(Intro) Solar Energy is an underrated renewable energy source. We should be looking to make advances to become more dependent on renewable energy sources such as solar energy. The more we rely on these new energy sources the more carbon dioxide, sulfur dioxide, and other greenhouse gases we could eliminate from the air which will help ensure a clean and safe environment for future generations. In addition, it could aid America to depend less on other countries for energy sources such as coal, petroleum, fossil fuels, and oil. Renewable energy sources could result in riding the countries worry of running out of natural energy sources. It can dramatically reduce your electricity bills, add value to your home, and potentially make you money. However, renewable energy lags far behind natural resources we should advocate and invest in advancing the technology and uses of solar energy.
(Background) Solar cells came about in 1883 designed by Charles Fritts. Solar did not come to America until later in the 1950s but was only used by NASA or for space applications. Introduced to the public in 1970 and was used to power navigation warning lights and horns on many offshore gas and oilrigs, lighthouses, railroad crossings. Domestic solar applications were viewed, as practical applications in remote locations where grid connected utilities could not exist affordably.
(How solar works) Photovoltaic cells absorb energy from sunlight. Once the light hits the panels it heats them and turns it into a direct electrical current. This electricity is fed through an inverter to become alternating current (AC), the same form of electricity that is used in homes and businesses and serves some portion of the home or business’ electricity needs. Although it is similar to what plants do; they absorb the sun’s rays and convert it to energy. Solar concentrating towers use mirrors to concentrate the solar rays to specific
