Policymakers look at biomass as attractive for generating electricity because it produces lower greenhouse gas emissions than coal does. But a new study suggests this isn’t the best use of biomass, an energy source made from plant matter. Researchers report that burning biomass instead of fuel oil to heat homes is a far cheaper way to cut greenhouse gas emissions (Environ. Sci. Technol., DOI: 10.1021/es202752b).
