The study finds all-electric vehicles cause 86 percent more deaths from air pollution than do cars powered by regular gasoline. Coal produces 39 percent of the country’s electricity, according to the Department of Energy.
But if the power supply comes from natural gas, the all-electric car produces half as many air pollution health problems as gas-powered cars do. And if the power comes from wind, water or wave energy, it produces about one-quarter of the air pollution deaths.
Hybrids and diesel engines are cleaner than gas, causing fewer air pollution deaths and spewing less heat-trapping gas.
But ethanol isn’t, with 80 percent more air pollution mortality, according to the study.
“If we’re using ethanol for environmental benefits, for air quality and climate change, we’re going down the wrong path,” Hill said.
And then there’s the quaint custom of “rolling coal” over Priuses
