There are hard limits for how much energy we can provide to computation, but we are not even close to what we can do in a non-suicidal way. In addition to expanding renewables, we could also expand nuclear and start building Thorium reactors - this alone ensures at least an extra order of magnitude in capacity compared to Uranium.
As for the compute side, we are running inference on GPUs which are designed for training. There are enormous inefficiencies in data movement in these platforms.
If we play our cards right we might have autonomous robots mining lunar resources and building more autonomous robots so they can mine even more. If we manage to bootstrap a space industry on the Moon with primarily autonomous operations and full ISRU, we are on our way to build space datacenters that might actually be economically viable.
There is a lot of stuff that needs to happen before we have a Dyson ring or a Matrioska brain around the Sun, but we don’t need to break any laws of physics for that.

I'm honestly not sure how anyone can be remotely aware of the other major consequence of our energy consumption, climate change, and make this statement.
We're far more likely to be extinct in 100 years than see any of your sci-fi proposals come to fruition.
But I guess that gets to the point of all of this discussion: belief in a technological singularity is just a different flavor of the religious tools we have used to avert existential dread for thousands of years. You need to believe these things are true so there's nothing that can ever be said to convince you otherwise.
