Supplies of coal, oil and gas are running out. These fossil fuels are a finite resources that will never be available again when we have consumed them. They are said to be Non-

renewable sources of energy

Renewable Sources of Energy are

those which will not run out.

They include:-

1. 1. Solar Power

2. 2. Wind Power

3. 3. Wave Power

4. 4. Tidal Power

5. 5. Hydroelectric Power

6. 6. Bio-fuels

7. 7. Geothermal Power

Solar PowerSolar Power There are three main methods of harnessing the energy arriving here from the sun.

Solar Cells — these devices convert the light energy from the sun into electrical energy. They are commonly found powering calculators but they are still expensive and you need many of them to produce a significant amount ofelectrical energy.

Solar Panels — these are used to heat water flowing though pipes on their surface. The heated water can be used for

washing or for warming buildings.

Solar Furnace — these use mirrors to concentrate the energy into a small area. Small ones can be used to cook food in third world countries.

The light and heat energy radiated from the sun provides us with SOLAR POWER

Wind Wind POWERPOWERWinds are caused by air moving from place to place due to differences in air

pressure. Moving air has a lot of kinetic energy that can be harnessed using windmills

The kinetic energy can be used directly to drive water pumps or turn mill wheels to grind grain.

Other windmills or aero-generators can be used to produce electricity when the winds kinetic energy is used to turn a generator.

One windmill on its own can’t generate much electricity—if we put up lots, we call it a

“Wind Farm”. Here is a picture of one . . . .


Wave PowerWave Power


Waves crash onto seashores with thunderous power on thousands of miles of beaches all around the world.

Using floats called “ducks” which move up and down when a wave passes, scientists are trying to harness this massive power source. There are other ways of harnessing wave power – at the end of this show your teacher might let you try and find out about some of them if you ask them nicely.
