Has anyone broken down the difference in energy between artificially creating growing conditions in the middle of cities compared to just transporting the food from where it grows easily? Trains and ships which transport most food are incredibly energy efficient per ton transported

Trains can transport one ton of goods 470 miles on one gallon of fuel and ships can transport one ton of goods 600 miles on one gallon of fuel. If a urban farm can produce one ton of food it needs to consume less than a few gallons of fuel's worth of energy in lighting and other city-specific infrastructure in order to come out ahead of growing food where it grows best
