Heating souce pollution

Tom,
Lots of folks have been changing their heating source because of the
oil prices. My question is - which one
pollutes the most/least . . . oil, wood, wood pellets, gas, coal??
Sue

Hi,
Good question! Depends on which pollutant you are talking about. Wood is
probably the most polluting in terms of
particulates. In terms of greenhouse gas pollution, coal and oil are the
worst, with gas close.
The other question is: Who do we want to give our money to?
Tom
