Fusion of atomic nuclei can't yet be done by humans at better than unity. Is fusion not a power source just because we can't do it yet? If so, the sun has news for you.

I’m talking about usable energy by humans today. This is by far the most critical thing to our society and the climate crisis.

Steam generated by burning coal is in no way a clean energy source while steam generated by geo thermals is. It’s just boiled water either way. Take some time to consider why that difference is relevant.
