This morning I heard a brief news item on the radio about some guy who has invented a plastic that can be digested by some enzymes and a little water. Process takes about five days and you have biodiesel. Nice way to reduce landfill, and have a good quality fuel. The military is putting millions of dollars into this. |

think the price of diesel will rise with the introduction of the 'new generation' diesels? if a bunch of these flood the market and refining capacity does not change, what do you think will happen?

Replying to: explorerx4 (Apr 09, 2007 6:05 pm) during winter when diesel fuel price exceeds premium-unleaded, i am happy to pay more per gallon as long as that results in lots more mpg and reducing oil imports. (which i think it does) . a possibly related factoid is that diesel cars use a miniscule amount of diesel fuel compared to bigrigs/busses/construction-equipment/etc. i think i've read that that diesel cars/pickups/SUVs in USA use about 0.2% of diesel fuel burned in USA - or less. that's with 3% of US fleet being diesel. so if the fleet diesel percentage triples to 9% , the diesel fuel consumption for cars/SUVs/pickups could go up to about 0.6%. is that enough to affect diesel fuel price? i don't know, but i'd guess "not much". I understand that a barrel of oil can produce about 30% diesel and 70% gasoline. so it seems to me that we ought to optimize the US fleet percentage somewhere in that ballpark, considering also the weighted average of gallons-used & mpg, all that stuff.

Replying to: elias (Apr 10, 2007 6:17 am) While I agree with your reasoning and advocation of policy, here are some factoids: barrel of oil = 42 gals gasoline production 19.3 gals =46% diesel production 9.83 gals = 23.4% the remaining 30.6% finds its outlets in a host of different markets and applications. (another discussion) http://www.sanjosegasprices.com/crude_products.aspx Most folks do NOT understand the ramifications of these ratios. Additionally, use of diesel imparts a 20-45% gain of fuel mileage. This of course further belies the diesel advantage by a min of 25%. Also it is fairly obvious the whole passenger vehicle fleet fuel delivery system is "finely tuned" for unleaded regular with two so called "profit" padders: mid grade, premium. Upwards of 97% of the passenger vehicle fleet using (unleaded) gasoline. |

Diesel price jump Price of diesel goes up 5 cents a gallon; oil prices drop WASHINGTON (April 9, 2007) — The average retail on-highway price of a gallon of diesel and the price of a barrel of crude oil looked like the opposite ends of a seesaw today with diesel prices riding the higher end of the teeter-totter. The Energy Information Administration of the Department of Energy said the average price of a gallon of diesel rose a nickel to $2.84 a gallon for the week ended April 9, marking the first time since last November that the average price had exceeded $2.80 a a gallon. The average price has increased 42.7 cents a gallon since the week ended January 29, when the average price was $2.413, and has gone up each week. Where and when the upward trend will stop, experts probably don't know, but an upward spiral in late January last year saw the price increase from $2.472 all the way up to over $3 in early August before the price started down again, ending the year at $2.606.
