If you currently mean different European states, then the big problem here are the taxes which countries push on the fuel itself. As you probably know, Europe is known for being “green”, so they think that they do a huge favor to the world by selling fuel expensively. Fortunately, where I live, we have been able to keep the taxes under control and although they were raised a year ago to meet EU minimum, we’re still quite okay. The fuel prices could go down even more but probably just the fuel companies themselves wan’t to earn some more profit. They seem to be decreasing the price slowly nearly every week. Well, better slow than nothing!
