Letter: Any clean energy is free energy
Re: ‘Calif. needs to reconsider its electric avenues’ (Metro, Aug. 15-18)
Is the glass 30 percent empty or 70 percent full? Letter writer Sean O’Rourke said that with solar and wind energy, you lose 30 percent of the energy in the process of storage.
That means you gain 70 percent. Not bad, considering the ecological benefits.
