This is about where I stand. If there's a cheap and easy way to reduce carbon emissions that is already happening because of existing market forces, at the very least we shouldn't stand in its way. I'd even support government subsidies of it, if it helps it kill off coal, but it already seems like it'll do so without any help. Best would be strong climate change policies that set the price of carbon at its actual (high) cost, and that would naturally drive people from coal to gas and gas to low-carbon approaches, but that doesn't seem like it's in the cards in the short term.
