“from 485 TWh in 2025 to 950 TWh in 2030”
- Step 01
Take IEA’s figure for 2025: 485 TWh (an estimate).
- Step 02
Convert the unit: terawatt-hours × 1,000,000 = megawatt-hours, which gives 485,000,000 megawatt-hours a year.
- Step 03
Spread it evenly over a year of 31,557,600 seconds (365.25 days): about 15.4 megawatt-hours per second.
- Step 04
Count from 00:00 UTC on 1 January of the current year, so the number resets every New Year.

- Why this can't be exact
- Real activity is not spread evenly: it clusters in working hours, weekdays and seasons, so the count runs ahead or behind the true figure at any given moment. It runs at the 2025 pace until a figure for the current year is published. Digits beyond the first two or three are the model ticking, not extra precision.
