Energy-water-food nexus, the three interdependent primary requirements are essential for life and the need of the hour by the world. The Covid-19 pandemic has proved that countries that are food independent can survive any stressed conditions. For food security, water is essential. Countries that are self-sufficient with water can overcome situations like what the world experienced in the last 2 years. Energy independent countries can be water secured at a cost that will disturb the environment. But when this energy is green and free from carbon footprint, it will promote sustainable development of a country, providing water and food. This technology, which is in its development stage now, will be the future "energy road" to the countries. High radiogenic granites, omnipresent, with low carbon, and low land footprint, can power the millions. In enhanced geothermal systems or engineered geothermal systems (EGS), as the name implies, a reservoir is created in a hot rock, that is devoid of water, and heat from the rock is mined by circulating water or supercritical carbon dioxide (ScCO 2 ) [12]. Three dimensional simulations of EGS systems operated with CO 2 as injection fluid (heat extraction fluid) instead of water was used by Pruess [13] indicate that gravity effects were found to be strong and capable of inducing preferential flow in the bottom of the thermal reservoir. The advantage of ScCO 2 is to avoid water based reservoir that inhibits water rock-interaction, resulting in the precipitation of secondary minerals and clogging the fracture openings. This circulating ScCO 2 is a future promising heat extraction medium with minimum liability on the thermal reservoir.This heat from the granites is utilized for generating electricity, providing heat to support agriculture, space heating, dehydration and finally providing low-cost freshwater from the sea through desalination technology.Unlike hydrothermal resources, that are site-specific, EGS has no such restrictions. Starting with traditional hydrofracturing technology, which was established in Soultz-sous-Forets, France and Cooper basin, Australia [9,11], now EGS is bouncing into a new development of a "closed-loop" system of technology, extracting heat from the granites. This method, unlike the conventional hydrofracturing method, is free from induced seismicity. The closed-loop EGS system is also known as the advanced geothermal systems (AGS) uses a co-axial U-loop in which the working fluid (water or ScCO2) will not enter the rock or flow into the rock fractures [2]. The loop acts as heat exchanger, transferring heat from the rock to the circulating fluid that is collected or flows into a production well. Simulations studies were conducted using varying injection temperatures and varying reservoir temperatures and flow rate [2]. The results show that annual power generation from this system could vary from 2 to 15 GWh with a levelized unit cost of power around US$ 20 to 110 /MWh. Over the years, with technological development this cost could be brought down. ...
