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.

Switched On is hosted this week by Mark Taylor.
