"Diesel prices in the U.S. are barreling toward a painful new milestone for the transportation industry: $6 a gallon, a surge experts said is likely to have ripple effects for consumers as businesses pass on their higher energy costs. The national average for a gallon of diesel on Thursday rose to $5.98, up 61% from $3.71 a year ago, according to data from AAA. Diesel is widely used in trucking and rail, affecting the cost of transporting goods around the U.S., as well as in construction and farming."
