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. UC stands for uncontrolled charging and CC stands for controlled charging.

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

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.

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).

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

is building two fast-neutron nuclear breeder reactors, the first of which is slated to connect to the grid in 2023, the second in 2026. 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 It is anything but.

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.

Over three decades later, Martinson reinvented himself, earning an Executive Master of Sustainability Leadership (EMSL) from the School of Sustainability at Arizona State University. We had a conversation about EVs, and I asked him if the grid would ever be ready for all the EVs that would eventually be on the roads,” Martinson remembered.

Revenge of the Electric Car

The Chevrolet Volt and the Nissan Leaf will lead the way, with others manufacturers including Ford, Mitsubishi, Toyota, and Tesla planning to introduce their electric cars sometime between 2011 and 2012. Robert Paaswell, director of the University Transportation Research Center, would probably agree. On Volt and Leaf.
