Table 2 Interactions among energy and food on the demand side with nexus approach.

From: Framing a novel holistic energy subsystem structure for water-energy-food nexus based on existing literature (basic concepts)

 

Energy

Interaction relationship

Food

Interaction relationship

Energy

  

Required energy for agricultural machinery

(1) \(ME=E\times \frac{G}{T}\times {Q}_{h}\)

Required energy for agricultural inputs production

(2) Energy intensity data

Required energy for labor

(3 )\({E}_{l}={W}_{l}\times {E}_{i}\)

Food

Required biomass per unit of energy generation

Biomass intensity data

  
  1. ME, machinery energy; E, production energy of the machine; G, weight of the machine; T, economic life of the machine; Qh, total working hours of the machine in a season; El, human labor energy; Wl, number of workers per hectare; Ei, energy use per worker.
