Over the past few years, the U.S. fracking boom has taken a great many people by surprise. Companies have been producing so much oil and gas that it’s now putting a strain on America’s energy infrastructure.
Case in point: The Energy Information Administration recently put out a report showing that U.S. transport of crude oil by rail, truck, and barge has soared by 57 percent between 2011 and 2012, surpassing 1 million barrels per day.
Out in North Dakota, for instance, companies are now producing far more shale oil from the Bakken formation than existing pipelines can handle. So the producers are instead shipping it by rail to the refineries that will turn it into gasoline and other fuel.
