Any downsides to wind turbines / water towers?

Seems like they just give free money every week. ANy reason not to fill a few corners with a bunch of these to boost up my income?

Diminishing returns, hidden maintenance, anything?

not that I have found aside from the amount of money you get extra is capped

From what I've observed, they only serve to reduce or negate the cost of paying your electricity/water bill.

So if you care about maximizing income, there's no reason to build more than the water and power draw your zoo is currently using.

Pros:

• Generates energy/water to offset cost of energy/water
  
• Can generate excess energy/water that is then sold for extra cash
  
• Are pretty cheap to buy
  
• Don't require maintenance- just buy and place
  
• Gives good morality points

Cons:

• The excess energy/water profit is capped per week
  
• They take up space you could be using for the rest of the zoo (especially the water towers)
  
• You need a lot of each of them when you get a bigger zoo to generate excess energy/water to sell

Since I'm doing a good morality run, I use both the wind turbines and water towers. They take up about half of a plot of land since I have almost all of the animals unlocked and most of the variants as well. I do wish that I could use that space for farming though, since I need a TON of some crops and my current big farmland plots are not big enough.... I need more space in general to keep everything/everyone happy.

Cool, thanks!

Any ballpark estimate on the cap?
