Electric Car Breakthrough?

There are certain alternative energy technologies that I believe will have an enormous impact on our future. Heading that list is solar energy, followed by wind power, biomass gasification, and possibly cellulosic ethanol. Most alternative energy sources that I think have a real chance to make an impact involve electricity generation. Therefore, in order to really impact the transportation sector, we need to move toward electrifying more of our transportation options. I was recently asked what kind of cars we would be driving 100 years from now. Without hesitating for a second, I replied “Electric cars.” A key reason we aren’t driving them now is that the range and convenience is not what we are accustomed to with internal combustion… Continue»

No Price Manipulation

I have lost track lately of the number of people who think oil companies are deliberately dropping prices in order to influence the election. I have close ties to the product pricing group, and I can tell you that these assertions are ludicrous. In fact, I mentioned these conspiracy theories this morning in a meeting, and everyone had a good laugh. But one person asked “Don’t people understand how oil and gas are priced?” The answer is, “No, they do not”, so we have this disconnect. I have intended to write a post to address those who insist that gas prices are tied to the election, but I know that there are people who distrust me merely because I work… Continue»

Breaking Down Prop 87

Introduction California’s Proposition 87 promises to reduce oil consumption in California, at no expense to the consumer. I am quite sympathetic to the goal of reducing petroleum dependence. This is a goal to which we should all aspire. But I have my doubts that the promises being made by the Proposition 87 campaign can be kept. I also dispute many of the claims made by the Prop 87 proponents. Finally, I have a problem with the way the oil industry is being portrayed in order to win support for this measure. While I do not intend for this to be a point by point rebuttal of Ana Unruh Cohen’s recent essay in support of Prop 87, I do intend for… Continue»

Venture Beat Article

A while back I was contacted by a reporter from Venture Beat regarding my criticisms of Vinod Khosla. A back and forth e-mail exchange ensued between the reporter, Mr. Khosla, and myself. That exchange has been documented in a story at Venture Beat: The Oil Drum Debate, Round 1 There were 3 issues in question during this particular exchange: 1). The energy balance of gasoline versus ethanol.2). Whether Brazil had displaced 40% of their petroleum with ethanol.3). Whether ethanol is cheaper to produce than gasoline. When reading through the exchange, I think you will note how Mr. Khosla has difficulty answering the questions put to him. Even in the case of Brazil, in which he has made claims that are… Continue»

Addressing Proposition 87 Criticisms

Background Voters in California will go to the polls in November to decide the fate of Proposition 87, also known as the Clean Energy Initiative. However, the ramifications of this proposition have the potential to be felt nationwide. I have previously written a pair of essays on Proposition 87 that you can find here and here. My position is not so much that I am against Prop 87, and I am certainly not against the intent of Prop 87. But I do have concerns about the proposition, which are explained in my previous essays. In response to my essays, Dr. Ana Unruh Cohen, former Rhodes Scholar and the Director of Environmental Policy at the Center for American Progress, asked if… Continue»

Postscript with Wang and Khosla

I think the thread on efficiency of ethanol versus gasoline left a lot of things hanging, and there have been some communications with Dr. Wang and Mr. Khosla since then. So, I wanted to more or less close the book on this and share those communications. I don’t want to spend another 300+ posts arguing about efficiency, but I do want to let the readers know how this all turned out. Dr. Wang was clearly miffed about my usage of “sleight of hand.” While I do not consider usage of this phrase insulting, I felt like the right thing to do was to apologize since Dr. Wang took offense. So, I e-mailed back to Dr. Wang, Tom (who never again… Continue»

Integrated Bioenergy Center

Believe it or not, I was working on this post before I got massively distracted by the efficiency questions surrounding ethanol and gasoline. To some, I may seem to be a bit of a Jeckyll and Hyde with respect to ethanol. One day, I am bashing it. The next day, I am endorsing it. So what’s the deal? I fully acknowledge the need to move away from fossil fuels, but most grain ethanol in this country is primarily recycled fossil fuels. I object to taking fossil fuels, converting them to ethanol, subsidizing the ethanol not on the basis of energy “created”, but instead on a per gallon basis, while mining our topsoil in the process. However, ethanol does not have… Continue»

Battling with the Critics

Just when I thought I was out, they pull me back in. I am trying to spend more time writing on topics other than ethanol. But I get a lot of e-mails on that subject, and often have 3 or 4 mini-debates going on at a time via e-mail. I just finished a debate involving a government official and some big names over the energy balance of gasoline versus ethanol. There still seems to be a lot of confusion surrounding this issue, so I asked for permission to publish the exchanges. I was reluctantly given permission, provided I deleted the personal information from the government official (name and government agency). The exchange involved myself, a government official that I will… Continue»

More on California’s Proposition 87

Previously, I wrote an essay describing exactly why California’s Prop 87 will raise gasoline prices for Californians: California’s Proposition 87 Yesterday, the Yes on 87 campaign put out a strange press release. It read in part: LOS ANGELES, Aug. 24 /PRNewswire/ — The following memo was sent to the CEO’s of ExxonMobil, Shell, Chevron, and other oil companies opposing Prop. 87: TO: CEOs of ExxonMobil, Shell, Chevron, and other oil companies opposing Prop. 87 FROM: Chad Griffin, Campaign Manager, Yes on 87 RE: Staffing Changes at No on 87 The full page New York Times ad run yesterday by your national political operation — the American Petroleum Institute — highlighted a messaging problem within your California campaign against Proposition 87….

Guest Post on Cellulosic Ethanol

The following is a guest post by Don Augenstein and John Benemann. They have many years of expertise in biomass conversion. This essay is in response to Vinod Khosla’s recent posting on ethanol. In my opinion, it is an excellent essay. First is the introduction by Don Augenstein. Introduction This post presents a perspective on ethanol from lignocellulose by my friend and co-worker, John Benemann. We have worked on, and been immersed in, biofuels and analyses of fuels from biomass processes for over 3 decades. We are to substantial degrees biotechnologists, as well as chemical engineers and have successful processes going today (methane from wastes. You can google Don Augenstein). We have worked long and hard on biofuels for entities… Continue»
