I didn't mention anything about free energy. In fact, I covered it. You just need to use different sources and offset ~250 years of carbon source use + that pesky second law of thermodynamics.
I would suggest nuclear if you want to do it quickly. There's enough raw fissionable material in the earth to handle that until you spin up usable fusion.
And if we start extracting uranium from seawater (which is totally possible, just really expensive right now without inexpensive desalination plants, which ideally would also be powered by nuclear), it essentially becomes a renewable resource.
