Report by the University of Michigan Transportation Research Institute indicates EVs are much cleaner than conventionally powered vehicles. Joseph Szczesny reports.
Claims that electric vehicles won’t help reduce harmful emissions are flawed and, instead, evidence suggests EVs can have a major impact on reducing the pollution traced to vehicles used in everyday life, a University of Michigan study finds.
The report prepared by Michael Sivak and Brandon Schoettle of the university’s Transportation Research Institute indicates that, based on a review of so-called “well-to-wheels” studies that take into account both the sources and production of electricity and the fuel used in internal-combustion engines, EVs are substantially cleaner than vehicles with conventional powertrains.
“Based on the average mix of renewable and nonrenewable electric power sources in the US, the average well-to-wheels (greenhouse-gas) emissions for battery-electric vehicles (BEVs) is the lowest, at 214 grams per mile,” the researchers say. “The corresponding values for two different plug-in electric vehicle implementations, PHEV10 and PHEV40, range from 253 to 278 gpm, respectively.
“Gasoline-powered vehicles produce the most GHGs per mile, ranging from 356 to 409 gpm, depending on the specific type of ICE (direct-fuel-injection versus conventional port-fuel injection, respectively), Sivak and Schoettle say. This article first appeared in WardsAuto.
