With the advent of technology, people have discovered ways to harvest electricity from the sun’s light. The sun’s light has energy and usually when it hits a surface, the energy turns into heat. For example when you turn your face to the sunlight, the warmth that you feel on your skin is actually the result of the energy in the sun’s light turning into heat as the light touches your face. When the sunlight hits specific materials like silicon, the energy will turn into an electrical current instead of heat. This electrical current is what is harvest. Though solar energy accounts for a tiny portion of the total electricity generated in the U.S, right now scientists are looking to develop cheaper materials that can be massed produced so that fossil fuels can eventually be replaced with solar energy in producing electricity.
