= Alternative Energy =

The kinds of energy we are using now are harmful to our enviornment. Such as burning coal. We are not going to have it forever, it will eventually run out.Also its bad for the earth because its creating harmful toxins which is hitting our atomosphere.Alternative energy is the way to go and here are some of those other alternative energys we can use.

Solar Power Energy Solar power energy is energy from the sun. Solar panels are used to collect heat from the suns rays.

Then that heat is sent to pipes in the solar panels then water is heated when it passes through the pipes. That is one way how solar energy is used. Its also cleaner than coal or gas because it doesent give off any bad toxins and it wont ever run out because the sun is always shining. Now here is a picture to kinda show you how this works. T here are two diffent kinds of panels Solar panels and PV panels. THe dofference is that solar panels are for heating water and PV panels creates electrisity. [|Solar energy] [|Solar Energy 2]

Wind Power Wind energy is poweres by wind (obviously). It is generated in wind turbines where the energy in the wind is harvested into these wind turbines.Wind turbines are connected to an electric generator which creates a electric current which can be used for a home. the bad thing about wind power is that it is so expensive for a turbine. Here are a couple of pictures of what turbines are and how they work.
