Greece energy transition
Our World in Data's line chart drew 46.2K views on X: 0.8x its typical post and #50 of 139 Our World in Data charts we track by views. Read Oct 10, 2026.
In 2014, half of Greece's electricity was generated by coal.
Why it spread
This post spread because it paired a self explaining line chart about Greece turning from coal to solar and wind with a hot topic that week, and it reached 46,162 views, 718 likes, 163 reposts, 16 quotes, and 65 saves.
What worked
- The post text explains itself in two short sentences, moving from half of Greece's electricity coming from coal in 2014 to just 6% a decade later.
- The chart is a line chart with high self labelling and a source line, so readers could understand the trend without extra explanation.
- It was branded and tied to a hot topic that week, which helped a data journalism account with top quarter source reach earn 163 reposts and 718 likes.
What to borrow
We could use the same form by taking one clear before and after shift in our own data, stating it in two plain sentences, and pairing it with a highly self labelled line chart and a visible source line.
Careful
Do not over read the quote rate, which was below average, and do not assume the same framing will spread just because the topic is hot or the account is branded.
