Air Emissions from Residential Heating: The Wood Heating Option Put into211 Environmental Perspective

摘要

The paper compares the national scale (rather than local) air quality impacts of211u001ethe various residential space heating options. Specifically, it compares the 211u001erelative contributions of the space heating options to fine particlate emissions, 211u001egreenhouse gas emissions, and acid precipitation impacts. The major space heating 211u001eenergy options are natural gas, fuel oil, kerosene, liquiefied petroleum gas 211u001e(LPG), electricity, coal, and wood. Residential wood combustion (RWC) meets 9% of 211u001ethe Nation's space heating energy needs and utilizes a renewable resource. Wood 211u001eis burned regularly in about 30 million homes. Residential wood combution is 211u001eoften perceived as environmentally dirty due to emissions from older wood 211u001eburners.
