Let me provide example of what I think is sustainable. This system uses electrical energy from grid(still much less energy than fossil eqivalent used by mainstream farming machinery) and occassional local as-needed application of pesticides. I know the man who developed it, he was able to repay all loans without subsidies and he is able to provide food for 50 people iirc. http://www.slideshare.net/inmediaslovakia/farmlandia http://www.slideshare.net/inmediaslovakia/farmlandia
