True, their growth rate promises to be astronomical (Jones wouldn't agree ;) > The major impediments > to going all solar are bulk energy storage, i.e. large battery or > hydrogen generating systems, and low cost energy transmission systems. Storage is improving, latest lithium ion batteries for electric cars with tens of thousands of cycles lifetime e.g. altairnano seem promising, couldn't utilities give rebates to customers accepting to store energy for them in their sometimes underused car batteries? As for transmission, what's wrong with current electric power transmission lines? Michel
