In 2024, KT consumed a total of 23.57 million Gigajoules of energy across its operations. Of this total, 2.03% was sourced from renewable energy, either derived from natural resources like biofuels, biomass, or biogas, or generated using renewable technologies such as solar or wind power. The remaining 97.97% was classified as non-renewable energy, coming from fossil-based fuels such as coal, natural gas, or crude oil, or from non-renewable generation technologies like nuclear power.a
In 2024, KT consumed a total of 23.57 million Gigajoules of energy, of which 2.03% was derived from renewable sources, including biofuels, biomass, biogas, solar, and wind power.a
This low level of renewable energy use highlights a heavy reliance on fossil fuels or other non-renewable sources, suggesting that KT has considerable room to improve its energy sustainability strategy.
Since 2022, KT's total energy consumption increased by 2.74%, including a 1.01% increase in 2024, reflecting a sustained rise in overall energy demand.a
Over the same period, the share of renewable energy in KT's consumption increased by 6,560.57%, including a 87.44% increase in 2024, showing consistent progress in clean energy adoption.a
Overall, KT has seen rising energy demand, but has also made strong and consistent progress in increasing its reliance on renewable energy—mitigating the environmental impact of its growing consumption.
