Taking Freight Trucks Electric Would Have Big Economic and Environmental Benefits for India
Diesel-fueled freight trucks play an outsized role in producing India’s total greenhouse gas and air pollution emissions. While the country has promoted policies to transition to electric vehicles for public transportation buses and cars, batteries that can power such large trucks have been too heavy and expensive to make their electrification possible. A new study shows that advances in battery technology and dramatically decreased battery costs in recent years have changed that. With the right policies and incentives, battery electric trucks would be more affordable to operate than diesel, and India could become a world leader in producing electric vehicles.
