Nuclear power

is a dangerous, dirty and expensive way to essentially boil water. More than 7 million people live within 50 miles of San Onofre, a plant that has suffered problems that, four months later, still have experts scratching their heads as to what caused them, not to mention how to solve them.

California can and should move beyond nuclear power. In fact, it already has 1gigawatt of solar power on rooftops throughout the state, putting California roughly a quarter of the way toward replacing nuclear power with sunshine.

Other renewable energy technologies — including wind and biomass, along with proven energy efficiency and conservation measures — will enable California to keep the lights on, save ratepayers money and protect the health and safety of its residents. Bernadette Del Chiaro

Thanks for the editorial clearly assessing San Onofre’s future. Southern Californians must face the truth about an aging nuclear power plant in a region vulnerable to firestorms (like the one that hit Laguna Beach in 1993) and earthquakes (the weakened plant was only ever guaranteed against a 7.0 earthquake nearby).

With good planning, we need not face rolling blackouts; nonetheless, it’s far better to be a little dark or hot than to have from Oceanside to Laguna Beach a “no-go zone” because of accidents such as the ones at Fukushima and Chernobyl.

When asked recently when humans might be able to inhabit the Chernobyl site again, the nuclear plant’s director said, “At least 20,000 years.” A nuclear mistake is not an inconvenience; it is forever.

The San Onofre problem seems almost unsolvable. Not enough time remains in the approved licensing period to make a redesigned steam generator pay for itself. New baseline data make protecting against seismic risk a greater challenge. There’s still no solution for the permanent storage of toxic waste. The editorial’s suggestion to redirect funds to more renewable energy is not really a solution.

But this all assumes the demand side will be business as usual. It won’t be. Diminishing global oil production will be the new norm. That will mean decreases in economic activity, wealth and demand for electricity.

This may not sound like a desirable outcome, but it is realistic. It reflects an awareness of geological constraints. All long-range planning should be done with that reality in mind.
