How Solar Power Has Many Different Applications For All Nations Around The World Essay

Climate change has been a major global issue for the past years and the use of non-renewable energy sources is only adding to the pollution that is responsible for the destruction of our planet. One of the biggest indicators of unproductivity is the lack of utilization of renewable energy sources. Currently, only a small percentage of Florida’s energy is attained by renewable sources (U.S. Energy Information Administration, 2017). The state of Florida is capable of at least partly running on solar or hydro power, but most schools don’t take advantage of the resources that are naturally occurring. Specifically, the School District of Palm Beach County operates a total of 112 schools, as reported by the school district website. Of them, ten have achieved LEED certification, a rating system that certifies “green schools,” meaning that they are energy efficient and use sustainable resources. This leaves the other 102 schools to continue to use up non-renewable resources and contribute to the mass pollution of the Earth. According to XCel Energy, schools spend billions of dollars yearly, just to deal with the daily expenses. However, a significant portion of a school budget is used for utilities such as air conditioning, water, and electricity. Both individual schools and the school district could save money by taking advantage of the natural resources in Palm Beach County. If schools were to incorporate more renewable

     In 1954 Bell Laboratories invented the first photovoltaic (or solar) cell, made from the semi-conductor silicon, and other elements. It was the first way to convert sunlight directly into electricity. When the space program was launched in the 60's, it

Solar Power has been observed as early as the year of 1839 by a French physicist named Alexandre-Edmond Becquerel. He invented the first photovoltaic cell. Since then his studies and works have been perfected on and continue to change the world in which we live for the better. Photovoltaic cells have constantly been evolving ever since. In 1883, Charles Fritts built the first solid state photovoltaic cell using materials such as gold and selenium. With further advances to the system, scientist were able to recreate the cell in a way that could serve as an alternative power source on the satellite named Vanguard that was flown into space in the year of 1958. In the 1970’s there was an oil crisis when Middle Eastern countries proclaimed a trading ban, encouraging oil companies to buy solar firms. Funded research allowed for first, second and third generation cells to be constructed. Currently, the cost of solar energy has exponentially decreased with the falling price of silicon, allowing for many new innovations to take place.

The greatest energy that can be produced by the sun is electricity. Photovoltaics, or solar cells, capture the sun and convert it into electricity. Solar cells were discovered by the Europeans back in the 1870’s when they used selenium to develop the telegraph. They found that when light hits selenium it would produce and electrical current. Soon enough there were many scientists and engineers working on photovoltaic systems. Silicon and Selenium proved to be the two best elements to conduct electricity when light hits them. Photovoltaic systems (PV cell) work by converting the suns light into electricity. A semi conducting material absorbs the sunlight, that energy knocks electrons loose from their atoms, this allows the electrons to flow through the material to produce electricity. The further development of solar cells can be attributed to the satellite industry. Solar cells were expensive and there was no use for them until satellites came. Because it is impractical to tether satellites it became important to develop solar energy at any cost that would power these satellites. This created a sustainable market for solar power, the first of its kind.

Imagine a world without light, a world filled with so much darkness that it would be nearly impossible to see anything, to use anything or to even function. A world without light would be a world without energy, without being able to use our phones 24/7, a world without all the comforts, mainly a world with hardships and struggles. We live in a world where energy is needed for everything. Nothing really works without electricity. For example, Energy is constantly being used to charge cellular devices, warm food in the microwave or even to charge electrical cars. The world is shifting it went from the extracting of unnatural fossil fuels to the discovery of a more natural way call solar energy. In order to know how crucial solar energy is it

I am certain that all have heard of the terms green house gases, fossil fuels, and global warming. Have you ever questioned what will happen if nothing is done about the environmental problems facing the world today? What if I answer you that, we can merely use the power from the sun to power up our entire planet without the use of harmful energy sources, which affect our atmosphere? The power from the sun is what we call solar power. Solar power is the energy that comes from the sun as light and heat energy, and then it is later converted into electrical energy through solar panels (Nelson, 2008). This kind of power is completely free, right? Why should we put a lot of expense on other sources of energy, when there is a complete free

In order for one to further understand the importance of solar energy, the problem of global warming must be explained. As defined by Webster’s Dictionary, “Global Warming” is an increase in the earth’s average atmospheric temperature that causes corresponding changes in climate and that may result from the greenhouse effect. With an average increase in atmospheric temperatures, our planet is slowly deteriorating. In order to stall or halt this global destruction, countries must turn to solar energy as a cleaner alternative to the depletion of fossil fuels. Solar energy creates a homeostasis for the climate. Due to its ability to decrease global climate changes, solar power can address global warming in several ways.

The question is, “why utilize the solar energy for our homes that is given from an existing power source for free?” A simple answer could be because the source of power in the long run is for free. The truth to the statement is nothing is for free because taking advantage of the sun does require some effort, but there certainly isn’t as much effort compared to the energy sources that we use today. More importantly there aren’t any severe consequences left for the environment during the process. The more learning and the more realization of how fast the quality of life is depreciating environmentally conscious citizens look to others observing ignorance for failing to come to the same standards of view. Utilization

Solar energy and its use isn’t new to the world. It has been used by various societies beginning from 7thCentury B.C, when the sun’s heat was concentrated by glass and mirrors to light fires. Today, we have everything from solar-powered buildings to solar-powered vehicles. By and large solar technology has some environmental, economic, psychological and ethical implications for our society. Actions taken by companies and individuals to increase the use of solar technology will create good local jobs, improve our environment and reduce our dependence on foreign oil while doing what’s ethical and moral for our society.

I went to go see Catching the Sun and it honestly was one of the most fascinating, interesting things I have ever seen. It was very eye opening and informational. Catching the sun was mainly about making a more greener world with solar energy. In the beginning of the film it was an explosion at the Chevy refinery in Richmond, CA. A lot of people were upset because of the effects it had on the community. It took us through different people lives with their contribute with solar. Rather they were a solar trainee, an entrepreneur or a businessman. The film showed us the advantages of solar energy. It did not just show us things going on in the States, but also around the world in different countries. It was a really intriguing film. At the end of it we had a small discussion about the film and questions were asked. In order for any change to happen, it has to start with the people in community first.

The term ‘photo’ means light and ‘voltaic mean electricity. A photovoltaic (PV) cell is also known as solar cell. Even though, photovoltaic effect was observed in 1839 by the French scientist Edmund Becquerel, it was not fully comprehensible until the development of quantum theory of light and solid state physics in early to middle 1900s. Since its first commercial use in powering orbital satellites of the US space programs in the 1950s. While most PV cells in use today are silicon-based, cells made of other semiconductor materials are expected to surpass silicon PV cells in performance and cost and become viable competitors in the PV marketplace

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

Solar associated energy may be turning into an engaging elective for powering self-sufficient wireless frameworks. This communication framework is more prominent in rural areas for security as a source of safety. Their design configurations frequently include the utilization of efficient antennas and individual photovoltaics. Some photovoltaic technologies are available, but are not limited to emitter wrap-through (EWT) rear-contact solar cells, amorphous silicon (a-Si) thin film on the glass substrate, polycrystalline silicon (poly-Si) and bifacial solar cells. However, limited accessible space for these configurations is a limiting factor.

The Sun is a leading environmentally clean energy source. The process of generating electricity from sunlight has been known for over a hundred years. Edmond Becquerel first observed the photovoltaic effect in 1839 (Zamostny, p. 1). Through a series of experiments on electricity, he plunged two metal electrodes in a conductive solution and exposed it to sunlight. As a result, there was a small electrical voltage between electrodes.

Large solar plants occupy a vast area of land and threaten wildlife because one square kilometer is needed to produce 40 megawatts of energy from solar power.4 British scientists are attempting to improve the effectiveness of photovoltaic cells by utilizing “copper indium diselenide and cadmium telluride to find an affordable and more sustainable way to make solar panels to convert light energy into electricity.”5
