| - | By building a dam across a large river it is possible to create a huge store of potential energy, which can be tapped when needed by allowing the water to fall through the dam. |
| - | Falling water has energy which can be harnessed using a hydroelectric power plant. |
| - | This energy is usually harnessed using turbines, which are driven by falling water. |
| - | Water-driven turbines can power generators to make electricity. |
| - | Falling water is a renewable source of energy. |
