Ever since the first caveman threw a log on the first fire, burning wood for heating and cooking has helped to define human civilization. But wood as a fuel source has some inherent drawbacks, especially the gases, particulate matter and other pollutants produced by burning logs.
A new generation of high-efficiency wood stoves, however, has become available that are as low in emissions as they are high in energy efficiency. And as the Environmental Protection Agency (EPA) introduces new regulations designed to make wood stoves even more efficient, people are rediscovering wood as a smart, renewable source of energy.
Last week, the EPA proposed tightening its emission standards for wood stoves: Currently, the EPA certifies wood stoves that produce 7.5 grams of fine particulate matter per hour, but new regulations would reduce that level to 4.5 grams per hour by next year, the Fairbanks Daily News-Miner reports, and lower it again to 1.3 grams per hour by 2019.
