Choose generators by the bottleneck they solve: starter Turbines and Small Dams help early power, while later sources only matter after the grid and city can absorb more output.
Compare Power a City generator choices without inventing exact output, cost, unlock, or tier-list data.
Use Turbine and Small Dam as verified early source names, then treat gas, geothermal, nuclear, and larger plants as transcript-observed candidates until you verify the exact in-game label and cost in your session.
Use the role cards as observed-data fields: name, cost, output, upgrade note, grid fit, and missing costs/rates/unlocks are visibly marked unknown until you check them.
