U-M researchers challenge USPS EV environmental study

Green Car Congress

A new University of Michigan study finds that making the switch to all-electric mail-delivery vehicles would lead to far greater reductions in greenhouse gas emissions than previously estimated by the US Postal Service (USPS). An all-electric fleet would reduce lifetime greenhouse gas emissions by 14.7 Earlier post.). Woody et al.

NREL study finds most depot charging could accomodate short-haul heavy-duty electric trucks without upgrades

Green Car Congress

In most cases the existing technology grid can accommodate truck charging at depots. That perception is shifting, and our research suggests that certain short-haul operations can be electrified today with relatively low-power depot charging that won’t overwhelm the grid. 100 kW/vehicle) for the fleets studied.

Study finds all-electric rideshare fleet could reduce carbon emissions, but increase traffic issues

Green Car Congress

Major ridesourcing companies Uber and Lyft have promised all-electric fleets by 2030 in an effort to reduce their carbon footprint. Previously, researchers calculated that rideshare companies’ carbon footprints could significantly decrease by fully electrifying their fleets.

UPS/Greenbiz study identifies motivators and barriers to electric fleets

Green Car Congress

Attaining environmental benefits and lower cost of ownership are driving more commercial fleets to electrify, according to a new study by UPS and GreenBiz. Despite an appetite for electrification, many fleet operators face challenges. —Scott Phillippi, UPS senior director of automotive maintenance and engineering.
