At this </span> <span style="font-size:12px;">point, underground thermal energy storage has been suggested as a clean and efficient alternative of energy extraction for </span> <span style="font-size:12px;">the sustainable future as one of the renewable energy varieties. Thermal energy storage systems in the aquifers have  </span> <span style="font-size:12px;">preluded the energy market with great success in many countries. Hot and cold natural energy sources are stored in the </span> <span style="font-size:12px;">aquifer by using underground water to store the heat in this system. Efficiency of the system depends on several factors </span> <span style="font-size:12px;">including groundwater temperatures and flow characteristics. Among the different underground thermal energy storage  </span> <span style="font-size:12px;">options, one of the most promising and commercial option is known as aquifer thermal energy storage (ATES). Based on </span> <span style="font-size:12px;">the recent developments reported in the literature, general design procedures and construction techniques as well as </span> <span style="font-size:12px;">relationships related with the efficiency of ATES systems are reviewed within the scope of this paper. The applications  </span> <span style="font-size:12px;">from the world and Turkey were discussed in a comparative approach. </span> </div>}, number={2}, publisher={Murat YAKAR}
