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.

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

Patterned portions represent GHG emissions associated with electric propulsion. Solid left bar = hydro electricity scenario.) 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.,

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.

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.

U Chicago, MIT study suggests ongoing use of fossil fuels absent new carbon taxes

Green Car Congress

A paper by a team from the University of Chicago and MIT suggests that technology-driven cost reductions in fossil fuels will lead to the continued use of fossil fuels—oil, gas, and coal—unless governments pass new taxes on carbon emissions. for oil, 24% for coal, and 20% for natural gas.

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.

Plug-In Hybrids (or Plugin Hybrids)

Tony Karrer Delicious EVdriven

You can fill it up at the gas station, and you can plug it in to any 120-volt outlet. But when you do, your car essentially becomes an electric vehicle with a gas-tank backup. So youll have a cleaner, cheaper, quieter car for your local travel, and the gas tank is always there should you need to drive longer distances.
