Research Paper On Solar Energy

Solar energy is clean, eco-friendly and also sustainable. Due to the fact that the energy produced from the

     The real question around the beginning of the 19th century concerning solar energy was "could the sun produce electricity directly?" The main motivation behind this desire was that electricity could be stored in a battery, and used later. It would not be necessary to use the device in the sunlight. All inventions failed, until Frank Shuman, an engineer from Pennsylvania finally made a breakthrough. He built an experimental plant that used black troughs covered in glass with a few inches of water. When exposed to the sun, the water got very hot, causing it to circulate and power an electric generator. His data was so convincing that he got financial backers and built the world's first solar electric power plant in Egypt. However, the Eastern Sun Power Company went out of business even though it was using free fuel. It didn't produce enough electricity for the area that it used, 14,000 sq. ft of sun-collecting land (Zweibel 48).

The concept of solar energy is not a new one. We have seen it in practice from solar powered calculators, garden lights, watches, and a wide variety of other novelty products. However, the idea of solar energy as a sustainable, renewable form of electricity, is on another level completely. Solar energy is one of the most popular and fastest growing sources of alternative energy not only in the country, but in the world.

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.

According to solarhome, the term solar power more specifically refers to the use of the sun’s energy for electricity.

Solar energy is the energy that the sun shines onto Earth. There are two types of solar energy, photovoltaic and thermal (Beltran). Solar panels are used to acquire the sunlight which then the photovoltaic cells convert into electricity. Solar concentrators collects the sun’s heat to make solar thermal energy which is used for heating. Both are used for different purposes, but they all originate from the sun and are all solar energy.

A. Good things about Solar Energy. Nowadays, they think about the economics to how become it

To show solar to another green energy here is a compare and contrast of wind and solar. Wind power is more popular than solar in the USA and that is a fact, but wind powers turbines take up way more space than solar panels. If the area you are in is not windy the wind power

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.

Solar energy has been in existence for a longer than any of us will imagine. Of course the sun is the oldest and most basic source of energy. Solar technology has been in existence since the 7th century B.C. Solar energy is a clean and renewable energy that does not have most of the problems fossil fuels have. There are three types of solar technology that can be utilized in both our homes and businesses. The three types of solar energy are solar thermal and solar electric which can also be called photovoltaic (PV) and passive solar energy. Solar energy is developing and could be used as an alternative for fossil fuel which emits dangerous gasses into the atmosphere. I will be discussing about the benefits, problems and how solar energy can be improved in the United States.

Solar technology can be dated all the way from 7th century B.C. Early uses included using reflective properties to direct sunlight to create energy (heat) to a specific area. In 1838 French scientist Edmond Becquerel discovered the ‘photovoltaic effect’ which involved an electrolytic cell submerged in a solution, that when exposed to light, created energy. This discovery made way for Charles Fritts (1894) to create the first solar cell, which consists of a coating semiconductor material with a thin layer of gold. This first solar cell was only 1% efficient so energy production was not viable; put into perspective, today’s solar technology is 46% efficient.

Solar power has many different applications for all nations around the world. As you 've read before it can be used to create electricity for homes, businesses, etc. or in order to power different machines, facilities, and household items that we use every day. For our project we will be looking at using it in order to help the nation of Somalia, more specifically we will be looking at Mogadishu which is the capital of Somalia. The area is on the Horn of Africa and to the west of the Indian Ocean. The area is made of mostly plains and highlands giving it a lot of potential to create solar energy. In this area on average on a clear day it will produce about 7 Kilowatts of energy making it a very good place for solar panels to be able to create electricity to run things. Somali has recently come under much political unrest forcing a lot of people to flee from the country and a lot more to have to stay and suffer from it. By creating something that is regenerative and cannot be limited because of lack of resources in order for politicians to try to keep in charge it 's giving a needed break the Somalians who were unable to escape the country.

The Sun is one of the most significant sources of renewable energy. In one hour the Earth receives enough energy from the Sun to meet its needs for nearly a year. A Photovoltaic (PV)

As we all know, fossil fuel energy comes from wood and some organic materials from millions years ago. They experienced slow chemical process and became the coal and raw petroleum as we see today. However, since the first industry revolution, the speed of mining fossil materials and consuming all kinds of oil products has been accelerating in a geometric growth. People use coal to generated trains, and they use fuel to generated the majority of their engines, which includes cars, aircrafts, and heating machine. We have billions of people on earth right now, and everyone needs to consume energy for transportation, lightning and many fields in various ways. Where do the energy come from in the past three hundred years? Absolutely from the fossil material. But fossil energy is not unlimited, it has a maximum. When we consume it till the edge, then we have nothing to generate our machine. Luckily, solutions are always more than the problems. We create the way that is called renewable energy. It helps us retrieve energy from nature, like solar, wind, and water. These kinds of energy are unlimited, relatively, which means if the sun doesn’t fall down, the oceans aren’t dry, we can get power from them. However, even though it has a bright future, we still have many obstacles needed to be solved. (Hepbasli & Alsuhaibani 2011)

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.
