Ten percent of the electricity generation in US now comes from wind and solar

It's seven percent annually, 10% for one month. (This is covered slightly better in Ars Technica.) Spring and autumn have lower energy use because less heating and cooling is needed, and wind works particularly well at those times, so the ratio is better than the annual rate at those times.

I think we are at the early stages of another major "disruptive" event. In 20-30 years fossil fuels could be obsolescent. I'm sure everyone realizes how incredibly destabilizing this will be to the world economic order among other things.
