The Sun.
Sunlight supplies the vast majority of the energy that drives Earth’s climate, weather, photosynthesis, and most ecosystems. By comparison, heat from Earth’s interior (the “hot core”) is tiny — global geothermal heat flow is on the order of ~47 TW vs. incoming solar power of ~1.74×10^17 W (≈174,000 TW), so solar input is >99.97% of the total.
