Earlier quoted context omitted.
The fact that the term "clean coal" can be bandied about with a straight face says something about the state of science education of the general public. (Pretty much the same knowledge needed to instantly realize that various wind/solar operated water-from-air devices and Solar Freakin Roadways aren't viable from back of the envelope calcs.)
Coal mining and related production is a large employer. It's about propping up small coal-towns.
The average coal miner salary is ~$22/hr, or ~$42k/year. 174,000 coal workers in the US @ $31,668k/year (the max SS benefit permitted) = $5.5 billion/year. This is not expensive, nor in perpetuity, only the years from now until they would've hit their full retirement age regardless, not to mention the cost savings from drug addiction and other social negatives currently occurring from the industry collapsing (please, please, please take the 2 minutes to read this footnote) [1].
People should not be harmed by our transition to renewables, and it is laughable that we can't afford to take care of those no longer employed within the economy.
This is not unprecedented. The shipping industry used redundancy payments to transition longshoremen out of the workforce when containerization exploded, funded by profits from the efficiency gains of containerization. I'm simply arguing for the formalization of the process, and administration through the Social Security Administration (one of the most efficient orgs in the US government).
To be clear: I am essentially advocating a bridge basic income for these workers. Not subsidies, not incentives. You quit your job at the coal mine or coal generator today, and you're retired from the coal industry.
EDIT: @derekdahmer & @ArkyBeagle: I'm not requiring someone to retire if they don't want to. I'm simply ensuring they don't fall into poverty. What more can be done when your job is destroying the environment? Allow it to continue? That is unacceptable. I'm not proposing welfare, I'm proposing financial freedom to explore other options to find purpose and self actualize.
