The electricity system is experiencing growing pains these days. But it's not only demand for electricity that's expanding — it's the sources of electricity, particularly unpredictable kinds, like wind farms and solar panels.

And grid operators know that we're just at the beginning. States are requiring more renewable power to fight climate change, and it may be the customers who will play a big role in helping grid operators manage these clean, but finicky, sources of power.

DAVID GREENE, HOST:

And whether it's worth paying to avoid all blackouts is a theme that has been on the mind of Steven Weissman, he's a professor of Electricity Law at the University of California, Berkeley. We reached him on this blackout anniversary to learn about how the nation's energy system is structured. Weissman says the grid is really made up of several complex networks.
