How fast is the world building up solar power?
Why it spread
This chart post spread because it covered a hot topic that week and came from an independent author, reaching 160,233 views, 454 likes, 101 reposts, 19 quotes, and 60 saves.
What worked
- The post tackled a hot topic that week, which drove high interest and sharing.
- It came from an independent author, adding credibility and appeal beyond a typical branded account.
- The chart used a line form with medium design polish and medium self labelling, plus a source line, and the source had top quarter reach, all supporting trust and clarity.
What to borrow
We could use the same line chart form and hot topic framing with our own data, making sure to include a clear source line and medium self labelling.
Careful
Do not over read the quote rate being above average or assume the same results without a hot topic and an independent author, and do not copy the exact numbers or field names.
Written by our analysis model from the measured numbers above, not by Our World in Data.
