A.Benefits Of Solar Energy
Does not release green house gases
Production of solar energy does not produce smoke, gas, or any other chemical byproducts •Solar energy contributes to about 4 percent of the world’s electricity •Italy’s Montalto di Castro solar park:

ogood example of how solar contributes to the decrease in emissions oDecreases the carbon emissions by about 20,000 tons per year compared to fossil fuel energy production. •Money!
oExcept for the initial installation and maintenance, solar energy is absolutely free oDoes not require expensive raw materials like oil or coal oLess staff working at the power plants since the sun and solar semi conductors do majority of the work •Jobs

oCreates jobs
oAccording to the EIAA, Europe’s solar industry created 100,000 jobs oTypes of jobs include: manufacturing, installing, monitoring and maintaining solar panels, research and design. Development, cultural integration, and policy jobs •Benefits the eco system

oWill not require the destruction of forests because solar energy does not require constantly mining raw materials •Water
According to the American Wind Energy Association:
oNuclear power: 2.3 liters of water required to produce one kilowatt hour of electricity oCoal: 1.9 liters of water required to produce one kilowatt hour of electricity oOil: 1.6 liters of water required to produce one kilowatt hour of electricity oSolar Energy: 110 milliliters of water required to produce one kilowatt hour of electricity oHence solar energy does not use as much water

B.How solar energy is produced
Solar panels work through photovoltaic process
oRadiation energy is absorbed and it generates electricity
Specifically, radiation energy is absorbed through semi conductor cells, which are normally silicon. Then it is transformed from light energy into electric current •When the radiation of the sun hits a silicon atom, a photon of light energy is absorbed •This...
