The energy. obtained from the rising and falling oceans waves that is used to generate electricity at a wave power station is called - energy.

Explanation

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the type of energy obtained from the rising and falling ocean waves that is used to generate electricity at a wave power station.

2. **Identifying the Energy Source**: The energy derived from the movement of ocean waves is specifically related to their mechanical motion. As waves rise and fall, they create mechanical energy.

3. **Mechanism of Energy Conversion**: At a wave power station, the mechanical energy generated by the movement of the waves is converted into electrical energy. This is typically done using turbines that harness the energy from the waves.
