Carbon Footprint Reduction and Strategic Benefits of Energy Efficiency: A Case Study in the Healthcare Sector

This study investigates the impact of a solar photovoltaic (SPV) system on electricity consumption and carbon emissions in a private hospital. In 2024, the system produced 7,122,802.80 kWh of renewable electricity, preventing approximately 3,148 metric tons of CO₂e emissions and reducing total electricity costs by 72.3%. Data were analyzed using national tariff coefficients and emission factors published by the Energy Market Regulatory Authority (EPDK) and the Turkish Electricity Transmission Corporation (TEİAŞ). The results show that SPV integration effectively lowers both energy expenditures and carbon intensity in healthcare operations. This case demonstrates the technical feasibility and economic advantage of renewable energy adoption in energy-intensive institutions.
