> solar becoming the world's primary source of energy
Solar has always been the primary source of energy, Something like 99.95%, with geothermal taking 90% of the rest and tidal being basically zero
- leonidasrup 6mo agoYou can look at coal, oil, gas as form of compressed solar energy, because all of them have biological source, stored millions of year ago. It's just burning coal, oil, gas has nasty side effects. " Volcanic coal-burning in Siberia led to climate change 252 million years ago. Extensive burning in Siberia was a cause of the Permo-Triassic extinction " https://www.nsf.gov/news/volcanic-coal-burning-siberia-led-climate-change https://www.nsf.gov/news/volcanic-coal-burning-siberia-led-c...
- ilogik 6mo agoWhat about nuclear?
- guepe 6mo agoFuel was created by the explosion of supernovae, still solar but not our sun.
- pfdietz 6mo agoProbably neutron star collisions, actually.
- philipallstar 6mo agoIf it's not our sun then it isn't solar.
- triceratops 6mo agoPedantry I can get behind. Cheers

- Lambdanaut 6mo agoBy that logic, all of the Earth and the moon were once parts of stars, so tidal and geothermal are also solar. When people say "solar energy", they are usually referring to first order solar energy, directly from photons, not second or third order solar energy after it has been trapped into other sources of potential energy.
- eqvinox 6mo agoTidal kinda isn't solar since it's from rotation's and orbits' energies though.
