This is a presentation form my sister about energy

2.  The main source of energy comes from the sun but some
others are manufactured. Energy is basically the source of
life everything we do is made from energy.
 There is a wild variety of different types of energy that we
use and the three main ones are coal, gas and oil. These
are vey useful because oil is use to make petrol, cooking,
painting and heating and lots more.
 Gas is used for heating and cooking and hot water and so
many more things.
 Coal is used for fire and lots more so that's why energy is
so important or without is it would be very hard to live.

3.  Renewable energy is when the energy is found from natural
recourses and as we use it, it is being restored at the same
time so it will never run out. The three types of energy
that I am going to be writing about are Solar power, Wind
farms and Wave power.

4.  Non-renewable energy is the opposite of renewable energy
it has all processed and we (the world) are using it too fast
for more to process in time so that’s why is non-
renewable.

5.  Solar power is a type of energy that people use it can do many things.
 It is basically energy transmitted from the sun that people use in their
homes.
 Here is a diagram to show you how it is made:
 Here are the advantages of having solar power:
 It is completely renewable
 It does not make any noise
 No pollution at all
 They last quite long
 Now the disadvantages
 They are expensive
 The weather might not be great
 Need quite a few
 Only works in day time

6.  Wind farms are basically a lot of wind turbines. The wind
turbines power electricity so people can use them in their
homes.
 They are used for a lot of things.
 Here are the advantages of having them:
 Low pollution
 No land lost
 Low cost energy
 Here are the disadvantages
 Reliant on wind
 They are noisy
 You would need lots.
 They are big very big.

7.  The next electricity I want to talk about is wave power and
its powered by waves this time.
 It can be used for many thing even the things you wouldn’t
think about.
 Here are the advantages of wave power:
 Low pollution
 Lower flooding risk
 Low running cost
 Now to bad ones, the disadvantages
 Pricey to build
 Damage to landscape
 Methane and CO2

8.  I think that the solar power is the most sufficient energy
because it is from the sun and it can never run out and if it
does there is a back-up stock so it’s quite good.
 Even though you would need a lot of them it is free.
 It does not cause pollution or anything like that.
 It is totally renewable.
 Thank you for reading this PowerPoint.
