24 April 2008 - 11:55Keep the Home Fires Burning?
Joanne and Louise left comments on my Earth Day post, and asked about the environmental impacts of wood-burning as a heating source for rural communities (in Alberta and BC).
Like most questions, there isn’t a clear cut answer (pun intended)! Every fuel source has a significant list of emissions. To its credit, wood is a renewable resource that we’ve been using to cook our food and heat our dwellings since, well, we discovered fire.
The benefits of wood burning is that there is no ‘extraction’ process (like with fossil fuels such as natural gas or oil), you can use how much you need, and you can invest in wood that was harvested sustainably.
Unfortunately, burning wood also has more than its share of health hazards and negative environmental impacts. Fireplaces and wood stoves can emit substantial quantities of pollutants to indoor and outdoor air especially if an inefficient system is used. You have to consider the harmful contaminants in wood smoke, the health effects of wood smoke and the significance of wood smoke emissions.
If you are limited by your surroundings and local options and decide to use wood-burning appliances, high-efficiency wood-burning ones are best. Check to see if the one you have is an advanced combustion system, which can burn up to a third less wood while generating the same amount of heat.
