Californian electricity from solar more than doubles

So in January 2013 (mid winter in the northern hemisphere) it was 1000 mW.  By January 2014 it peaked at 2500 mW (notice virtually no fall in production in the northern hemisphere winter) By May, it wasnearly 3 times as much as May 2013.

All the same, as the article where I found this striking graphic shows, for the US as a whole, CO2 emissions increased.  Which is because, even though California is the world's 7th largest economy all by itself, the US as a whole is much larger, but it had a much lower penetration rate than Cal.  But that state has lead the rest of the US for decades.  What has happened there will happen across the sunbelt, and eventually, as solar costs drop, everywhere.
