Interesting article on how wood is making a comeback thanks to pellet technology. The US and Europe relied on wood for heating only a century ago. These energy-dense pellets can be used to generate heat or electricity, or both at the same time. The pellets resemble dry dog kibble and are mostly made form mill residue like sawdust and wood shavings. The demand is especially strong in Europe, where high prices for heating oil and clean energy requirements have expanded interests in alternatives. However over the long term, interest in Asia and North America could grow rapidly as well.
