Most of organic farming (biologisch/biologisch-dynamisch) requires little
fertilizer input (fixating nitrogen is expensive, but legumes/rhizobium
bacteria do it at RT and normal pressure, just using sunlight). And you 
get sustainability for free, instead of slowly killing your soil and
contaminating your water table.

Energy is energy, it doesn't matter where it comes from, just how much it
costs. If plastic photovoltaics really lands, oil will become quite cheap --
it will be just used for chemical feedstock, instead of idiotically just
burning it.

Chemistry is quite flexible in regards to feedstock, ranging from fossil
platforming, coal gasification and C1 feedstocks from methane, and of course
biomass.

If you have enough energy you can start from soil carbonate or air carbon
dioxide (but plants fixate it for you, on the cheap).
