Given that power, in its three forms (ADM,DIP,MIL), is so very important in EU4, I wanted to have a discussion about all the ways of raising your monthly gain of power.
1. Your ruler: The base stat comes from your ruler's ratings. Not too complicated here.
2. Advisors: Every advisor raises one of the power stats, according to their skill level - up to 3. Choosing a more expensive advisor, therefore, is one of the ways in which you can trade money for power.
3. Buildings: After looking at the code, I was surprised to find that every building, like advisors, raises a particular power stat. As there is no skill level involved, it would seem each building only adds 1 power, so this provides a way for larger nations to trade money (in one-shot form) for power. The potential gain for a large nation with money to burn is pretty staggering. I can't tell if any later buildings replace older buildings. Note that most buildings are destroyed on conquest (which I assume means on transfer of ownership, rather than mere occupation), so you don't get a power boost by capturing previously built-up provinces.
I've built up a modifiers list from the code, and there don't appear to be any that affect power gain at all, so what you have is what you have, with no way to multiply the effect - unlike virtually every other game stat.
