Coal losing favor as energy source for electric plants

A survey of more than 500 electric utility executives showed a dramatic drop from just a year ago in the number who believe coal has a long-term future. The report estimates that as many as 450 coal-burning power plants could be decommissioned by 2020 as utilities embrace cheap natural gas and deal with aged power plants and the need to curb high pollution levels.

Executives also had generally favorable feelings toward renewables (solar more than wind) as long as costs were competitive.
