The most uplifting news from my POV: power from renewables is now less expensive to produce than power from coal in some parts of the world. So much so that perfectly good coal-fired power plants are being decommissioned because they can't compete with modern renewables. And the technological genie which enables these renewables cannot be put back in the bottle.

As the saying goes, people didn't stop riding horses because they ran out of horses; they stopped because cars were superior. You're seeing the same thing happen with renewables now. It's wonderful.
