As states continue to use less coal for electricity, driving electric vehicles becomes even cleaner

Green Car Congress

Battery electric vehicles are only as clean as the energy source used to generate the electricity that powers them. These results indicate that coal and oil are the energy sources leading to most emissions, and that hydro, wind, and nuclear are the energy sources leading to least emissions. Natural gas. from coal.

Carbon emissions from generating electricity for electric vehicles vary greatly across the individual US states

Green Car Congress

by Michael Sivak, Sivak Applied Research The overall advantage of battery electric over gasoline vehicles, in terms of well-to-wheels emissions of greenhouse gases, has been well documented. However, the emissions of electric vehicles depend greatly on the energy source used to generate the electricity that powers them.

U-M study: When, where, how electric delivery vehicles are charged has big impact on GHGs

Green Car Congress

In 2019, Amazon announced plans to obtain 100,000 electric delivery vehicles. UPS has ordered 10,000 of them and FedEx plans to be fully electric by 2040. Charging practices that shorten a battery’s lifetime will lead to early battery replacement, adding to the total greenhouse gas emissions associated with that vehicle.

UMTRI study shows wide global variability in GHG emissions from operating an EV

Green Car Congress

A team at the University of Michigan Transportation Research Institute (UMTRI) study has assessed the relative amounts of greenhouse-gas emissions from driving a battery-electric vehicle (BEV) compared with greenhouse-gas emissions from driving a traditional gasoline-powered vehicle in different countries of the world.

MIT, Ford researchers find lightweight conventional vehicles could have lower lifecycle GHG impact than EVs depending upon location

Green Car Congress

Researchers at MIT and the Ford Motor Company have found that depending on the location, lightweight conventional vehicles could have a lower lifecycle greenhouse gas impact than electric vehicles, at least in the near term. Their paper is published in the ACS journal Environmental Science & Technology. —Wu et al.
