Study estimates fuel economy improvements to US light-duty vehicles from 1975–2018 saved 2T gallons of fuel, 17B tons of CO2

Green Car Congress

A team from the University of Tennessee and the National Renewable Energy Laboratory (NREL) has the fuel savings due to fuel economy improvements over the past 43 years amount to approximately two trillion gallons of gasoline. Estimated attribution of fuel savings due to fuel economy improvements to light-duty vehicles since 1975.

DOE: in 2018, 27% of new light-duty vehicles in US had fuel economies > 30 mpg

Green Car Congress

In 2018, 27% of new light-duty vehicles sold in the US had fuel economies of more than 30 miles per gallon (783 l/100 km), according to the US Department of Energy (DOE). By contrast, none of the light-duty vehicles produced in 1975 had fuel economy greater than 30 miles per gallon (mpg). In 2018, 2.4%

ORNL researchers use stop-light cameras to reduce fuel consumption of less-efficient vehicles via traffic management

Green Car Congress

Approximately 6 billion gallons of fuel are wasted in the US each year as vehicles wait at stop lights or sit in dense traffic with engines idling, according to US Department of Energy estimates. The team’s first step in February 2018 was to use GRIDSMART cameras to create an image dataset of vehicle classes.
