“California utilities are struggling to integrate the abundant solar energy now produced. At peak times, they’re forced to shut down renewables or offload energy to other states because there’s not enough local demand.

That may include batteries and large- scale pumped storage, in which excess solar energy is used to pump water uphill. The water is released and flows through hydroelectric generators.”
