Other Forms of Energy


Table of Contents :


Water power

Water power supplies us with about 6 % of global energy. When water falls from higher to lower places it creates the power to turn big turbines. Generators turn this power into electricity.

Water power plays a major role in areas where there are mountains and many rivers, like Austria, Switzerland and Scandinavia. These countries produce most of their energy this way.

It does not cause pollution and because water in mountain areas and rivers always flows we call it a renewable source of energy.


Nuclear energy


About 6 % of total world energy comes from over 400 nuclear power plants. When uranium atoms are split energy is set free and a large amount of heat is created, which is used to produce electricity. The process of splitting atoms is called nuclear fission.

When the first nuclear power stations were built in the late 1950s people thought that they would provide the world with enough cheap energy, but it turned out that fission had several disadvantages. Because power plants produce a lot of hot water they must have big, expensive cooling towers. Power plants also produce waste that stays radioactive for many years. It must be stored in safe places, for example deep inside rock layers where it cannot do any harm.

The nuclear accident at Chernobyl in 1986 showed us that radioactivity , when released into the air, causes damage to large areas and kills many people. Even decades after the accident thousands of citizens who lived around Chernobyl are still suffering from diseases caused by radioactivity.
