That's amazingly useful to know!!! Thanks!A nuclear plant has a chance to meltdown if the city riots two turns in a row...
Hoover dam is clearly the awesomest choice unless you want the 100% of a nuclear plant, and that can be put in select cities.I always use hydro or solar (curse my ecological/ethical mind) although they cost more, it always helps to never worry about pollution or a meltdown.
Tip for noobs: NEVER USE A COAL PLANT!! take it from one who learned it the hard way.
I do have to disagree with you on the coal plants though. You get them right away. If you have high production cities I suggest building coal plants in those cities. Remember that you can sell them as soon as you finish an alternate plant.
I don't know how you play, but I generaly have a few extremely high production cities, which don't share tiles with any other cities (or claim any shared tiles), and have lots of grassland and hills. I never wait for hydro plants for these cities.
The key here is that before sanitation there's no way you can utilize more than 12 tiles (besides the center). That leaves a whopping 8 pollutions before you lose production.
Well, Coal plant cause a smattering of pollution which eventually turns counter-productive. Even with my usuall worker army cleaning the pollution up, a coal plant's pollution usually makes production worse than before I built it
Coal And Nuclear Are The Best Of All, Others Are For Ladies
