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. Jeremy Michalek.

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. Small Battery: For this scenario, they modified the base case so that the vehicle fleet is based on the Toyota Plug-in Prius.

Coal Into Cars: The Good, the Bad, the Ugly

Plugs and Cars

The Ugly Coal sucks, there's really no two ways about it. But not all use of coal is alike. The Good About half our electricity comes from coal, and that will change, at best, slowly as we move to renewables. That includes the worst, most coal dependent areas. Support knows no party.

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

coal, hydro, natural gas) on well-to-wheel (WTW) energy use and greenhouse gas (GHG) emissions of plug-in hybrid electric vehicles (PHEVs). 100% coal (pulverized coal boiler). Regardless of the driving pattern, total energy use of the PHEV is lowest for the hydroelectric scenario and highest for the coal scenario.

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. In some areas where wind and hydropower is wasted at night, the rate can be as low as 2-3 cents per kWh.

The Budget 2009 - working towards sustainable transport

Green Cars News

Models anticipated for 2011 include a plug-in Toyota Prius and Vauxhall Ampera. Additional support was announced in this area, including £525 million to support offshore wind power generation and £60 million to fund carbon capture and storage technologies which could be fitted to future and existing coal fired power stations.
