In all fairness, I did listen to a radio program discussing the shortage of sawdust (used to make wood pellets) linked to the slowdown in construction. However, it was mainly in the states where such large-scale construction did occur, which produced lots and lots of sawdust, thus keeping the prices low.
The usuals, whatever I post is my opinion, yaddayaddayadda. I'm still learning this, so if you listen to me, well, good luck to you :)
