For example either renewables + batteries or nuclear could have displaced coal. Just because there wasn't enough money/political support for it doesn't mean that we shouldn't worry about both fracking and coal usage consequences.
And no, renewables + batteries and nuclear couldn't have displaced coal precisely due to a lack of money and political support. Why are those constraints any less important? The goal isn't just to build renewable tech, the goal is to build a functional society that uses renewable tech. There also is a technological constraint here, fracking became viable in the early 2000s before modern battery and solar tech existed at its current price point.
we don't use domestic oil, we sell it overseas
and oil until pop-up "ai" datacenters was not used for power production
you are thinking about solar and wind power for coal's demise
which now they are also defunding, even worse reusing the funds for coal investment
You... really need to read more before forming your opinions
Solar and wind are commercially viable and provide about 30% of the electrical energy in Texas. Around 50% of California's daytime electrical energy is provided by solar and wind power. New projects are typically hamstrung by transmission permitting constraints.
While subsidies would help substantially, they aren't a necessary condition for continued adoption of renewable energy sources. Storage is probably the next big hurdle to displace fossil fuels once there's sufficient progress with transmission.
