   alternative energy is from the sun air or water this is use instead of electricity even though by doing something with alternative energy you can create (generate) energy.

   in my class some classmate already do theirs.
   here is the ides i most like. (only one i put attention)

   a oven that works with sun.
   you use some carton and cover it with aluminium and other stuff but i dont remember.

   i know is in spanish but just look the pictures so you get the idea.

   theres was one of my classmates who make i light bulb shine but i dont remember how he did it, the thing i do remember is that it shines when the wind blow.

   Alternative energy is about renewable energy. Energy sources such as solar thermal, wind, geothermal, tidal, and hydro-electric can be reused. Once set up there is lower running costs. Most of these sources are converted to electricity for distribution and use. These systems convert mechanical energy into electrical energy.

   Compare this with raw materials costs like, coal, gas and nuclear including above average inflation prices increases.

   Alternative energy is derived from natural, renewable resources such as wind, sun, and water. Renewable energy means that its use does not permanently deplete its existence. Renewable energy sources like biomass, small hydro, solar & wind allow you a broader freedom of operation.

   Wind power is generate by wind turbines or windmills. Solar power can be used to generate your business electricity.Electricity is generated from the sun’s rays that fall on the earth’s surface.
   The amount of energy the sun can release to earth in one hour is equal to the power consumption that the earth uses in an entire year.

   Alternative Energy is the way of our future.
