> Decentralized doesn't work so well for places that require a high ratio of electrical power to solar radiance Yeah, another example that comes to mind are flats - the roof is a bit small to cover all residents' energy needs. As always in life it seems that "it depends" but I think you are right about remote places. It is of course always better to have electrical grid since you shift the maintenance to someone else (as long as the power delivered is reliable and cost effective). The one issue I can think of is current grid may not be able to handle many small energy producers - they can be cut off when peak power is a problem. In those cases individual prosumers would benefit from having a local battery storage system that fit their needs, even when connected to the grid.
