If the power grid in California is going to evolve to meet the needs of the state, then one of two things need to happen: people need to pull their heads out of their asses and realize that coal power is nowhere near as dirty as it was even 15 years ago (and *that* was a far cry from the level of pollution produced 50 years ago by coal), or they need to understand that the wind generators need to go somewhere and find a way to build it into the landscape.
I think you are missing the point. All of this talk about building generating capacity is irrelevant if the power distribution grid cannot deliver the power to where it is required. That is what the article does not say, the piece of wire between the power plant and your house can only deliver approximately 30% of the power an electric car infrastructure will require.
For a moment think about what is happening. The kilowatts, per vehicle, once delivered by oil is delivered by wire. I however cannot speak to the sanity of sitting in a traffic jam for hours of the day but if we maintain this "way of life" ALL of that infrastructure HAS to be upgraded if people are to charge their cars at home and if parking stations are to be equipped with charging facilities.
Keeping in mind that I'm an environmentalist myself when I say this... the reason that the power industry in California hasn't moved at the rate it needs to is because of the enviro-nazis blocking the construction of nuclear and coal plants
Keep in mind that I am an advocate of deploying Nuclear Power responsibly when I say this ... the reason the Nuclear industry hasn't expanded is because it is rife with Basis Design Issues when deploying new plants. The NRC commissioned Nuclear plant manufacturers (Westinghouse, General Electric, Bechtel, Sargent & Lundy, Northern States Power and Commonwealth Edison) to come up design recommendations to improve the safety of the plants but the AP-1000 incorporates none of the design changes the industry *itself* recommends be applied to reactor facility design. This has nothing to do with anyone or anything other than economic reasons and design changes made to produce the AP-1000 design are there to make Nuclear plants cheaper to build, but they are still expensive. Coal plants are a completely different argument and can be built with the standard 40-50 year finance plan that these plants are built with as the risk affecting return is different. Yes a modern coal plant is more efficient but it still produced a lot of carbon externality.
If anything a decentralisation of the grid will reduce the *cost* of the upgrades required to deliver the current to charge electric vehicles. I doubt there is any party who won't benefit from evolving the grid as the time has certainly come to drive efficiency into it for many other reasons. Our society is encountering growing pains. Our society either adapts to these changes or it withers. The status quo has to change and the opportunity we have now is to create more balanced lifestyles that takes the pressure off our infrastructure.
Every transaction our society conducts costs energy and you must have the means to *deliver* that energy to where it is required. Until we reduce and balance the energetic costs required to run our society we will continue to encounter these types of problems and building new power plants is analogous to printing money in this respect. Quite simply humanity has choice of sustaining growth or growing sustainability.
