Unless we start building tons of fission plants or "solve" fusion power, 95% of our staple crops will be more efficient to grow directly with the sun. So maybe indoor in a greenhouse sense, but not an artificially lit warehouse.
The only plants that need less sun are shade tolerant herbs and leafy greens which are already a very tiny portion of our agricultural land usage.
