With all the new information recently, I was wondering what will happen in the age of electrical power in the end game. Power has been part of the Civ series for some time now so I anticipate it will remain in some form. Currently in Civ4 one resource of Uranium or Coal means that with a power plant any city can have power. Not only is this unrealistic, it is also strategically shallow and I think that by making Uranium and Coal strategic resources with respect to power then one could see them being an important aspect of the end game. For example one coal resource could power 5 cities with power stations, uranium 10, etc. Is there any current information that could support or detract from this idea or is it still an unknown?
