SINCE I AM a Christian, I worship the Son, not the sun. That said, I’ve been spending most of my time lately thinking about that large ball of gas the good Lord was kind enough to hang in the sky, 93 million miles away. In fact, we’re getting ready for an entire weekend devoted to considering the most important object in our physical world — though it is the only one you can’t look at directly. SunDay will happen on September 20 and 21, 2025 (details at SunDay.earth), and I hope it’s a chance for real reverence.
The sun already supplies light, heat, and photosynthesis, and now it’s ready to provide all the power we could ever need. In the last decade, engineers have dropped the price of solar power by 90%; they have done similar work for batteries that store power for when the sun goes down. We now live on a planet where the cheapest way to generate power is to point a sheet of glass at the sun.
If we take full advantage of those new facts, we stand some chance of limiting the damage from the climate crisis. Last year, California reduced the amount of natural gas it used to generate energy by 25% compared to its usage in 2023. This is the most hopeful statistic I’ve come across in my 35 years of working on global warming. California was able to do this because it had put up enough solar panels to really make a difference. And this could happen everywhere. Texas is currently building clean energy faster than anywhere else in North America but is miles behind China, which put up about 60% of the planet’s solar panels last year.
