Semarang \u2014 Universitas Negeri Semarang (UNNES) recorded total energy consumption of 37,194 gigajoules (GJ) in 2025<\/strong>, covering grid electricity, on-campus solar energy, fuel for official vehicles, and fuel for backup generators. This consolidated inventory provides a baseline for assessing energy use across university operations and identifying opportunities to improve efficiency.<\/p>\n\n\n\n

The university\u2019s total energy use includes both electricity consumption and direct fuel consumption<\/strong>. Electricity supplied by the national grid (PLN) accounted for 32,016.996 GJ<\/strong>, equivalent to 8,893,610 kWh<\/strong>. On-campus solar photovoltaic systems across 20 monitored locations contributed a further 2,538.8496 GJ<\/strong>, equivalent to 705,236 kWh<\/strong>.<\/p>\n\n\n\n

Beyond electricity, UNNES recorded an estimated 1,976.36 GJ<\/strong> from Pertamax fuel used by official university vehicles and 661.88 GJ<\/strong> from Pertamina Dex fuel used for backup generators. Together, these four categories amounted to 37,194.0856 GJ<\/strong>, reported as 37,194 GJ<\/strong> after rounding.<\/p>\n\n\n\n

The inventory draws on electricity records maintained through the myUNNES-Office system<\/strong> and annual fuel purchase records. Electricity consumption is converted into gigajoules using a conversion factor of 0.0036 GJ per kWh<\/strong>, allowing electricity and fuel use to be consolidated into a common reporting unit. Generator fuel is included in the total, while the electricity produced from that fuel is not added separately, avoiding double counting.<\/p>\n\n\n

By documenting its total annual energy consumption, UNNES establishes a measurable foundation for energy management. These records support targeted efficiency measures, planning for renewable energy infrastructure, and monitoring progress toward lower-carbon campus operations, reflecting the university\u2019s commitment to responsible energy use and climate action.<\/p>\n\n\n\n
