Here's how it works:

1. Burning Coal: Coal is burned in power plants, releasing heat energy.

2. Steam Production: The heat converts water into high-pressure steam.

3. Turbine Rotation: The steam drives a turbine, which spins a generator.

4. Electricity Generation: The spinning generator creates electricity.

While coal is primarily used for electricity generation, it can also be used for other forms of energy:

* Heat Energy: Coal can directly provide heat for industrial processes and heating homes.

* Mechanical Energy: Coal can be used in steam engines to power machinery.

It's important to note that coal is a fossil fuel and its use contributes to environmental problems like air pollution and climate change.
