“It’s tough to make predictions, especially about the future,” quipped Yogi Berra. I keep his wise admonition in mind as I make predictions about our energy future, but we have many reasons for optimism when it comes to the future growth of solar.
Here’s the summary: solar is taking over. We can now see many years into the future when it comes to energy. And that future is primarily solar-powered.
Why am I so optimistic about solar’s prospects? Well, let me explain.
The “solar singularity” will, by my definition, occur when solar prices become so cheap that solar becomes the default power source based on cost alone. We aren’t there yet, but we’re probably just a few years away from that point, particularly since energy storage costs are already declining strongly. (I’m not going to address storage in this article further, but, of course, a grid can’t run on variable solar power alone, so we’ll need storage and other backup technologies to ensure reliable grids as solar power penetration grows.)
