Re: ‘Calif. needs to reconsider its electric avenues’ (Metro, Aug. 15-18)
Letter writer Sean O’Rourke’s argument that radios and computers require AC is specious; I don’t know about him, but between my computer and the wall socket is an AC-to-DC converter.
He quibbles about inefficiencies in AC-to-DC conversion while blithely ignoring the waste and inefficiency in mining coal/pumping oil, transporting it, burning it to make steam and using the steam to turn a turbine in order to generate electricity.
When you add up all the waste inherent in this process, solar and wind generation doesn’t look so bad.
If Nicola Tesla, George Eastman and Thomas Edison adopted the attitude that “if it’s not perfect, we shouldn’t do it,” I’d be reading your rag by a whale-oil lamp.
