We all know wind and solar are intermittent -- at some point the sun stops shining and the wind stops blowing. But is wind and solar power reliable? The answer seems to be that at least with a battery, yes, it is. This week Switched On speaks with Nat Bullard, chief content officer for BloombergNEF, about the future of renewables on the grid. We discuss renewables reliability, competitiveness of gas peakers in a renewables-plus-storage world, and what to do with old wind and solar farms.

This episode is based on the weekly Sparklines series from Bloomberg Green, by Nat Bullard.
