I was actually thinking of cases in which storage is limited, or in places where, for instance, that tend to get less wind. As for the energy storage issue, while storage technology has gotten much, much better, I don't think we're yet where we need to be to completely move over to pure renewable. I admit, though, that I am not an expert in energy storage, so I could be totally off on this.<p>All else aside though, wherever there is a choice between technologies such as coal and technologies such as nuclear energy, I think that the latter needs to be very seriously considered.
