Thanks for that link, that does explain some...the first reason however is the hardest to deal with and comprehend~!~
•High worldwide demand for diesel fuel and other distillate fuel oils, especially in Europe, China and the U.S. and a tight global refining capacity available to meet demand.
The government pushed a transition to diesel in some environments such as the trucking industry, advising it would be more economical and cheaper in the long run...this eventually created more demand which now is the number one reason we pay out the ying yang for diesel.
The prices have put more than a few independent drivers out of business with their trucks now parked and rusting~!~
The problem with Diesel (and fuel and/or oil) in general has little to do with demand. Sure they (the government, the oil companies, the refineries, etc) want us to believe that but that's not the case.
Nope. The problem is supply and supply, alone. With "Peak Oil" on the horizon (whether true or not), record profits over the last few years, and little to no government intervention why would anyone in the oil or fuel business be compelled to produce (read: supply) more? Instead, they will produce less, making the value go up per volume and thus profits soar.
It's simple, really. If the cost of producing a barrel of oil is x. I sell those barrels for x*2. If I can control supply (read: limit production) and thus increase the demand, I can then ask for more than x*2 or x*3; even though my production costs haven't increased a penny. Can we say hello profits?
Now, granted if everyone stopped buying gas (or oil), they would (have to) practically give it away. Unfortunately, this isn't mayonnaise or a loaf of bread that we can boycott. This isn't a particular crop, cigars, or merchandise. This isn't the outsourcing of telephone support and IT. This is something that has so much infrastructure tied to it that it costs more up-front to get out of, in the form of flex-fuel or alternative fuel vehicles.
Maybe, I'm over-simplifying things but I still believe our country should be stepping up or own ability to tap into the resources found under our own soil.
