It's a pretty big milestone on the journey.
Non-renewables are going to be around for a very long time, as the sun and wind can't be turned up based on demand - but kind-of nice to see them relegated to surge duty, rather than the core of energy production.
But I have noticed an attitude among most non-news junkies of "I don't get why not everything is renewable - it literally is just as easy - must be bribes by oil execs". And I assume most non-news junkies who end up seeing that headline will assume it means California is 100% powered by solar and wind.
The only reason they couldnt stop this future was because the plunge in price was so precipitous.
