PowerPoint on Renewable resources

Answer the questions below using the PowerPoint as a resource.
You may NOT copy and paste. Type the answer. Use your own words.

Refer to slide 2

List 7 different types of renewable energy resources together with their source.

Refer to slide 4

Explain how solar power stations generate electricity.

Refer to slide 5

Tabulate 4 advantages and 5 disadvantages of using solar power.

Refer to slide 6

Complete the missing words:

Unlike fossil fuels and solar energy, there is no need for a b_______ in a wind turbine.
The wind turns the turbine d_, no s_ is required.
Wind energy is very l _ power so you need many wind turbines to meet the same energy requirements as a fuel-burning power station.
You need to find an a large a__ of land, away from settlements because of the n_, and it obviously has to be w_________!

Refer to slide7

Tabulate 4 advantages and 6 disadvantages of using wind power.

Refer to slide 8

Complete the missing words: The S_________ produces the w_ and the wind causes w_.
Waves can be used to turn t_ directly and generate electricity.
Wave energy is r. No air pollution is produced such as sulphur dioxide or nitrogen oxides that cause acid rain. It is also cheap to run once built. The problems are that it is expensive to set up. There are few areas suitable, it can kill flora and fauna and the energy you get is very l___ power.

Refer to slide 9

Complete the missing words:

The M_ causes the t. This causes the level of the sea to rise and fall.
This movement of the sea can be used to turn turbines directly and generate e.
Tidal energy is r and non-polluting. It is cheap to run once built.
The problems are that it is e to set up. There are few areas suitable, it can kill
flora and fauna and the energy you get is very l___ power.

Refer to slide 10

Complete the missing words:

This is where you burn o_____matter, be it plant or animal.
The reason it is classed as r is that you can reproduce this matter relatively quickly. For example, you can just grow some more plants.
However you do require a l _ area of land.

Refer to slide 11

Explain how Geothermal energy is generated.

Refer to slide 11

Tabulate 3 advantages and 2 disadvantages of using Geothermal energy.

Refer to slide 12

Explain how Hydroelectricity is generated.

Refer to slide 13

Tabulate 5 advantages and 5 disadvantages of using Hydroelectricity.

Renewable energy resources are expensive. Explain why if we continue using fossil fuels the world will find itself in a great deal of trouble. Mention the type of trouble.
