Study Finds Natural Gas Power Plants Greatly Reduce Pollution From Coal Power Plants
From Scientific American:
Natural gas plants emit a tiny fraction of the smog-causing gases and slightly more than half of the greenhouse gases emitted by their coal-burning counterparts, according to a soon-to-be published study.
The assessment builds upon earlier reports that substituting natural gas for coal has sharply reduced air pollutants from power generation in the United States.
"Since more and more of our electricity is coming from these cleaner power plants, emissions from the power sector are lower by 20, 30, even 40 percent for some gases since 1997," said Joost de Gouw, lead author of the study and an atmospheric scientist with the National Oceanic and Atmospheric Administration's Cooperative Institute for Research in Environmental Sciences at the University of Colorado, Boulder.
