Profit and Experience per Energy[]
This building and the Emergency Clinic 3 have the best energy harvesting bonuses in the game. There is a 50% chance of getting energy back, and 20% of the time you get more energy back than you spent. If you were to collect from this 100 times, you would get 30 single energies, 15 2x energy, and 5 4x energy, for a total of 80 energy back! On average, it costs just one energy per 5 collections from either building.
Because of this tremendous energy bonus, high profits can be gained per energy spent, especially if collected en masse to fill your Bonus Bar. The exact profit per energy varies depending on your level.
For the same reason, this is also a great way to gain experience. Again, on average, 1 energy gains you 5-10 experience. There are few other ways to gain experience this fast.
Compared to the Emergency Clinic 3, this building drops zoning permits, which are arguably more useful than ribbons. Also, it allows 50 population more than the Emergency Clinic 3.
