California's shift toward renewables makes energy harder to manage
California's electrical grid has a problem - a nice problem, but a problem nonetheless: The state often has too much power.
Adding renewable energy to power grid requires flexibility
Solar panels, wind turbines, electric vehicles and other green power sources are proliferating rapidly, but their reliable integration into the existing electric grid is another story.
