As nice as it would be, a not insignificant amount of coal being transported is destined to steel production. Steel is iron + carbon, and the easiest source of carbon is coal. Steel is pretty important, so that's not going away anytime soon. I wonder if carbon capture could make a product that could be used to replace coal here though, and fairly effectively sequester the carbon in an actually useful form?

What biomass grows the fastest without being waterlogged - I imagine bamboo or sugarcane or something

Grow that, and burn it to make carbon neutral steel; bonus points if you do it in a highrise/underground farm but frankly some medium term reversible environmental damage is preferable to killing off way more with climate change

Eh, purity is a thing. Biomass is the opposite of what you want there, but it could be doable. I do wager, however, that the largest "climate cost" of steel comes from the repeated melting of the steel.

There are efforts to develop green steel, it'll be more expensive than coal, but coal is only so cheap because of the huge amount mined for fuel

Many of us have solar power. I could power all my electric usage (including driving an EV) with the solar I can fit on my roof and a modest battery

I'm impressed by recent vertical axis wind turbines, as when we have a week with little sunlight the wind is usually blowing

I live in Seattle, in the winter is why I would have to supplement.
