An alarming, and at the same time, reassuring realization is making its way to the forefront of the minds of energy onlookers. The United States has one of the world’s largest oil reserves: trapped deep within the rocks of Colorado, Wyoming, and Utah, as well as Kentucky, Ohio, and Indiana, is an oil shale with deposits estimated at more than five times the size of Saudi Arabia. However, this oil is not readily available. If nature were to take its course, the oil could not be extracted for millions of years.
