Freight System Efficiencies - a US perspective
With heavy truck fuel efficiency standards in place in the USA, the American Council for an Energy Efficient Economy (ACEEE) has decided to explore energy savings opportunities in the freight system more broadly.
The ACEEE's new report, Energy Efficiency Potential of the U.S. Freight System: A Scoping Exercise, compares the findings of five recent studies to explore what energy savings estimates have been identified.
The studies generally found more savings potential from vehicle technology improvements (10 to 23 per cent) than from combinations of system efficiency approaches (0 to 18 per cent), such as shifting to less energy-intensive freight modes, improving logistics and optimizing routing.
The analysis also considered global supply chain studies to explore its relevance to broader efficiency strategies. The supply chain studies found considerably greater potential for savings from freight system efficiency improvements (12 to 37 per cent, or 0.5 to 1.7 million barrels per day of oil in the USA) than the transportation studies found.
In particular, the savings they attributed to approaches such as expanding home delivery, optimizing speed and increasing load factor were quite high. The supply chain studies also considered prospects for moving the production of goods closer to markets, though they differed on whether this would lead to a net reduction in energy use.
