Well theres nothing the US Government or private industries in the United States can do to lower the gas prices significantly in the short term. The gas companies such as Exxon Mobil could cut their profit margins, but that would only lower the price of gas by 20-30 cents assuming they took no new profit which meant no more investing in new oil fields. In fact, the profit margins in the oil industry are much lower than similar businesses in the United States, but people automatically assume they are higher because of the “record profits”.
Therefore, the problem is the price of crude oil. This can be affected by political instability in the Middle East, but the real problem is that demand is almost the same as supply. The Saudis have said they are going to open up some new oil fields and export more oil, which combined with decreased demand in the US will drive prices down next year. But we will run into this problem in a few years when demand starts rising again and passes supply. At that point, its unclear if the Saudis will be able to increase their supply any more. There are new oil fields in the oceans, but some of these would cost $200 a barrel just to break even, and crude oil at this point is $143. We could also drill in the United States, but it would take ten years for the first oil to reach the pipeline.
So in short, high gas prices are here to stay in the long run. Prices will fall late this year and into next year, and may not spike as high next summer, but after that I only see prices going higher.
