Lubershane: Solar PV and motors require 50x less land than animal power
“But the total efficiency, if you take solar PV and then run that electricity through an electric motor to do useful work, It's on the order of probably 15 to 20%. So the upshot here is we need like 50 times less land today to get the same amount of energy, use…”

Webber: Global photosynthesis averages 0.3% efficiency, peaking at 10%
“The global photosynthetic mean is like.3% efficient, and really good crops in really healthy areas, and the ecosystem might be as high as a few percent, maybe eight or 10% in some places, and this is far shy of the efficiency of like an electric motor.”
