Pellet stoves for households have become more popular in the past few years as people seek out alternatives to oil and gas heating. Pellets are considered a low-carbon renewable fuel since they come from wood product residue. This is a pellet boiler made in Austria from Okofen.

Oil distributor Sandri has now begun making deliveries of locally-made pellets to some businesses in western Massachusetts.
