Electricity is planned. With wires, not some powder. So I imagine there will be ways to generate this electricity as you mentioned. But I think nuclear is going a step too far.
Some form of power lines will no doubt be added and possibly something like a transformer used so you don't fry your household appliances etc.. Would be great!!
Water is planned also, what form it will take, well we shall see. There has been talk of piping and pumps etc.. so it would be very interesting to supply your house and farm etc.. with pressurized water. Also for certain machines if added. Anyways, as for most things, just wait and see what comes. Might want to do some searches to see what has been brought up already and do some posting in those threads.
