Natural Gas Power Plants Emit Up To 120 Times More Methane Than Previously Estimated
By Steve Horn for Desmog Blog - Researchers at Purdue University and the Environmental Defense Fund have concluded in a recent study that natural gas power plants release 21–120 times more methane than earlier estimates. Published in the journal Environmental Science and Technology, the study also found that for oil refineries, emission rates were 11–90 times more than initial estimates. Natural gas, long touted as a cleaner and more climate-friendly alternative to burning coal, is obtained in the U.S. mostly via the controversial horizontal drilling method known as hydraulic fracturing (“fracking”).
