As part of an ongoing efficiency and conservation effort, President Obama announced this week that his administration will set higher fuel-efficiency standards for medium- and heavy-duty trucks by March 2016, a move that could reduce dependence on foreign oil, cut fuel costs, and lower consumer prices.
Our global oil system is operating at near capacity—97 percent—which just isn’t sustainable. Because 70% of oil consumption in the U.S. is used for ground transportation, reducing the amount of gas used by vehicles is key to heading off an impending crisis. Boston-based Vecarius, which recently won the 2013 Sustainable America/Greentown Labs Fellowship, is working to tackle this problem by turning vehicles’ exhaust waste heat into energy, technology that can reduce fuel usage in vehicles by 5 to 10 percent. We talked to CEO Steven Casey to learn more about his innovative product.
Cummins Inc. and Peterbuilt Motors recently announced the impressive results of the test of their “SuperTruck,” a tractor-trailer designed to cut fuel usage by half through aerodynamics and a higher-efficiency engine. Under real-world driving conditions, the SuperTruck’s fuel economy was found to be 54 percent higher than a regular long-haul truck, averaging nearly 10 miles per gallon (mpg).
