Solar Energy

1.     What Solar Energy is used for

     How Solar Energy was used  has improved.  Over the years things have changed: In the past people have designed houses to attract heat in the winter.  In the present,  people now use electricity to heat the house.  Maybe in the future we will have self powered heaters.

2.     How the sun makes energy

     The sun always had energy and heat.  How the solar panel makes energy is by the sun’s solar cell: the solar cell goes to the solar panel.  It breaks up and makes energy.  The energy renews the electricity, makes the electricity positive, and it will come back negative. The photovoltaic effect happens again.

3.     Photovoltaic Effect

    The Photovoltaic Effect is an effect and a current used as a piece of material is used to make the electricity.  People use the electricity to power useful things that help a lot.  Some people feel grateful to have electricity but some people want to use things differently.  But life in some places is a little different and some places are a lot different.

4.     How Wind makes electricity

    Wind is only some piece of air that is moving.  The wind-turbine makes the electricity by the wind.  The wind turns the wind-turbine then the turning makes a piece of metal turn which then makes a spark.  The spark makes the electricity which then is used for things to be powered. The wind turbine can be only powered by the metal turning because then it won’t make even a spark if it isn’t turning.

5.     Cool Idea

      Do you want to save energy?  Well, if you want to then take solar panels to be able to get electricity by the sunshine and probably when it rains.  You can get a battery for the night, or you can go to bed early to be able to sleep before the night.  You can use a heater to make snow go away or else you won’t have electricity.  Take a wind-turbine for windy days. So, that’s how you can save electricity or you can try to make a different idea to save electricity.  Have fun!
