I was Menard's and noticed 40 lb bags of wood pellets selling for $3.99 each! Because any dry wood per lb has the same BTU content I do believe, then it would appear that each 40 lbs of firewood I collect is worth $3.99 retail. That means I have many THOUSANDS of dollars worth of firewood already cut, splt, and stacked with an endless supply of solar-powered automatically growing trees for future fuel purposes that will NEVER run out! This firewood energy resource is like having a self-renewing private gold mine or oil well on my own property with the added beauty that if managed right, I can actually improve the forest environment and wildlife habitat by harvesting firewood with none of the environmental harm of having a gold mine or oil well would have. Not bad! But a small gold mine would be a nice addition.
