Everything we are capable of now is the direct result of vast energy availability from fossil fuel. It is so energy dense, transportable, storable, and cheap, it is nearly indistinguishable from magic. 1 gallon of gas or diesel has 35kWh of thermal energy. For 5 bucks.

570 Liters of diesel per day = 5,700 kWh per day. Even if you cut that by2.5 for the extra efficiency of electric motors with round trip losses you get 2,300 kWh per day for a large size farm machine. 12 Tesla grid scale 200kWh powerpacks per day to hot swap in and out. for just one tractor. We are going to need to start making a lot of wire to get all of this power around.
