Two energy-related articles worth your attention:
First, as the price of oil hangs around $66 a barrel oil companies are finding it cost-effective to consider tapping into Colorado oil shale where recoverable deposits are believed to be more than three times greater than what remains in the Saudi Arabian fields. These deposits have been known about for decades but the cost of squeezing the oil out of them was always prohibitive. That no longer seems to be the case.
Second is an article by James Glassman at Tech Central Station which cites the lessons of history by way of warning against slapping a counterproductive windfall profits tax on oil companies. The answer to high prices, Glassman writes, is to increase supply and that can be done by decreasing onerous and unnecessary regulations on the industry which prevent them from drilling for known oil in the Atlantic and Alaska. Regulations also discourage the industry from increasing refining capacity which has really crippled our ability to get petroleum to market even when the supply has been adequate.
