It’s been a while since I wrote a post reminding us all exactly how little area is required, in relative terms, to provide enough solar power for the entire world. Numbers are cool, but graphics are better. [Here] is a map that shows the swath that we’d need to take out of Northern Africa in order to get the job done.
We all need to keep the truth in mind as we contemplate the appropriate energy policy for Earth in the 21st Century, i.e., our planet receives 6000 times more energy from the sun every day than all seven billion of us can consume here. We have it within our grasp to transform ourselves into a civilization that pulls itself back from the brink of extinction by migrating to clean energy. Let’s do it.
