With sensitive and important systems in hospitals requiring an uninterrupted power supply, finding solutions for power outages is becoming increasingly crucial. Iran's favorable potential for renewable energy makes wind and solar energy viable options to support hospital electricity needs and contribute to sustainable development goals. The present work investigates, for the first time, the electricity supply of a part of the Parsian Hospital in Shahrekord using HOMER software. The use of real electricity exchange data with the national grid and the new generation of tree-shaped wind turbines are unique advantages. Results show that an optimal renewable energy-based system consisting of two ۱-kW solar cells and a ۱-kW electric converter costs ۰.۱۱۱ per kWh and solar cells generate ۳% or ۲۹۹۹ kWh/year. The optimal scenario produces ۵۵۱۹۳ kg of CO۲ annually due to national grid electricity use, highlighting the importance of renewable energy adoption in hospitals.
