Totally unnecessary : I did the Math to cross-verify - Elon Musk is 100 % right !
Just ONE square mile of batteries and a TOTAL of 100 x 100 square miles of Solar can power the entire USA 24/7. Area required will be much lesser for Canada.
How convenient for Musk that technology connections did this exact topic and these exact calculations (and much more) as a topic months and months ago: https://youtu.be/KtQ9nt2ZeGM?is=wOjIwPKFuYj2Smrh
Why up Musk? Is he your primary source of news and ideas?
