shifting cost back and forth will only help the tax man and who can afford the inflation. Big subsidies for fuel replacement technology is key but who then can compete with oil that only costs 8 bucks to pump from arab oil fields? or cheap "unnatural gas". Speaking of methane, it is so much worse than co2 right? Tax methane please! if co2 is the problem why can we desimate forests that sequester it, and then expect a machine to to the same thing. (sir dick branson's solution). Many answers for such a small problem: electric not the answer is it not a crazy thing to burn fossil fuels to make electricity to replace fossil fuel, me so confused.
