Please do tell, how much wind mill and solar panel would it take to power all of our houses and cars? Secondly, what would happen if you put that many wind mills and solar panels in place. I’m not even talking about the financial cost. Just the pure size. Then there’s other unintended consequences, such as changing the wind pattern and killing endangered birds. Lastly, China and India alone has 9x more people than US. How many windmills and solar panels do you think would be needed to provide enough power for all of those people if their living standard matches us?
