If a pellet shortage does develop, and it well may, it won't be from overuse, but rather the US 32% tax on wood products from Canada. The lumber mills create the raw material for the pellet mills (sawdust), and production has been cut way back A large percentage of wood pellets sold in the northern US are from Canada.
I have an acquaintance who sells pellets in New England, and he is now ordering them by the traincar load from west of the Rockies. Even with that, he says pellets this year will cost about 50% more than they did ten years ago, and that's not too shabby when you look at gas and oil prices compared to just a few years ago.
