But Biomass is a good idea?????
The wood-burning fireplace warming the den is cozy, but it can belch as much pollution as an old diesel bus. That vintage wood stove cranks out heat, but it can contribute to asthma attacks in the neighborhood, or even inside the house. When fuel oil prices soar, as they have this year, more Mainers turn to wood heat. But wood smoke contains fine particles that can cause health problems. In some locations, especially river valleys, residential wood smoke is a major source of winter air pollution.Now the U.S. Environmental Protection Agency is preparing regulations meant to tighten emissions limits for new residential wood heaters. For the first time, these regulations will cover pellet stoves and outdoor boilers — heat sources that have become popular in Maine.
