I can see it both ways. I think people who follow this stuff closely understand it without even having to click on the article.
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.
