This paper will explore the many aspects of solar energy. From how it was discovered to what it is used for, how it is used, and the many benefits of it. Solar energy is defined as, radiant energy emitted by the sun. Solar energy has been used for many years and also has been used to generate a number of things that we use today, from solar powered cars and cell phones; solar energy is a huge aspect of human life as we know it. If it weren’t for solar energy, many things may not be able to operate and many other things may not have been discovered because of it.
Solar energy has a long history, dating back to 1767. A Swiss scientist by the name of Horace-Benedict de Saussure created an insulated box with three layers of glass, absorbing energy …show more content…

It can be used for ventilation, heating swimming pools, heating a home and even indoor and outdoor lighting. Who would have thought that solar energy would become a part of everyday life? Solar energy can be used residentially, commercially and for transportation. Residential use is of course for a home by powering lights, appliances and other electrical devices; the most common and least expensive for residential use is a grid-tied PV system. The PV system allows homeowners to use their own solar-generated energy and also save money while doing it. The grid-tied system comes with many benefits, excess electricity being produced can be fed back to the grid through a process known as net-metering. Many homeowners seem to be converting to a solar powered home to ultimately reduce the cost of electricity. Commercial use is also an aspect of society that uses solar energy to reduce the cost of electricity. Commercial and residential solar energy use seems to go hand and hand; if a company invests in solar panels, it would benefit and help the company in so many ways. Companies that use solar power benefit from incentives controlled by the government, such as the Feed-In Tariff scheme. Depending on the amount of energy their solar panel system produces, the business makes money. There are number of business that make money yearly because of this incentive; this …show more content…

In 2011 a team of researchers led by Jan Kleissl, a professor of environmental engineering at the UC San Diego Jacobs School of Engineering, discovered that solar panels on top of a building or home, cools the place five degrees cooler than when it was under an uncovered roof. They also discovered that at night the panels trapped the heat in, reducing the heating cost in the winter; the panels act as shade on the roof. “The more efficient the solar panels, the bigger the cooling effect…the panels reduced the amount of heat reaching the roof by about 38 percent” (NSF). Solar power is ongoing free energy; it doesn’t require raw materials to operate because it comes from a natural source, the sun. Solar power plants also benefit the society by producing jobs. In an article written by David Anderson, he stated that “in 2007 the solar power industry accounted for the majority of the 89,000 jobs creating, distributing and storing clean, renewable energy found in the United States” (Anderson). During this time 65 percent of energy generated jobs were solar based. As far as job creation, solar is ahead of coal by a long shot. Because solar energy is so inexpensive to access, “solar panels have seen a consistent drop in prices over the last three decades and in the last few years; prices have gone from $77/watt to around $.75/watt. That makes solar 99 percent cheaper than it used to be. Since 2008, the cost of coal has
