But where I live, it would be difficult. Yes, there is a "CO2 tax" here. Twenty years ago I converted my wood-burning fireplace to natural gas. That was being, in my opinion, environmentally friendly (I prefer burning wood -- more pleasant). If the cost of NG goes too high I can revert to wood. Electricity is out, because the local power company prices it at around 7 times higher than natural gas. $800 per month to heat my house. $125 for natural gas. Wood? 3 to 6 cords should do... At 1 cord per acre, I would need 3 to 6 acres. I could buy 40 acres, put up a house, and produce my own biofuel as well. No "price on carbon emissions". If you can convince me that CO2 is an existential threat, that is one thing. I can move to Memphis where I don't need to heat my home. You cannot deny me the right to do that, if you think that CO2 is that threat. Otherwise, you can tax me until I refuse to participate.
