Negative prices aren’t necessarily a good thing because they tend to curb investments. A Reddit comment explains it well: https://www.reddit.com/r/worldnews/comments/1didv4q/comment/l938q2a/
Edit—I forgot the most important bit: Obviously that doesn’t mean that we should invest less in renewables, but that we should invest in large-scale battery research like yesterday.
I can tolerate ads, but I still wish we had a better financing model for content on the internet at large. Ad tech has a tendency to creep into places where it doesn’t belong. Like task bars, or explorers.
