Not free, as is right now with my accumulated 200 AE and power costs being increased by 200% due to that AE it will be a long time before that "free" real estate can be grabbed. Adding to the fact that I'm not in the top list of people with inventions and that civic power is used for both inventions and relocating pops ... the inventions take priority. Pops can always be taken from other places if necessary, if you catch my drift
But inventions don't come from anywhere else.
It also so happens that I wasn't aware of some changes being made so I spent all of last session without the matching ideas bonus power generation, leaving me pretty dry on that front.
