Your first statement is 100% correct, there is no such thing a "clean energy"! Bravo! Sadly, I must disagree with your second statement, as solar panels do NOT bring any benefits for the world as a whole. The transition to "renewable energy" that so many misinformed environmentalists envision cannot possibly happen, because solar modules do not ever make as much power as it took to manufacture them. The real "energy balance" of PV power is profoundly negative, anywhere from 8x to 40x, and all of that energy must come from existing power grids. Haven't you ever wondered why NO solar panel factories are powered by solar PV? If you don't believe me, will you believe Elon Musk? The quote is real, the article is real, please go read it:
“Sometimes the solar roof is positioned as sort of a competitor to utilities, but we’re actually going to need utility power to increase and we’re going to need local power generation. Because if you transition all energy to electric, that roughly triples the amount of electricity that is needed.” - Elon Musk
