Pollution controls are usually minimal: “…small-scale biomass burners, like those being installed to provide heat to schools around the country, typically only have minimal controls.
We would need to use a wood burner with very advances pollution controls
When asked about potential solutions for heating buildings other than biomass, Ewall said that the college should start by weatherizing buildings — weather-stripping windows and implementing room-to-room temperature controls to avoid overheated students opening their windows and wasting energy.
Yes, energy efficiency is important, but there will always be heating needs, and Ewall isn't getting to the point.
