Yes, coal is a bad polluter, but natural gas is not. And all costs and benefits of each alternative must be considered. On balance, natural gas is currently a better option than renewables.

Now your beginning to think like an economist (a compliment in my circles, believe if or not) A great way to make it easy for people to take into account the costs and benefits of alternatives (including externalities) is with Pigouvian taxes:https://taxfoundation.org/tax-basics/pigouvian-tax/ …

Ha. I've been thinking like an economist all along, and if you discount the anti-CO2 hysteria, you'll come to the same conclusions I have. The problem is the hysterics that don't know Econ 101, and the economists that don't speak up against their antics.

So you think we should have a larger Pigouvian tax on coal and oil to accelerate the switch to cleaner sources like most economists do? I was literally at a conference of economists this morning where this was discussed. Here's a good list:https://en.wikipedia.org/wiki/Pigou_Club

Here's another example of what economists think about carbon taxes: https://www.igmchicago.org/surveys/carbon-taxes-ii/ … I hope you are in step with the overwhelming majority of economists, but it doesn't sound like you are.

The optimal carbon tax is a function of the size of the externality, which is being massively overestimated. The economists are being led astray by bad climate models. Got it?

I really liked your book and many of your insights about AI, but when it comes to the costs of climate change, I put more weight on the estimates of people who have studied this question carefully, like the IPCC and Bill Nordhaus. https://report.ipcc.ch/sr15/pdf/sr15_chapter2.pdf …

And FWIW, the externality from burning coal is overwhelmingly bad even before including any cost at all from climate change. Particulate pollution is deadly.

It would be well worth if we had no better choices, but we do (natural gas, for one). Or would you rather go back to pre-industrial times?

You and I agree then, with Nordhaus et al, that (since we do have better choices) we'd be better off without coal electric generation. A Pigouvian tax would help us get to a better outcome where this category of energy production were replaced.

But you don't seem to agree with me or the market that natural gas is better than renewables.

I’d I agree with the market if it included all relevant externalities. I think that is your position too. I think we have different views on the externalities. And while I agree that experts can be wrong, I would double check my analysis if they overwhelmingly disagreed with me

I have, and they don't (that's the impression you get if you read the media instead of talk to the actual experts; again, reading "Unsettled" should be a real eye-opener).
