The earth has lots of energy sources such as nuclear energy, fossil energy, and renewable sources. Solar, wind, geothermal, and water are renewable sources of energy. These energy sources are clean. They do not produce any pollution. But the most reliable energy source is the sun. The sun is an important part of living things. It produces an energy called solar energy. Solar energy is the earth’s main source of energy which can be transformed into heat and electricity. Its energy was used to heat and to light homes during the earliest centuries. Without the sun, living things on earth would not surely survive because it would be extremely cold and dark. According to the article “Solar Energy,” every year the sun carries an average of 1.5 kilowatt-hours of energy to the earth in the form of visible light, X-ray, ultraviolet, and infrared radiation (Solar Energy). Solar energy can be converted into electricity in two ways. The first one is with the use of solar thermal or electric power plants that creates power by concentrating the sun’s energy to heat the liquid and produce steam which is used to power a generator. (Solar Explained). This is mostly similar to coal and nuclear power plant.
Another way is by using photovoltaic cells or solar cells that transform sunlight directly into electricity (Solar Explained). In May 1954, photovoltaic cell, which is made out of a semiconductor called silicon, was developed by three research scientists at Bell Telecommunication…
