Analysis
In 2025, primary energy from low-carbon energy in Iran stood at 31.77 terawatt-hours.
The figure is down 25.2% on the previous year and up 32.2% over ten years.
Over the whole period, primary energy from low-carbon energy in Iran peaked at 54.56 terawatt-hours in 2019 and was at its lowest, 1.72 terawatt-hours, in 1965.
That places Iran 51st out of 77 countries with data for 2025, putting it in the middle of the range.
The series is highly variable year to year, so single readings are best treated with caution.
