3.3 Text: How energy is produced? (1) Grammar: Past Simple (Irregular Verbs) Tasks

1. Have you ever wondered where the electricity in your house comes from? Read the texts about the different types of power plants and match them with the picture.

1 Nuclear power plants

About 10% of the world's electric power is produced by nuclear power plants. Nuclear power requires little fuel and causes much less air pollution than other power plants, but it can cause severe health and environmental problems when accidents occur, with a consequent release of radioactive material. This type of energy is produced by the splitting of atoms of uranium, which releases heat. This process - called fission - produces large amounts of steam, which is used to turn the blades of turbines thus creating energy. The main problems with nuclear power are linked to the location of the power plants, as people are not willing to have these plants near their homes, and the disposal of waste material, which stays radioactive for centuries.
