Seven percent of what? Overall, averaged out? The issue is balancing currently sunny and currently windy places with those that are currently calm and currently dark.

Is it possible to build enough renewable energy to power the entire world? How much wire does it take to transmit enough electricity for North America over 3,000 miles to Europe and Asia (and back). How much wire to transmit from North America to South America and from Europe and Asia to South America? Is it possible to build a power wall for every home, business, government office, house of worship, and charity in the world?

What good are solar and power walls in the Arctic and Antarctic? Solar would be fine in the summer, days are long, but can power walls last throughout the winter? Can they generate enough electricity in the summer to store for the winter? Four million people live in the Arctic Circle.

If we manage to power the world with renewables and power walls, how will we replace them in twenty or thirty years?
