Productivity by automation is constrained by the available energy, also economic growth could already be limited by the lack of availale energy.

Solar panels are pretty cheap. If lack of energy were a problem, I'd expect a lot more of them.

They are cheap, but production of them is currently growing roughly exponentially, so I don’t think your argument holds.

The cost of energy is going towards zero while (and because) available energy is going to infinity.
