If you are saying that 50% of the energy input is from nitrogen, and if the most economical means of supplying nitrogen is from fossil fuel sources, such that the vast majority of it originates from fossil fuels, then wouldn't it be the case that nearly 50% of the energy input of the system is from fossil fuels?
How would this input be "several fold less" than the energy output of the system?
- kragen 5y ago50% of the marketed energy input, that is, which someone bought on the market, is from nitrogen (though I read the same article and I thought it said 90%). But that marketed energy input is only about 20% of the total energy input of the system; the other 80% is the sunlight that falls on the fields.
- legutierr 5y agoA very important distinction! So, maybe fossil-fuel inputs to the system correspond to less than 10% of the total energy output? Would that be accurate?
- Enginerrrd 5y agoYES, that was exactly my point.
