BOSTON (AP) -- A new study has found that wood-burning power plants using trees and other "biomass" from New England forests releases more greenhouse gases into the atmosphere than coal over time.
The six-month study was commissioned by Massachusetts state environmental officials.
The Manomet Center for Conservation Sciences conducted the report and concluded that the net cumulative emissions of greenhouse gases from replacing coal-fired plants with biomass would be 3 percent greater by 2050 than from using coal to generate electricity.
The study has broad policy implications for states like Massachusetts, and environmental groups called it "a wake up call."
