San Francisco alone consumes 850 continuous megawatts of electricity during the day. How much is that? The two supersized solar arrays planned for 2013 won't be enough to run SF — they'll produce 800 megawatts total. Gavin Newsom's pet project, the tidal power generator, will only piddle out 55 megawatts — one-fifteenth of the city's needs. Meanwhile, the Golden State's two operating nuclear sites each crank out more than 2,000 megawatts — day or night, high tide or low. What really drives the greenies crazy? They're safe.An FYI for everyone terrified of nuclear power: Chernobyl can't happen again. The RBMK model reactors — only used in Russia — were retrofitted for better control, containment and mitigation years ago. Three Mile Island, in hindsight, turns out to be a classic media scarefest. A post-action review at MIT found that "The melted nuclear core was contained and any radiation released was minimal. Thus, the plant design and safety protocols actually worked, despite numerous operator mistakes." Thirty years later, Westinghouse has designed a nuke that doesn't even need backup generators to stay cool if there's a power outage. We should be worried about nuclear waste disposal, not a China Syndrome-style meltdown. Nuclear waste processing has been engineered for the type of waste (LLW, MLW and HLW) that has been produced and effectivestrategies are working successfully right now. The real problem is that people gladly use the electricity cranked out by nukes, but freak out if there's a waste site within 2,000 miles of their backyards. Meanwhile, I wonder how many greenies know that fossil fuel releases radioactive material when burned? Uranium ore and other radioactive material are stored naturally in coal ore, from which America still gets about half of its electricity. Compared to the old choke factory at Hunter's Point, Diablo Canyon sure is pretty.
