Hi all, first post here 
I am on my 2nd game with Warlord difficulty now, doing fine so far. I got my a*s handed to the AI in my first game as I hav no idea what to do in civ4.
I have just built a factory, which the description says "provide electricity" and +25% shield. Thats ok, i got the +25% shield fine. Now I got the option to build Coal plant (I think nuclear plant as well when I finished the fission research), what do these plants do ?? The description didn't mention anything about the +shield% modifier, it just mentioned something like "provide power with coal ?". What does that means ? Do I need to build it?
2nd question that follows:
If i got both uranium and coal resources with me, do i need to build both nuclear
and coal plant , does their effect stack ?
Thanks
