Windmill is used to produce electricity. Which of the following is the sequence of energy conversion in a windmill?

Options

A. `Wind energyrarrelectrical energyrarrmechanical energy`
B. `Electrical energyrarrwind energyrarrmechanical energy`
C. `Mechanical energyrarrwind energyrarrelectrical energy`
D. `Wind energyrarrmechanical energyrarrelectrical energy`

Answer

To determine the sequence of energy conversion in a windmill, we can break down the process into clear steps:

### Step-by-Step Solution:

1. **Wind Energy**: The process begins with wind energy. When the wind blows, it carries kinetic energy.

2. **Mechanical Energy**: As the wind moves, it causes the blades of the windmill to rotate. This rotation converts the wind energy into mechanical energy (also referred to as rotational energy).

3. **Electrical Energy**: The mechanical energy generated by the rotation of the windmill blades is then converted into electrical energy through a generator connected to the windmill.

### Final Sequence:
Thus, the correct sequence of energy conversion in a windmill is:
- **Wind Energy → Mechanical Energy → Electrical Energy**

### Answer:
The correct option is that wind energy is converted first into mechanical energy, then into electrical energy.
