CMU study finds that coal retirement is needed for EVs to reduce air pollution

Green Car Congress

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.

Univ of Toronto study details impacts of interaction between driving patterns and electricity generation for WTW energy use and GHG emissions for PHEVs

Green Car Congress

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).

China’s New Breeder Reactors May Produce More Than Just Watts

China is in the middle of a big buildup of its nuclear-weapon arsenal,” says Frank von Hippel , a physicist and nuclear-policy expert at Princeton University. “My My belief is that one of the purposes of these reactors is to produce weapons-grade plutonium for that buildup.”.

CMU study finds controlled EV charging can reduce generation cost, but at greater health and environmental costs depending upon the generation mix

Green Car Congress

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. A paper describing the work is published in the ACS journal Environmental Science & Technology. other parts of the US and the world could be different.

CMU county-level study shows plug-ins have larger or smaller lifecycle GHG than gasoline ICE depending on regional factors

Green Car Congress

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).

Over three decades later, Martinson reinvented himself, earning an Executive Master of Sustainability Leadership (EMSL) from the School of Sustainability at Arizona State University. All these years later, Martinson and his wife both drive Teslas and their daughter drives a Chevrolet Volt PHEV. Paul Hirt, became a close friend.

Lean Software, Power Electronics, and the Return of Optical Storage

Cars That Think

It’s very similar to the infrastructure for electric cars because the idea, ultimately, for electric cars is that you also are revamping your grid to facilitate, whatchamacallit, intermittent renewable energy sources, like wind and solar, because having an electric car that runs off a coal-fired power plant is defeating the purpose, essentially.
