Could have told you that

From United Press International:
Electric cars in China bigger polluters
Electric cars in China are having an impact on pollution more harmful to health than gasoline vehicles, U.S. researchers say.

Researchers at the University of Tennessee, Knoxville, analyzed the emissions and environmental health impacts of five vehicle technologies in 34 major Chinese cities.

While electric cars have been seen as environmentally friendly, the researchers determined they are in fact responsible for more overall harmful particulate matter pollution than gasoline cars, a university release reported Monday.

The reason, they said, is because for electric vehicles, combustion emissions occur where electricity is generated rather than where the vehicle is used, and in China 85 percent of electricity production is from fossil fuels with about 90 percent of that from coal.

"An implicit assumption has been that air quality and health impacts are lower for electric vehicles than for conventional vehicles," civil and environmental engineering professor Chris Cherry said. "Our findings challenge that by comparing what is emitted by vehicle use to what people are actually exposed to."

The researchers say they discovered the power generated in China to operate electric vehicles emits polluting particles at a much higher rate than gasoline vehicles do.
Why is it that the people crying for 'green' technologies don't look one step beyond the first stage of their designs. The unintended consequences are always out there... Posted by DaveH at February 14, 2012 10:00 AM
