In 2021, ISA consumed a total of 218,728.8 Gigajoules of energy across its operations. Of this total, 63.71% 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 36.29% 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 2021, ISA consumed a total of 218,728.8 Gigajoules of energy, of which 63.71% was derived from renewable sources, including biofuels, biomass, biogas, solar, and wind power.a
This moderate level of renewable energy adoption indicates that ISA is transitioning toward cleaner energy sources, though a significant share of its energy mix still relies on non-renewable inputs.
Since 2019, ISA's total energy consumption increased by 3.23%, including a 2.05% increase in 2021, reflecting a sustained rise in overall energy demand.a
Over the same period, the share of renewable energy decreased by 9.27%, with a further 2.98% drop in 2021, highlighting a weakening in renewable energy performance.a
Overall, ISA is consuming more energy while simultaneously reducing its use of renewable sources, raising concerns about a growing dependency on fossil fuels and the company’s alignment with sustainability goals.
