Which one is renewable energy source?

• Nuclear

• Geothermal

• Coal

• Natural gas

The diagram shows how electrical energy is produced.

What does Q represent?

• The water is heated until steam is produced and the turbine is rotated.

• The water rotates a motor, which will then rotate a generator.

• A mixture of steam and gas is heated until they expand and the turbine is generated.

• The water rotates a turbine, which will then rotate a generator.
