France nuclear power generation
Our World in Data's line chart drew 98.4K views on X: 3.4x its typical post and #23 of 139 Our World in Data charts we track by views. Read Oct 10, 2026.
France opened a flurry of nuclear power plants in the 1980s and 1990s, giving it low-carbon electricity ever since, At the turn of the millennium, France had one of the lowest-carbon electricity grids in Europe (and the world).
Why it spread
This post spread because it explained itself clearly and landed on a hot topic that week, reaching 98,449 views with 452 likes, 105 reposts, 18 quotes, and 63 saves.
What worked
- The chart is a simple line that shows France's nuclear power growing rapidly then plateauing after 1990, so the trend reads at a glance.
- The post text explains itself by tying the 1980s and 1990s plant openings to low-carbon electricity ever since, and it contrasts France with the UK and Germany emitting well over 500 grams.
- It is branded, carries a source line, and uses high self-labelling, which builds trust and makes the chart easy to share.
What to borrow
We could pair one of our own line charts with a short self-explaining caption that names the cause and the contrast, and keep a visible source line and brand mark.
Careful
Do not over-read the spread as proof the design alone did it, since the topic was hot that week and the account is a large data-journalism brand with top-quarter source reach.
