Episode notes
Sunlight Is The Ultimate Energy Source
- Jesse Peltan argues that all usable energy flows on Earth ultimately come from the sun and sunlight dwarfs every other source.
- He shows quantitatively that sunlight's abundance and limits (waste heat, radiative balance) make solar the inevitable long-term energy basis.
Solar Blows Other Flows Out Of The Water
- Peltan compares energy flows and shows sunlight (≈170,000 TW) far exceeds tidal, geothermal, and fossil fuel flows.
- He quantifies that an hour of sunlight equals a year's human energy use and years of sunlight dwarfs known nuclear fuel reserves.
Nuclear Can't Compete Long-Term
- Even burning all known uranium or mining the oceans can't match continuous solar input for long durations.
- Exotic sources like thorium or fusion extend timeframes but remain tiny compared to billions of years of remaining sunlight.
