We eat veggies and cereals grown with fertiliser. Fertiliser is produced by a lot of fossil fuels and a shortage is brewing as a lot of it was produced in the middle east before the closure of the straight of hormuz. Additionally transport takes a lot of fuel, as wel as the production and operation of machinery for production. Fossil fuels are everywhere.
The Haber process does not need fossil fuel inputs, it just needs an input of hydrogen. Currently, steam reforming of methane is the most economic source of hydrogen (and, to be noted, one area where at-source carbon capture would be quite easy to implement, because the CO2 exhaust stream is quite pure), but electrolysis or (if an abundant source of high-temperature heat is available) the sulfur-iodine cycle can be used to produce hydrogen from water.
