Are diesel vehicles only the methadone of gasoline addiction? LA Times writer says so.

Who gives a damn about the LA Slimes?

I read the Orange County Register ;)

yet another misleading headline!

the author is saying that ALL SUVs (no matter what kind of engine) are not green because of their sheer size and poor fuel economy RELATIVE to smaller vehicles.

and i have to agree. if environmental impact is your top priority you need to buy a small vehicle, it's that simple.

The future of diesels runs parallel to the future of gasoline engines, and it doesnt look so good. Diesels have just made a huge leap in cleanliness to match their efficiency (which should be commended). This advancement comes after 100 years of development. Gasoline engines, with variable valve timing, overhead cams, etc hit a huge peak in their development since the 80s. These engines, gasoline and diesel, are not going to get exponentially better. But the supply of fuels will continue to dwindle, while the demands from developing countries will increase. Therefore an alternative to fossil fuels is the only answer.

For now, hybrids represent a real advantage. We are only starting the second decade of hybrid engines, gen 3 for Toyota, I believe. As they progress, the engines will rely less on their gasoline parts, and more on their electric parts. This is a sustainable answer, and a good transition to EVs or hydrogen vehicles. We need to move away from as much of a reliance on fossil fuels as possible. Diesel does not wean us off the dino juice, and so they are not the answer.

We ought to tax the hell out of those driving vehicles (more like industrial equipment) weighing more than 4,000 lbs. Wake up folks, we're slowly (I may be too optimistic here) running out of crude. That guy/gal next to you in the giant SUV is using up your gasoline allotment that you'll need in a few years.

I've put cars and environmental friendliness on the back burner for me - my new campaign is to save the rainforest!! The destruction of the rainforest accounts for over 18% of ALL CO2 emissions in the world! All transport accounts for 14%!

SAVE THE TREES, don't buy stuff with palm oil in it or buy bio-fuels, as people cut down forests to plant palm oil plantations to sell to cosmetic companies and bio-fuel makers!! It's a horrible horrible irony!!!
Plant a tree in your backyard, but don't drive to the store to buy it!!!

I don't think that anyone is saying that Diesel engines are the final answer to any of this. No more than replacing a light bulb or two in your house is going to make a huge impact on your electric consumption. Put enough diesels and/or Hybrids on the road however, and we will see a significant reduction of fossel fuel consupmtion which is what we all want.

These are also the only marketable options right now. Distribution of fuel is already in place and performance of the vehicle does't really suffer that much.

Until someone figures out how to produce Hydrogen and/or electricity cheaply enough and build the infrastructure to support these new systems, we will be stuck with these solutions for the forseeable future. It doesn't matter how many laws we pass, or how committed you are to the green cause, the math is still the math.

There needs to be some sort of breakthrough in the production cost of Hydrogen to make any switch even feasable. There also needs to be some work done in the area of battery technology and the disposal and recycling percentages. Everyone is working on these things but the math still doesn't add up yet. There are also safety concerns with Hydrogen storage in a vehicle. I'm still not completely comfortible driving around with the equivilant of a brick of C4 in my trunk. Put enough cars on the same street with all that explosive power and you kind of well, get the picture. Park a few hundred of those things in the basement parking garage of your nearest office building and see how comfortable you feel.

The answers will not come overnight and may not happen for decades to come. We are however, at least working on it.

"In the US however, the fuel prices are almost completely governed by the oil companies!"

Wrong. The oil companies do not have some secreat lair containing a dial with which they control teh prices- it does not work that way. Dr Carol Dahl, head of the Department of Economics and Business at the Colorado School of Mines recently conducted a study for the-I can't remember if she said DOE or WTO-and found that recent jumps in prices can be entirely explained by the market. She incidentally is no friend of the oil companies.

The oil companies are not withholding production in order to drive the price up either- they are producingas much as possible. The reason for this is simple- the futures market is in backwardation. Prices are anticipated to fall and the thing that people who have never taken a natural resource economics class often miss is that firms producing under a fixed stock constraint inter-temporally optimize their production to maximize net present value. The only way in which companies would withhold production is when the prices are anticipated to rise at a rate greater than r, the opportunity reinvestment rate. If you have any doubts about anything I have just said the works of Hotelling and Nordhaus are excellent. The point is that they don't set the price, the price is an input from which their production is determined.

There is also a great book by Dr. John Tilton (Educated at Princeton and Yale and the former occupier of Carol Dahl's position) called "On Borrowed Time? Assessing the Threat of Mineral Depletion".

I understand that you may be refering to a sort of market buffer in the form of taxes which can be releived in order to decrease the bruden on the consumer. That won't necesarily do anything to fix the problem in terms of substitues and the market. Removing the taxes pushes is not necessarily bad in the short term. But that type of activity can be destructive when it moves from that to setting price caps. There is a book called "The Doomsday Book" as I recall and the only times when when scarcity has lead to a ciilization destroying catastrophy is when government has stepped in and set a price cap.

Every day I see brand-new SUV's and pickups. You can tell them by the cardboard temporary license plate tags. It just amazes me. The first tank of gas is $100 and they are saying, "yes, I will pay this."

How come nobody has mentioned the Fuell Cell option ?

With the FCX model honda has shown that Fuel Cells are a very available option so i will venture a guess that within the next 10 ears you will see huge improvements in the efficiency and performance of this Technology, and the Infrastructure around the supply of hydrogen.

It's not commonlpace yet, but hydrogen is available to the public in large urban centres.
http://www.h2stations.org/
There are 5 in and around Toronto which is perfect since that's where most sales will be initially.

One must also consider that ALL diesels are 100% renewable fuel ready right out of the box. Unlike gas-powered cars that must be designed with a special manufacture to accept an inferior alternative fuel, diesels can readily accept any blend of biodiesel or renewable diesel fuel with no modification and only a few precautions. Moreover, biodiesel and renewable diesel fuels contain much more energy density than gasoline alternatives and consumers lose little if any fuel economy while reducing petroleum consumption even more.

For example, I drive my 2006 Jetta TDI exclusively on B20 blend (20% biodiesel blended to 80% diesel fuel). I maintain 44 mpg, average and there is no sacrifice of any kind. The gas Jetta gets 26 mpg (combined cylce, EPA estimate). Buying B20 nets me no extra premium at the pump; no extra precautions; no maintenance issues, and no difference in performance or fuel economy. I Just drive up; pump; and pay. That's it. Everything else is the same except less hyrdocarbons, SO2, CO, and CO2 are being emitted from the tailpipe; and 19% less petroleum is being consumed. And this reduction in petroleum is counted after considering that the TDI gets most people about 50% better fuel economy than standard Jetta owners.

I know, there is biodiesel made from palm oil, but most in the U.S. comes from soy oil; and the potential of algae could net us 20,000 gallons of oil per acre for energy. Even with palm oil, it does not all come from deforestization. Most of Europe's biodiesel comes from rapeseed (canola). The production facilities are cheap to build and operate, and for every energy input for biodiesel, 3.1 units of energy are produced. Biodiesel is nontoxic, nonhazardous, and has twice the flashpoint as regular diesel fuel. Lifecylce CO2 is reduced 78% according to the DoE.

Next someone will come on and state all the limitations regarding worldwide use of renewable fuels, but I'm not claiming that renewable diesel fuels are a cure all or that diesel vehicles are a silver bullet, however, I am stating the obvious: Diesels, together with blends of renewable diesel fuel blends, can save us petroleum and simultaneously reduce greenhouse gases far beyond where we are now with 21 mpg, gas-powered cars. Does this mean we should not continue to move forward towards hybrid technologies and electric cars? No. But this also doesn't mean we should ignore a technology that has already a huge infrastructure in place that could start saving us millions of barrels of oil per month. That technology is diesel engine technologies for cars. Diesel technologies should not rival electric hybrid technologies, because diesels can be electric hybrids as well. The only rivalry is between spark ignition and compression ignition. And as long as we are building cars that are powered by internal combustion engines, we might as well use the most efficient ICEs on earth, and those are diesels!
