Listen carefully, Bozo. When we talk of "green energy" "renewable energy" or "sustainable energy", we're talking about an energy source that's not depletable. In other words BY DEFINITION wind energy, solar energy, hydro power in a variety of forms, are all forms of sustainable energy. Their source, and thus the potential to convert that energy to usable power will NEVER be depleted.
Why is that so difficult for you to understand? It doesn't have anything to do with price, cost, risk of investment, production materials or infrastructure that's needed for it to be useful. If you want to make that argument, you'll have to do so in terms that are clearly far beyond your ability to articulate.
You didn't start this thread to challenge me or to expect me to demonstrate my experience, you started this thread because you made a fool of yourself on the other one, got spanked properly, and hoped this time others would come to your rescue. Well they didn't. Once again you're caught with your pants down doing your crybaby act, with nothing but a red ass to show for your silly effort. I constructed solar homes. You can't construct a complete sentence except by pure chance, let alone a coherent thought.
I'm done with you. Go ahead give me your last limp-wristed insult. Make it good.
