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

Green Car Congress

Estimated difference in life cycle GHG emissions (gCO 2 eq mi −1 ) of selected plug-in electric vehicles (2013 Nissan Leaf BEV, 2013 Chevrolet Volt PHEV, and 2013 Prius PHEV) relative to selected gasoline vehicles (2010 Prius HEV and 2014 Mazda 3). Toyota Prius PHV PHEV (blended). Toyota Prius HEV. Yuksel et al.

coal, hydro, natural gas) on well-to-wheel (WTW) energy use and greenhouse gas (GHG) emissions of plug-in hybrid electric vehicles (PHEVs). For the study, they developed well-to-wheel models to investigate energy use and GHG emissions of a PHEV, HEV (hybrid electric vehicle), and conventional internal combustion engine vehicle (ICEV).

Volt for Real?

Plug In Partners

At that point, the internal combustion engine kicks in and recharges the battery while you are driving. But I can’t help thinking that this technology will make the current crop of hybrids like the Toyota Prius and Ford Escape look like Ford Excursions. The Volt is the plug-in hybrid car GM showed at last January’s Detroit Auto Show.

Toyota "Moves"

Plug In Partners

A senior Toyota engineer told the Monitor early last year the company had little interest. On Tuesday, the president of Toyota's North American subsidiary, Jim Press, said the company is looking at developing a plug-in vehicle that can "travel greater distances without using its gas engine."

Time to cut subsidies for fossil fuels? The Green Piece

Green Cars News

Of the fossil fuel subsidies, $70.2billion went to traditional sources such as coal and oil with just $2.3billion dedicated to carbon capture and storage, which is designed to reduce greenhouse gas emissions. By contrast, the hybrid Prius is almost 0.42miles per MJ. Why is so much money dedicated to fossil fuels?

Plug-In Hybrids Are Cleaner (Even on a Coal Grid) [ to top ] This entire section is finally obsolete -- because we now have a definitive study by the Electric Power Research Institute and the Natural Resources Defense Council. People routinely pay more for such options as sunroofs, automatic transmissions, V8 engines and leather seats.
