Holiday Travel Plans and a Letter from a Reader

I will be traveling from December 16th until January 13th with intermittent Internet access. During this time, I hope to put up some posts covering the year in energy, my $1,000 bet on oil prices (which I think I will win by the skin of my teeth), finalize my ethanol FAQ, and take a look back at my resolutions for 2007. I probably won’t cover This Week in Petroleum during this time, as I am unlikely to be around a computer when the report comes out. I may also pull up some interesting mail from readers that I have gotten from time to time and post the exchange from a few of those. In fact, I will go ahead and… Continue»

Wisconsin Tops Minnesota

This is a guest entry from Gary Dikkers who explains that Minnesota and Wisconsin are near twins, except in the category of fuel economy. —————————— One of my cars is a 1999 GMC Sonoma light pickup truck. Since I got my first driver’s license, I’ve always kept track of miles driven, fuel used, and computed my fuel mileage. About four years ago I started to notice that whenever I put E10 in my Sonoma my mileage dropped. So I started doing tests — deliberately running the fuel tank to near empty, then filling up with either E10 or straight gasoline, and comparing results. My Experience Using E10 Time after time, I have arrived at consistently similar results: When I burn… Continue»

A Seamless Transition to a Post-Fossil Economy?

I am going to be covered up through the weekend, but there have been some good discussions down the page that I want to bump up as stand alone posts. One is a discussion of the situation in Venezuela, and whether the IOCs were/are exploiting the people there. I will pull bits of that up at some point, but it will take more time to extract the relevant portions. But, following my most recent essay, reader Benjamin Cole made some comments that are worth bumping up for discussion. I won’t have time until after the weekend to address them in detail, but maybe other readers would like a crack. And maybe some will agree with his assessement. Below are the… Continue»

Mark Jacobson Responds to Vinod Khosla

Following the previous response by Vinod Khosla, I sent a link to Professor Jacobson and asked if he had any comments he wanted to make. I received the following, along with permission to post it: Thanks for your email. With regard to the comment that Khosla stated publicly my study was funded by Exxon Mobil, this was reported to me by a student who was at his talk at the Business School at Stanford. The student was the one who asked him the question what he (Khosla) thought of the study at Stanford about ethanol health effects and who told me of the response. I never solicited this information from the student nor even knew Khosla was giving a talk…. Continue»

Vinod Khosla on Mark Jacobson

Note: In the interest of fairness, I will post a response from Mark Jacobson tomorrow. In response to my recent essay, Vinod Khosla and The Truth, I got a response from Mr. Khosla in which he said that my source had not reported the facts accurately. Mr. Khosla and I ended up exchanging over 20 e-mails over this (we also covered a lot of old ground, and some of the e-mails were very frank). Mr. Khosla’s response was “off the record”, but I told him I would be happy to let him respond on the record. After cobbling together a response from various e-mails, I sent it to Mr. Khosla to make sure it accurately represented his position. He made… Continue»

Algal Biodiesel: Fact or Fiction?

The following is a guest post by John Benemann. John has many years of expertise in biomass conversion, and previously co-wrote a guest piece on cellulosic ethanol. On the subject of biodiesel from algae, he literally wrote the book. I originally wrote an article over a year ago in which I mentioned the potential of algal biodiesel. I still believe, as I did then, that biodiesel (or more broadly, renewable diesel) is a far superior fuel to ethanol for reasons I outlined in that essay. However, over the past year, the more I learned about the prospects of biodiesel from algae, the more it started to look to me like cellulosic ethanol: Technically feasible? Yes. Commercially feasible? Nowhere close, and… Continue»

TDP: What Went Wrong

I am still working on an essay on butanol, pentanol, and higher-chain alcohols, but it has been really difficult to find the information I am looking for. (But I have figured out why bio-butanol has not taken off). Regardless, I hope to complete it in a few days. In the interim, in response to my TDP essay, I received a comprehensive e-mail from a reader who provided some very specific details on what went wrong. He included a presentation in which he referred to several slides, and I will pull those out and post them so the references are clear. I will also insert some comments in the text [like this]. ————————————— Robert, I enjoy your blog quite a lot…. Continue»

Prop 87: A Reader Responds

Below is a response from reader Earl Killian, who lives in Silicon Valley. Earl sent me an e-mail a couple of days ago in response to my August essay on Prop 87: California’s Proposition 87 It is getting close to election time, so this is a good time to revisit the issue. Besides the entry above, previous entries on Prop 87 are: More on California’s Proposition 87 Prop 87 Interview Addressing Proposition 87 Criticisms Breaking Down Prop 87 Another Khosla Critic Wow. I have written on that a lot more than I thought (although the 3rd link in the list is a pro-87 guest essay). Anyway, I thought Earl made some very good points in his e-mail, and instead of… Continue»

Fan Mail – Part II

Now, for the second installment – Jim Paris’ over the top rant in which he ignores everything I have been telling him – followed by a response to the points he raised. I did send him a direct e-mail response prior to writing this one, but I basically just blasted him for the willful ignorance he displayed in his response. I offered to address his points provided he gave me permission to post the exchange, but told him I was finished doing this solely for his benefit. Ultimately, after he said “no” to posting the exchange, I decided to post it anyway. An Analogy However, I still hope that Jim can learn something. If he doesn’t learn anything else, I… Continue»

Fan Mail – Part I

Warning: If you send me an e-mail, in which you proceed to waste my time and make a fool of yourself, consider it fair game for publication. When I get these e-mails, I have always asked permission for publication, but I will no longer extend that courtesy for flagrantly rude, over-the-top e-mails, like the exchange I am about to highlight. If I am going to waste time on this sort of stuff, others should be able to learn from the exchange. I don’t have time to answer too many e-mails in detail AND post essays to my blog and The Oil Drum. I get all sorts of e-mails, but inevitably get some that disagree with my position on some point… Continue»
