does nothing but make things warmer The heat would radiate into space if it were not for greenhouse gasses reflecting it back to the surface.

>>100% I think there may be humor there ... *<8o) Indeed - my discussion was really narrow and only about solar panels heating locally - and of course all those watts - whether used to warm water or drive a car go into the entropy pool of waste heat. There is an environmental impact - that's all I'm saying to a non-Republican. Here's what I say to a Republican. I am totally pro-solar but for my house I've not taken the plunge because I think it is more suitable for grid scale now. People off the grid or who want some self-reliance for one of many reasons it may make sense. Having people climb on my fragile - but intact roof - may cut into the ROI. I had to glue together a tile from the painter's eff up. I see perovskite cells as being the killer app for scalable large scale solar - dropping the price even more and opening up whole new areas of application on building surfaces - even houses - replacing silicon with room temperature, low-complexity, low-toxicity strip mall or sole-proprietor processes. Printable atom thick nanoparticles that need no exotic materials - sure, they use tin but because they are so thin - this is an infinitesimal compared to its widespread industrial use. If a fraction of a gram of tin could make many tennis courts of solar panels - and IF there was a recycling program- we'd be far better off than the incidental release through other mechanisms such as coal. When I first wrote this last paragraph I'd forgotten about the tin replacement of lead with tin as a recent advancement and was going to have the word "lead" everywhere I used "tin" above. It would STILL be an improvement even with lead. science.org
