[Hydropower dams](https://www.materialinsights.org/energy/e_hydro_dams/) (energy) and [Water cycle](https://www.materialinsights.org/energy/e_hydro/) (energy): 1 relationship.

## How they are linked

### 1. Energy flow

*Physical flow · 94% of flow · Water cycle → Hydropower dams*

Dams hold back river water so its fall can drive turbines.

- **94%** of Water cycle's energy goes this way
