> The absolute best way to fix the problem is to develop new technologies which are cleaner and cheaper and equivalent or better than what they are replacing. Yes and no. We absolutely have to pursue cleaner technologies but many of those technologies are not mature yet. We shouldn't continue driving full throttle towards the cliff when we don't actually have fully developed solutions to go carbon neutral yet. It would be absolutely irrational not to cut consumption. > It is absolutely possible to discourage “dirty” production by taxing the externalities to drive production to cleaner methods at a higher cost. The effect of this is to drive up costs and this causes inefficiency, which is an economists way of saying it is harmful (to the economy and therefore to people). Yes, and this is part of what has helped renewable energy develop. If fossil fuel energy sources don't have their negative externalities priced in, they're going to be more economically attractive than renewable energy than they should be. When the true price is factored in, renewables are far better. In absence of a carbon tax, subsidies are another way to make the develop of renewables more favorable. > Similarly with EVs you have a product which now that’s it’s gotten to a point where you can make one that is better in every way than an ICE vehicle, manufacturers are racing to switch. You can’t tax your way to an EV future, but you can subsidize the R&D which ultimately allows a superior product to come to market. Part of the reason EV's have gotten to that point is because of tax subsidies and government investment. Without those helping hands EV's wouldn't be as far along as they are. > The alternative — that we need to sap trillions of dollars out of the economy to deploy substandard products and infrastructure which will deliver the same or worse service at higher cost, ban scores of products which people use, enjoy, or rely on, and increase taxes on a massive scale, I think that’s not only a losing proposition but that’s where you end up with the disastrous politics we have today. People need to let go of this idea that somehow we can make a shift to 100% renewables without any sacrifice. In some places the shift will be painless, in others it won't be. But make no mistake, the pain of climate catastrophe is going to make the pain of going carbon neutral look like a paper cut.
