  •  One issue I didn't see addressed (4+ / 0-)

    was the impact of large scale storms. When you have distributed generation and a 3x over capacity for generation, small storms that shut down wind generation in certain locations aren't that much of a problem.

    However, if you get massive storms that blanket a good portion of your generating area, you're really going to start stressing your cross-country interconnections.

    It was clear they simulated a certain amount of 'weather' over the course of 4 years, but it wasn't clear whether they included off-normal events, like hurricanes, to see if their system could maintain electricity production.

      ....stagnating high pressure centers, which will leave most of your billions of dollars in wind energy investment at a very small fraction of capacity over potentially very large regional areas.    

      The article mentioned in the diary presumes the existence of a significant electric utility battery storage that isn't in place and will be quite expensive to install.

      While marrying wind and solar to energy storage should be in our future mix, it is not in widespread implementation and most energy projects now being developed do not have such capability.

      would ease some of the problems associated with AC transmission.

      german wind farms out there have done perfectly well. those turbines are hella big.

      •  The turbines shut down (0+ / 0-)

        when the wind speed gets too high. Germany survives because it's not relying on that power, and it can also get power across its borders (and sell power when it produces too much).

        So, the comparison isn't really good for a 99.9% renewable USA.
