Technology

It's near limitless in the sense that the fuel for it will not run out. ... But to be honest, the 'unlimited energy' thing is mostly marketing hype. If we were worried about fuel running out, then solar would be the obvious go-to. That's even less likely to run out than fusion power, and it has the advantage that we can already build it. And fusion, like solar and everything else, still requires land and resources to build the power plants. There are hopes that fusion power plants might be be more space efficient or something, but that obviously isn't the case currently. Currently the situation is that people have been working on this for generations and the big breakthrough is that we can now momentarily break-even with power on a small scale with state of the art equipment. So I think it's a bit too soon to claim it will have any advantages over solar. Right now it is not viable at all, and any future advantages are just speculation.

That said, fusion power is technology worth pursuing. It's not complete garbage green-washing (unlike "carbon capture and storage", which really is complete garbage), but the idea that fusion it's some holy-grail of unlimited power is ... well ... basically just good marketing to keep the research funds flowing.
