RE the intersection of energy generation and tax incentives: one of the biggest beneficiaries of "clean coal" tax incentives is the Arthur J. Gallagher corporation, which most people know (if they know them at all) as an insurance broker. Gallagher makes beaucoup $ w/ clean coal.
In 2019, Gallagher reported $388 million of US pretax income, on which it reported $3.8M of current federal income tax. A cool 1% federal tax rate, which is actually an uptick from the precisely 0% rate the company reported on a similar amount of income the year before.
