The average retail price of a gallon of diesel fuel in the United States rose 2.2 cents to $2.915. It is the highest price since July 6, 2015. Speculation is that production cuts will continue into 2018 after a meeting of OPEC countries this month. California ranks the highest at $3.610. In contrast, the Gulf Coast Region is again the most economical at $2.697 per gallon. With these higher prices, fleets are looking at alternatives to reduce their costs. Some reefer fleets have turned to battery-powered refrigeration units with solar panels. With no end in sight, everyone will have to be creative to solve this problem.
