About 29–30% of the sunlight that reaches Earth is reflected back to space, and about 70–71% is absorbed by the atmosphere, land, and oceans.

Mini breakdown

  • Incoming solar energy: treated as 100%.
  • Reflected (Earth’s average albedo): about 29–30% goes back to space from clouds, atmospheric particles, ice, oceans, and land surfaces.
  • Absorbed: the remaining ~70–71% is taken up by the atmosphere and surface, heating the planet and driving weather, climate, and biological processes like photosynthesis.

These numbers are global long‑term averages; they can shift slightly with things like cloud cover, ice melt, seasonal changes, and human‑driven changes to land use and air pollution.

TL;DR: Roughly 30% of sunlight is reflected, roughly 70% is absorbed. ✅
