An interview with Greasecar founder Justin Carven

Justin Carven. In the span of just two years, Justin Carven invented the first waste-oil conversion kit for diesel engines, graduated from Hampshire College, drove a vegetable-oil-fueled van across the country, and started his very own company. Six years later, Greasecar Vegetable Fuel Systems is selling so many conversion kits that Carven is talking about […]

Toward a community-owned, decentralized biofuel future

President Bush visits the Virginia Biodiesel Refinery in 2005. Photo: whitehouse.gov Biofuels won’t single-handedly solve the climate crisis, nor will they deliver energy independence. But a base of widely dispersed, farmer- and citizen-owned biofuel plants can displace significant amounts of fossil fuels — while also building local economies. What follows is a strategy for tweaking […]

To fulfill its environmental promises, biofuel policy needs a kick in the pants

As war simmers in the Middle East and oil prices rise along with global temperatures, Midwestern farmers and politicians aren’t the only ones banging the drums for biofuels. Now big-time investors, security hawks, environmentalists, and even George W. Bush have joined their ranks. But is environmentally responsible bioenergy a real possibility, or are we bio-fooling […]

Silicon Valley investor Vinod Khosla chats about the promise of ethanol

Venture capitalist and ethanol booster Vinod Khosla. Billionaires are piling onto the biofuels bandwagon. Bill Gates is doing it. Richard Branson is doing it. The Google guys are doing it. Less well-known is the billionaire who kicked off the whole trend: Vinod Khosla, a cofounder of Sun Microsystems and former partner with Kleiner Perkins, the […]

An interview with David Pimentel

Any worthy idea can withstand and even be improved by naysayers; scolds and skeptics play the useful role of pointing out obvious flaws. The biofuels industry has no more persistent, articulate, and scathing critic than David Pimentel, professor emeritus of entomology at Cornell University. David Pimentel.

Three perspectives on the biofuels debate

Imagine how amazing petroleum must have seemed back when it was an emerging alternative fuel in the U.S. Drill a hole in the ground in some parts of Texas and Pennsylvania, and rich black stuff would come gushing up, loaded with energy. What could possibly be the problem with such bounty? In some quarters, biofuels […]

Flex-fuel vehicles greenwash Detroit’s SUV addiction.

David mentioned something about it when it came out a couple of months ago, but as Grist wraps up its first week of biofuel coverage, it's worth pointing to again: after much testing and comparing, Consumer Reports finds the whole live-green-go-yellow, E85 thing pretty much a sham.

As Grist readers will know, the government gives automakers a credit against their mileage requirements for every flex-fuel vehicle (able to run on ethanol, gas, or a mix).

CR's conclusion: Detroit is using it a lever to help it churn out more gas-guzzling SUVs, and the policy is working to increase fossil fuel consumption, not stem it.

The most depressing finding, for me: the greenwash appears to be sticking with the general public:

A handy biofuels glossary, and videos to boot

With all the talk of biofuels swirling around, things can get a bit confusing. So we’ve put together this handy glossary for your reference. Now you can pontificate at cocktail parties with the best of ’em. And just to keep you awake (yeah, we remember second grade too), we’ve included some explanatory videos thanks to […]

Richard Branson chats about embracing ethanol and slashing airplane emissions

Does a music mogul who signed the Rolling Stones and Janet Jackson have what it takes to make a pop star out of biofuels? Sir Richard. Earlier this fall, publicity-chasing British entrepreneur Richard Branson made a $3 billion bet that he could do just that — and help solve the climate crisis to boot — […]
