Oct 21, 2020 at 7:40 | comment | added | Luaan | @TCooper Hydroelectric would be entirely dissipated as heat, ultimately radiated at very long wavelenghts - there's potential to decrease the temperature increase from that. Wind is trickier - it depends a lot on how wind plants affect atmospheric mixing an all that, and I haven't found any nice studies of that in a quick search. Photovoltaics are probably the worst - they take short wavelength radiation and change it into long wavelength, which means it takes longer to re-radiate back to space, not to mention that the atmosphere is pretty transparent to visible light. Solar thermal are best. | |

Oct 21, 2020 at 0:15 | comment | added | user65081 | @TCooper my comment meant that any green energy would have ended up wasted into heat by friction, or absorption/reemission. So using more green energy should not contribute much to global warming. | |
Oct 20, 2020 at 23:32 | comment | added | TCooper | @Wolphramjonny Doesn't your question's answer depend entirely on the source of energy? Solar isn't the same as hydroelectric isn't the same as wind isn't the same as natural gas isn't the same as coal isn't the same as... you get the idea. i.e. hydro electric would mostly just be maintained as kinetic energy with little to no change in heat, solar would be almost strictly heat, I have no idea for natural gas... please correct me if I'm wrong but I think you've oversimplified. | |

Oct 20, 2020 at 13:40 | comment | added | Matthew | So, your solar panel converts sunlight to electricity, which is eventually converted to heat. Just what do you think was happening to that sunlight if you didn't convert it to electricity? | |

Oct 18, 2020 at 22:04 | comment | added | user65081 | what would have happened to the same energy if it was not "wasted on heat" by humans? | |
