alt Hacker NewsI have the feeling that particular energy output does not so much, really. For example this plant in the image is about 700x400m and when multiplied with the suns peak output you already get a potential energy of 280MW. And this site almost triples that. The sun shines practically everywhere, though.
Humans produce about 20TW globally at this time (ChatGPT), while the sun adds about 174000TW of energy to the earth.
I guess you could argue that our waste heat does something, but I think the greenhouse gases that trap this enormous energy more effectively have a far bigger effect.
I think that works out to 0.01%? There's some hand-waving around solar radiation in the atmosphere vs. on the surface and double counting some that goes to solar power, but the number looks smaller than the variation in solar output over the solar cycle.
