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.

How to Hasten India’s Transition Away From Coal

Cars That Think

The country’s electricity consumption in 2019 was nearly six times as great as in 1990. costs less than fossil-fuel-based electricity. While electricity from older coal plants in India costs 2.7 In 2021, about 73 percent of the country’s electricity was produced from coal, and only 9.6 IIT Madras.

Researchers find Nissan LEAF creates less CO2 than Toyota Prius hybrid in west US and Texas, but more in N. Midwest

Green Car Congress

Regionally specific lifecycle CO 2 emissions per mile traveled for plug-in hybrid electric vehicles (PHEVs) and battery electric vehicles (BEVs) in the US can vary widely based on grid emission factors (i.e., Under some conditions, the battery electric Nissan LEAF can produce higher emissions than a Toyota Prius hybrid.

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

Green Car Congress

A US-wide county-level study comparing lifecycle greenhouse gas (GHG) emissions from several light-duty passenger gasoline and plug-in electric vehicles (PEVs) has found that PEVs can have larger or smaller carbon footprints than gasoline vehicles depending on regional factors and the specific vehicle models being compared.

Solid portions represent GHG emissions associated with gasoline propulsion. Patterned portions represent GHG emissions associated with electric propulsion. Solid left bar = hydro electricity scenario.) First, driving distance determines the proportions of electricity and gasoline consumed by the PHEV.

Volt for Real?

Plug In Partners

F or those who think that GM is not serious about its new PHEV , the Volt , here is a piece that makes you think they are: The Volt To Be Lutz's Legacy May 21, 2007 So, I heard General Motors’ Bob Lutz on National Public Radio’s “Wait. The Volt is the plug-in hybrid car GM showed at last January’s Detroit Auto Show.

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. The question of electricity costs vs. health and environmental cost is important to ask everywhere, Michalek said. Credit: ACS, Weis et al.
