Solar power

by Jaime Shadbolt

Electricity or  power these day can come from almost anything it can come from the sun ,water ,your old waste,wind basically anything .We are living in a new era of society where something great can come from something not so great. Our teacher has given us the project to make a presentation on one type of power so I choose the power that is right above our heads (most of the time) , I choose solar power (the sun) . I choose solar power because I thought it was cool how we convert the suns rays into electrics for our house or something.

How it works

Solar power works when the suns  rays shine down on to a special type of metal the rays turn to heat and it creates an electrical current which we can which we can then harness its power and use for our every day electrical needs.


It is free

It doesn't cause pollution

Solar energy can be used in remote areas where it is too expensive to extend the electricity power grid

Many everyday items such as calculators and other low power consuming devices can be powered by solar energy effectively.

It is estimated that the worlds oil reserves will last for 30 to 40 years.But solar energy is around forever


Solar energy can only be harnessed when it is daytime and sunny.

Solar collectors, panels and cells are relatively expensive to manufacture although prices are falling rapidly.

Solar power stations can be built but they do not match the power output of similar sized conventional power stations. They are also very expensive.

In countries such as the UK, the unreliable climate means that solar energy is also unreliable as a source of energy. Cloudy skies reduce its effectiveness.

Large areas of land are required to capture the suns energy. Collectors are usually arranged together especially when electricity is to be produced and used in the same location.

Solar power is used to charge batteries so that solar powered devices can be used at night. However, the batteries are large and heavy and need storage space. They also need replacing from time to time.

How will solar power help the future

Solar power will help the future because unlike other types of energies solar energy doesn't release carbon dioxide in to the air which is one of the main causes of global warming .And the fact that there is plenty of it  and its  free and does not belong to anybody makes it one of the most important of the non-conventional sources of energy .


I think that solar power is a great and healthy way to get your  power which can benefit you and the environment and will save you a lot of money .Solar powers a great way to gt electricyity and It does not release carbon dioxide in to the air which is one of the main cause of global warming.

Thanks for watching I hope you learnt heaps
