The San Onofre plant was designed to withstand a 7.0 quake
Considering the largest quake California ever had was a 7.9 I don't think 7.0 is enough lol.
A good point Lynn made is how much energy it takes to make something like an energy efficient alternative. Too often I hear people pushing ideas to save from oil usage when it actually can take more oil then it saves. You always need to look at the whole picture. Take incandescent light bulbs for example. The ban in America is in place and the bulbs have deadlines for when they are illegal. Those light bulbs though are made in America. You think it is more energy efficient to ship 200 pounds of fluorescent light bulbs in a 8000 pound cargo container thousands of miles over the seas from China? In the end it will use more energy then it saves.
