In California, there is so much solar energy that grid operators have to switch off solar farms. One solution of dealing with the additional power generated is to share the renewable wealth across state borders – but in the West, it's sparking some not-so-neighborly opposition.

Nancy Traweek's job is to balance California's electrical grid at the California Independent System Operator (CAISO), keeping the lights on for 30 million people. She relies on huge natural gas power plants that put out a steady stream of electricity.
