Wind turbines at the Kahuku wind farm on Oahu's North Shore in 2011. Hawaiian energy managers are hoping to build stronger connections with customers to better manage renewable sources of energy on the grid.
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.

You're not likely to find many bankers wearing those old stereotypical green visors these days. But at U.S. Bank, some employees sport hairnets — at least when they're serving breakfast.
Every Friday morning, a group of U.S. Bank employees stands elbow to elbow at a Minneapolis soup kitchen, doling out French toast, sausage and other breakfast goodies. Most of the people getting free breakfast are homeless men who lug their belongings in plastic bags.
