2. WHY SOLAR ENERGY?
•
We chose Solar energy because it seemed interesting and we wanted to do more research
explaining how solar energy is formed and brainstorming ideas to keeping our planet clean.
WHAT TYPE OF ENERGY IS IT?
•
Solar energy is a renewable energy, it uses energy and light to provide heat, light, hot water,
electricity and cooling for homes.
HOW WE USE SOLAR ENERGY
The suns light contain energy. When light makes contact with an object the energy turns into heat,
but when light hits certain materials the energy turns into electrical current instead.

3. WHERE DOES SOLAR ENERGY COME FROM?
•
Solar energy comes from the lowest point of the sun. The sun is a hot ball of hydrogen and
helium. Due to fission reaction of hydrogen molecules, energy is emitted which is known as
solar energy. The sun bears a constant stream of thermonuclear explosions as hydrogen
atoms are merged into helium atoms. The sun is like a humongous power station that
constantly does a reaction that lets out light.
•
Solar energy is possible anywhere on earth where the sun shines. It is usually used in homes
as a source of electricity.

4. SOLAR ENERGY
•
Disadvantages
•
Advantages
•
Solar energy is only available when the
sun is shining.
•
Solar cells are long lasting sources of
energy which can be anywhere
•
Its low efficiency, requiring large areas
of land
•
•
Its not completely free of environmental
impact
Solar cells provide solutions to energy
problems in places where there is no
main electricity
•
Solar cells are silent and non-polluting
•
They have a long life time and could be
installed on roofs which means no new
space is needed.
•
Some people have solar panels on their
roof & they’re responsible for cleaning it
once a year.
