2. Fossil Fuels are used in power plants to create energy for your home, or in certain vehicles to create motion, such as in a plane. These fuels are burned to create heat, which makes steam which turns a turbine, connected to a generator. The largest problems with fossil fuels are that they take millions of years to be made, release toxic gases, and the efficiency of the entire process is maybe 3%, meaning that three percent of the energy in the fossil fuels are converted to electricity. A large amount of the heat made is lost, and other mechanical imperfections that add up. Solar panels create electricity directly through a process that is difficult to explain. In essence electricity is the movement of electrons, and solar power works on the hypothetical photon, a single packet of light energy. A solar panel has bare wires in layers of solid chemicals that shows out through a glass cover. Photons travel through the glass and knock electrons out of the wire into one below, and since an electron has to fill that missing electrons place, the electrons move, creating a current. Solar panels create electricity with a higher efficiency rate, using renewable resources, and without releasing toxins. It is estimated that if the whole earth were covered in solar panels, we would get as much electricity in a day, as would be needed to power the world for three years.

   Hope this helps!
