WHAT ABOUT FOSSIL FUELS?
        Fossil fuels are coal, fuel oil or natural gas, formed from the 
        remains of dead plants and animals. They are not renewable.
          At the moment we are still too reliant on fossil fuels. 
          Burning Fossil fuels is a big contributor to pollution.

          What is Solar Energy? Solar energy is when we use the sun’s light to create 
                                electricity.
        It is a renewable energy source that does not run out and does not pollute the 
                                  earth. 
                       WHEN WAS IT MADE AND HOW 
                                         DOES IT WORK? 
                In 1839 a French physicist named Edmond Becquerel was 
                experimenting with a cell of metal electrodes. He noticed the cell 
                produced more electricity when exposed to light. 
                This discovery helped Russell Ohl to create the first silicon solar cell in 
                1941.
                Sunlight is energy from the sun. The solar cell converts radiation 
                energy into electrical energy that we can use at home, at work and at 
                school.

              WHAT IS HYDRO ENERGY? 
           Hydro energy is when we use dams, the tides and the waves 
                     the create electricity.  
           Hydro energy is also one of the oldest power sources on the 
           planet.  It was used by farmers as far back as ancient Greece 
                for mechanical tasks like grinding grain. 
      HOW DO WE USE HYDRO ENERGY? 
      Hydro energy works like this: a pipe brings water to 
      a water wheel. The water from the pipe then 
      pushes the wheel which spins a generator that 
      generates electricity. 
      Hydropower costs less than most power sources 
      right now.
      Niagara Falls was the site of the USA’s first 
      hydroelectric generating facility, built in 
      1881, Charles Brush connected a generator to 
      turbines powered by the falls and used the 
      electricity to power night time lighting for 
      visiting tourists.
