Back in June, I wrote a post on how solar and wind cannot sustain an urban and industrial civilization. I used ten photos of the largest cities in the world to make my point. I think that was a good approach. Most people identify well with graphics and pictures.
Now, some folks have done the math on going completely solar in the US. I think it’s worth a read.
The number of solar panels and batteries to accomplish this purpose is astounding and ultimately not possible (based on my assumption that mass genocide is not allowed as part of the goal to go 100% alternative energy.)
