1/ what is the essential difference between alternative energies (AE) and fossil fuels? Alternative energies will not have a lot of pollution, but fossil fuels will cause some pollution of the environment. Some fossil fuels causes environmental pollution, for example, global climate change, a lot of carbon dioxide cause the greenhouse effect, acid rain emissions of harmful gases cause serious pollution to the atmosphere.

2/ name the AE that you have chosen to research.
Solar Energy

3/ identify the – source or origin of this energy;
According to records, human use of solar energy has 3,000 years of history. Solar power as an energy source and make use of only 300 years of history. Real solar as "the recent much-needed additional energy," "the basis for the future energy mix," is a recent thing. Since the 70s of the 20th century, solar energy technology advances, solar energy with each passing day. The history of modern solar energy engineer from France Solomon and Germany 1615 Cox invented the world's first solar-powered engines counting. The invention is a use of solar energy for heating the air to expand power and water pumping machines. In the years between 1615 to 1900, the world has developed into more than one solar power plant and some other solar devices. Almost all of these power plants collect the sun by concentrating mode, engine power is not, working fluid is mainly water vapor, expensive, little practical value, the majority of personal research and manufacturing of solar enthusiasts. 100 years of the 20th century, the history of solar energy technology can be generally divided into seven phases, the following description separately. Location(s) of this energy source.

 United States
4/ explain how the energy is obtained/extracted/produced. (Labelled diagrams will be quite useful in your answer). Collected by solar panels and convert the chemical energy stored in the battery, and then you can use it...
