If we’re going to tax (supposedly) negative externalities such as carbon, “clean energy” can’t get off free. We are offshoring pollution — think neodymium for wind turbines mined in Mongolia, solar cells in China, etc. And don’t forget, manufacturing these clean energy components produces carbon, which would get off scot-free overseas.
A better idea is to eliminate all energy subsidies and let economics do it’s job. Case in point, natural gas which is reducing our carbon intensity on a large scale with clean, reliable, and dispatchable power.
