______energy is obtained from water falling through great heights to turn turbines which drive generators to produce electricity.

Explanation

**Step-by-Step Solution:**

1. **Understanding the Concept**: The question is asking about the type of energy that is generated from water falling from a height. This process involves converting the potential energy of water into kinetic energy as it falls.

2. **Identifying the Process**: When water falls from a great height, it turns turbines. The movement of these turbines is what drives generators.

3. **Connecting to Energy Production**: The generators convert the mechanical energy from the turbines into electrical energy. This process is commonly used in hydroelectric power plants.
