Electric vehicles charged in coal-heavy regions can create more human health and environmental damages from life cycle air emissions than gasoline vehicles, according to a new consequential life cycle analysis by researchers from Carnegie Mellon University. That’s why the shift away from coal is so important for EVs.

The team from Carnegie Mellon University led by Dr. Jeremy Michalek accounted for regional differences in emissions due to marginal grid mix; ambient temperature; patterns of vehicle miles traveled (VMT); and driving conditions (city versus highway). Toyota Prius PHV PHEV (blended). Toyota Prius HEV. Yuksel et al.

A new study by researchers at the University of Toronto examines the impact of the interaction between driving patterns (distance and conditions) and the mode of electricity generation (e.g., coal, hydro, natural gas) on well-to-wheel (WTW) energy use and greenhouse gas (GHG) emissions of plug-in hybrid electric vehicles (PHEVs).

Results from the study also suggest that with sufficient coal plant retirement and sufficient wind power, controlled charging could result in positive net benefits instead of negative. Small Battery: For this scenario, they modified the base case so that the vehicle fleet is based on the Toyota Plug-in Prius.

A paper by a team from the University of Chicago and MIT suggests that technology-driven cost reductions in fossil fuels will lead to the continued use of fossil fuels—oil, gas, and coal—unless governments pass new taxes on carbon emissions. for oil, 24% for coal, and 20% for natural gas.

the “carbon footprint” of electricity production and use), according to a new study by researchers at Carnegie Mellon University. Under some conditions, the battery electric Nissan LEAF can produce higher emissions than a Toyota Prius hybrid. They compared these vehicles with the Toyota Prius HEV. Credit: ACS, Tamayao et al.

Four years ago, the professor at the University of California at Davis and a team of engineering students created a plug-in vehicle. The university students reversed the roles by combining a more powerful electric motor that went 50 miles without using any gasoline. A typical hybrid has a big gasoline engine and a tiny electric motor.
