RoboGobo - how does MetroPet Island survive with only one power source??

Just watched one of RoboGobo's Christmas episodes - and MetroPet Island lost power when Pupsicle froze the water from the mountain that goes through the water wheel to power the island.

How do they survive with just one power source? They didn't even consider solar, fossil fuels, etc.

Yes I know it's a preschool show - but how can they survive when the villians can do stuff like this?
