In 2026, Rinnai consumed a total of 1.09 million Gigajoules of energy across its operations. Of this total, 3.93% 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 96.07% 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 2026, Rinnai consumed a total of 1.09 million Gigajoules of energy, of which 3.93% 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 Rinnai has considerable room to improve its energy sustainability strategy.
Since 2022, Rinnai's total energy consumption decreased by 4.22%, yet rose by 2.17% in 2026, pointing to a potential reversal in recent energy-saving progress.a
Over the same period, the share of renewable energy in Rinnai's consumption increased by 8,301.17%, including a 173.53% increase in 2026, showing consistent progress in clean energy adoption.a
Overall, Rinnai’s energy trends reveal a complex picture, with variations in total consumption and renewable sourcing. A closer examination of operational drivers and sourcing strategies is needed to fully assess the company’s environmental impact.
