The San Onofre nuclear plant has been shuttered for nearly a year. Regulators closed the plant in January after discovering a steam generator tube had leaked a small amount of radioactive gas.
As energy investigators decide the future of one of the state's biggest power sources, grid operators have patched together ways to replace the lost power, like by bringing back online a decommissioned gas plant at Huntingon Beach.
Now a think tank that focuses on alternative energy sources has released a new report offering long-term solutions should San Onofre be taken off-line permanently. The Rocky Mountain Institute, based in Boulder, Colorado draws strategies from around the world, including last year's Fukushima nuclear crisis.
The institute's program director James Newcombe joins the show to tell us more.
