The sole reason for more EPA government regulations is to CONTROL fuel sources. Nothing to do with pollution, thats just the excuse, its everything to do with control of your lives and making you dependent on a fuel source that the government already has control of , or is profiting off of thru taxes. Your wood makes you free in more ways than 1. I implore all of those whom choose to seek their own choice of fuel by any means they see fit. They did the same thing to home brew biodiesel by raising the cost of the chemicals required to make it, by hundreds of %. Since the govt. never asks you for permission to regulate or tax the heck out of your basic needs, I think the least you can do is return the favor. What they don't know can't hurt you. Grandfather them all in. Carbon foot print may arce. OWB's are more green than any of these other tax credit petrolium fuel source appliances pushed by carbon credit,green energy disguises. You plant it-cut it-burn it- it re-grows, recycling your way the true green way ( the way its been done for centuries), not what some yuppie claims is now green because some paid off politician said it was.
