Well, if energy were cheap enough you could just dig huge, multi-level tunnels, fill them full of grow lights, and raise all the grass-fed beef you wanted.

It's the same with water -- there's plenty of water in the ocean. If energy were cheap enough, you could just distill seawater and get all the freshwater you wanted.

"Limitless" energy would mean the ability to grow crops and meat and everything with very little worry about efficiency.
