Lots of feelings on this topic...
First there is as Greg says a lack of refining capacity. A big lack. In my area they have closed 2 refineries. This means trucking or rail for the supplies.
The oil sands project has some really needed added investment so it will be a greater supply. But on the subject of local production costing so much well not sure all the reasons in the US but the idiots in Canada allowed Alberta producers to charge as much as world pricing. Hence high prices for their oil now.
As for european and asian markets paying high prices they do things we don't! One is they mostly drive smaller more fuel saving vehicles. Look at M-B offerings in Germany and France and you'll see more Diesels. Same for Renault, Volvo, Ford. Look at the Smart car. Small, great fuel mileage and a small Diesel. By the way Renault offers a van similar to the Sprinter. In Japan and Korea look at the domestic car markets, small vehicles that Americans have rejected for years. But they all get over 30mpg some 40mpg and more.
Biodiesel and ethanol fuel, good choices and yes will help if they change the idea of charging more like they do here. Remember that if they went to a B10, E10 they save 10% of the current oil usage, this leaves more oil for refining. Oh yeah not enough capacity!!! Yes there is the EPA problem of building a refinery and also the NIMBY factor (not in my back yard)!
High prices are here to stay so this means we have to be more into how we can save fuel. Drive at 55 not 65 5-10% savings right there, no idling, use an APU, smooth sided boxes, wheel covers (smooth ones reduce drag}, no extra accessories hanging out in the wind, place them behind the cab or have them open out when stopped, whatever.
Yeah I do follow the slow speed idea and I'm saving fuel $$.
