Visible light that is not converted into electricity strikes the surface of the planet and produces heat.Exactly. It doesn't heat the planet by striking the surface.
It heats the planet in different ways.
If you want to discuss waste heat then you are going to have to say that you believe that 100% of the electricity that is used (including electricity that was used to perform work), heats the surface of planet just like sunlight striking the surface of the planet.
Because until you say that, there is nothing for me to argue against.
