Again... incrementally there is no change in waste heat from replacing fossil fuels with solar. Electricity usage and what waste heat there is stays the same regardless of the generating source. But solar radiation absorbed by the surface of the planet is different depending upon the generating source.And more heat being radiated by light bulbs, microwaves, toasters, TVs, coffee makers.
Anything that used the electricity.
You have to do all the math, not just half of it. That's what liberals do.
