And we are not even close to the energy efficiency of photosynthesis.

Citation? Wikipedia gives Photosynthetic efficiency at under 11% and Solar cell efficiency up to 40% for research-grade photocells and one company claims 24% efficiency for their commercial cells.

Certainly we're not close to the energy/cost efficiency of photosynthesis.
