The economic impact is debatable over a long time period as the dislocation of people and hardening of waterfront cities . I have little problem with carbon tax of several $100B a year in the US. The proceeds of which would go to tax credits for energy efficiency. But that assumes Government would be efficient or rational. So my more realistic hope follows.
I *hope* Tesla and technology forces a massive shift to electric cars/trucks/self driving vehicles. And battery technology in cars allows for many vehicles to store energy for peak demand periods. I saw an article where in Europe some electric company was paying up to like $1800 a year for people who charged their cars during non-peak and then discharged back to the grid during peak. If I were starting off again I would work on thermo-electric conversion of geothermal heat to electricity. In my opinion, we desperately need to break the carbon cycle for global warming as well as get away from use of coal for what it puts into the atmosphere.
I think there would be little change for the better decades as the CO2 we have put into the atmosphere isn't going away fast. Again,
