Comment on Can enough solar pannels decrease the global temps?

Directly, as you phrased the question: No.
Indirectly: Yes. Because we would automatically stop burning fuels when we get all our energy from solar. That would decrease the temerature a tiny little bit.
But the temerature of the planet does not really depend on such actions. For example, the indirect effects of CO2 and Ozone in the atmosphere have much more powerful impacts - and still they can only change the temperature at the planet’s surface. The whole of the planet is yet another thing.

Don’t forget industrial heat. If we had infinite electricity for free everywhere there would still be fossil fuels burned for industrial heat. We need more technology to finish it like plasma torches.
No need to despair, the technology is being actively developed and a lot of the sub 600 Celsius temps have an electric solution now.

Why? Is it different from “all of mankind’s energy”?
olafurp@lemmy.world 3 weeks ago
I assumed you meant electricity since solar only makes that type of energy efficiently (and sub 100C)

Over 600 might be able to use focused sunlight? Like the tower in the middle of a solar farm? Though seems highly impractical to effectively laser that heat somewhere
