Does burning cause pollution?
Yes, but…. Burning clean, renewable biomass is better than burning coal. The Dell Point stove, for example, is EPA-certified to have emissions no more than 0.5g/h, this is over 10 times lower than EPA limits on emissions. So new generation pellet stoves can have very low emissions. Since any particulate matter from burning biomass is likely to be very alkaline like the ash residue, this small amount of material should not contribute to acid rain problems, it might help alleviate them.
