahead won't be easy. Far from it. But there's no one we'd rather face the big challenges with than you, our committed and passionate readers, and our team of fearless reporters who show up every day.
