If we used all 173TW instead of letting it reflect back - what would that do for the temperature of the planet?

- vegai_ 4y agoThat's probably a bit absurd, and would probably cause a lot of changes since it would also mean that all the oceans are practically covered with panels. Here's a reference to a study about large-scale panel installations: https://www.science.org/content/article/solar-panel-shade-won-t-cool-earth#:~:text=The%20benefits%20of%20solar%20panels,we%20keep%20burning%20fossil%20fuels https://www.science.org/content/article/solar-panel-shade-wo.... They suggest that there would be an impact, but far less than the impact of greenhouse gases they could replace.

It will eventually become photons again and can leave back towards space, plus there is no release of greenhouse gases. I guess it would still do something for the temperature of the planet, but to a far lesser extent.
