Would 80% be ideal? I would imagine Solar would start getting iffy over 50%.
Presumably you want a lot of hydroelectric, wind, and nuclear so you don't need a lot of batteries, and you have enough sources of power when the sun isn't shining.
Maybe I'm being un-imaginative - but is anyone envisioning a global energy grid so we could have solar energy from Australia and Sahara shipped to North America during our night - and back to Asia and Europe from the Southwest during our day??
