Solar PowerIntroductionSolar power is one of the cleanest forms of energy available today. Switching current house and new builds energy sources to solarpowered would have a positive effect on our environment. However, it can be costly to install or convert and hard to find banks that finance homes that only source of power is solar. Throughout this paper I will touch on the historical and contemporary viewpoints of solar power, how it can be applied in our lives as well as globally.History and Contemporary Viewpoint: 100+ years agoHumans harnessing the suns power began thousands of years ago. Neanderthals discovered how to use sunlight and glass to start fires in 700 B.C. According to Greek mythology, around 212 BC, Archimedes used a “heat ray” to destroy enemy ships. The fiery destruction was supposedly caused from a mass amount of mirrors angling the suns rays directly at the opposing ships. While scientist have never been able recreate the event, it has been deemed possible,although unlikely. The Neanderthals were dependent on fire for warmth and cooked food. By 1767 Neanderthals had evolved into Homo sapiens and the use of solar power to cook food had evolved with him. The first solar oven was invented and used by Swiss scientists Horace-Benedict de Saussure. The oven was created with an insulated box that was 2

Solar ovens are still used today, especially in villages where electricity is not easily accessible. After the invention of the solar oven, solar power discoveries and inventions began growing rapidly. In the 1800’s the Photovoltaic Effect and photoconductivity were discovered. These discoveries proved that materials exposed to the suns light created voltages (photoelectric effect) and laid the groundwork for the first solar cell plans. Famous scientist, Albert Einstein published a paper in 1905 explaining how the photoelectric effect works. History and Contemporary Viewpoint: Within the last 100 yearsBy the 1950’s solar cells were available for purchase commercially. The U.S and Soviet Union began using solar cells to power satellites orbiting the earth. The National Historic Registry building was the first to have solar powered hot water. In the 1960’s France was the first country to invent the solar powered furnace. By the 1970’s the first solar powered house was built by Delaware University. Today, there are countless uses of solar cells; cars, aircrafts, houses, lights, etc… Many towns throughout the United States have 3
