Are you really bringing up resource limitation when your point is energy sources that depend on finite fuel?

Besides, the current form of renewables is the best option we have right now, so we should put all efforts into that. Once we find something better, absolutely go for that.

Correct, but don’t forget that renewables is an umbrella term.

If you use solar, wind, hydropower, geothermal and bioenenergy, you’re diversified and it’s all renewable. Add in storage and there’s not much of an issue anymore.
