U.S. Could Cut Fuel Use 50% by 2035

Written by Andrew Williams

A new report by the Massachusetts Institute of Technology (MIT) Energy Initiative predicts that a 30-50% reduction in fuel consumption is possible in the US over the next 25-30 years. Initially, this will be achieved through improved gasoline and diesel engines and transmissions, gasoline hybrids and reductions in vehicle weight and drag. In the longer term, the study concludes that plug-in hybrids and, later, hydrogen fuel cells may begin to have a significant impact on fuel use and emissions.

The report, ‘On the Road in 2035: Reducing Transportation’s Petroleum Consumption and GHG Emissions,’ summarizes the results of an MIT research project that assessed the technology of vehicles and fuels that could be developed and commercialized during the next 25 years.

The research team assessed the effect of new vehicle and fuel technologies on the performance, cost and lifecycle emissions of individual vehicles. It then assessed the effects on the total on-the-road fleet of introducing these technologies using “plausible assumptions about how rapidly they could be developed, manufactured and sold to buyers to replace existing vehicles and fuels or to add to the existing fleet.”
