Without waiting for what are often moribund utilities to do the job, business and home owners are getting on with electrifying their lives, and doing it cleanly.
But nothing beats the idea that solar panels are suddenly sprouting, as if by magic, precisely where they’re needed most. If we can get there fast enough—before we’re overwhelmed by droughts and floods—then a sunny new world is entirely possible.
