Energy Wastage Assessment and Optimization
Identifying energy wastage through energy reviews is a crucial step in advancing the achievement of Sustainable Development Goal (SDG) 7: Affordable and Clean Energy. In 2024, Universitas Sebelas Maret (UNS) conducted comprehensive energy reviews to identify areas with the highest levels of energy wastage as part of its ongoing commitment to strengthen its role as a sustainable and environmentally responsible university. Through these assessments, UNS identified inefficiencies in several campus facilities, with the findings guiding the university in implementing targeted measures, including the gradual replacement of conventional devices with energy-efficient alternatives, the expansion of renewable energy installations, and the adoption of smarter energy management practices.
