Solar energy
Introduction
Everyone on earth is familiar with solar power; it is the energy that the sun gives to the earth and is used by various organisms in various ways. Plants use solar energy to make food; cold-blooded animals use it to get their body temperature high enough to function while warm blooded animals use it for warmth. In the history of mankind, solar power has been critical. However, it is only in later years that the human race has acquired the technology necessary for collecting and storing solar energy. Solar panels and their attendant hardware make it possible to harness the energy, store it and transport it. The equipment has now become so small in some cases that one can wear it on his or her person. The paper shows

Wilhelm Hallwachs discovered that combining copper and cuprous oxide produced a photosensitive material in 1904. In the next year, Albert Einstein completed his work on the photoelectric effect and presented his paper on it. However, it was William G. Bailley of Carnegie Steel who created the present basic design of the solar panel consisting of copper coils and an insulated box. The period after the Second World War saw increased demand for solar power as energy needs went up and supplies could not keep up. There was an explosion of passive solar buildings in the country and that spurred more investments into the solar industry. It was at Bell Labs that the silicon photovoltaic cell was developed by Daryl Chapin, Calvin Fuller, and Gerald Pearson. It was the first cell that stored enough energy to run contemporary electric …show more content…
There are companies that are crafting photovoltaic material into jackets, trousers, watches, caps and more. When one wears the attire, he or she is instantly transformed into a walking power source. The attire collects and stores energy and then avails it to the wearer or anyone else the wearer might want to share with. It is an incredible advancement that has implications beyond the charging of mobile devices. Potentially, every human can add his or her energy to the grid. It is an advancement that goes one more step towards making every human responsible for his or her energy collection. With the technology getting better and better, the potential is truly
Instead, most of his inventions were made using electrical energy. In 1878 he dedicated almost two and half years of his life to invent incandescent electric lighting. He was granted a patent for the famous light bulb in 1880. That same year he founded the Edison Illuminating Company and then left Menlo Park to travel around the globe. He visited different cities, offering his consultation services to local union councils and electrical companies on how to implement electrical systems.
Thin solid films were probably first obtained in 1838 by electrolysis. They were systematically prepared by Faraday in 1857.
The Solyndra Company, founded in 2005 by Christian Gronet, designed, manufactured, and sold a unique type of solar panels. They were termed “solar photovoltaic (PV) systems” and were designed for large, flat to low sloped commercial building roofs. The panels were designed to have the best performance when mounted horizontally and to be installed very close together so that they covered a much higher percentage of the roof top thus producing more electricity than the typical flat panel solar panels by comparison. This was created through the production by absorbing light from all directions including indirect and reflected light as well as direct sunlight when combined with a white roof. This was due to the design of having rolled its copper indium gallium selenite or CIGS into a cylindrical shape. Each tube had 40 of them in each 1-meter-by-2-meter panel (Solyndra, 2008).
They renamed that department to Turbomach Division in 1980. Soon after, Solar Turbines became owned by Caterpillar
Based on Laurel Nesbit, a program assistant in the Office of Sustainability here at UF, our campus manages to utilize 470,000 Megawatts of energy annually. This figure is generated from all the energy-consuming gadgets that operate on our campus on a daily bases. These gadgets include computers that are left turned on over the night even they are not in use, copiers, and the fume hoods in our laboratories. Admittedly, the success and the health of wellbeing of the students is contingent upon some of these equipment. For instance, the laboratories need the fume hoods in order to keep the experimenters safe. Instead of casting these necessities away, we can develop alternatives which will be capable of generating energy in order to compensate for the electricity that we endlessly
Preview: Today I will discuss the potential that solar power has to become this country’s main supply of energy and the latest research that can make solar power more efficient and cost effective. I will also present the environmental benefits that come with using solar power over other and more harmful forms of energy.
Everyone is looking for a better way to have power. Solar power has very dependable technology, with little to no maintenance. It can bring finical savings by making more power a home owner may need and you can resell back the power company. Lastly help the environment by having no waste so less pollution and takes up unused space by putting them on to the roofs of the houses. In the end Home owners should try looking pass the initial price of Solar panels and see that this is a great way to produce energy that does not produce any carbon foot print.
The topic of my personal project was the usefulness of solar energy over the period of humankind. I touched upon the basic uses of the Sun for our environment, and also the ways that us humans have been manipulating the Sun’s energy for reasons of luxury and survival. More specifically, how humans have taking advantage of and the Sun for heating, survival, and electrical use over the history of humankind.
The sun has been a major aspect of life since the beginning of time. People used many other forms of energy before electricity was discovered. There has been a debate over energy resources for years. Many people are worried about what current energy resources may be doing to the environment. Oil spills and nuclear power plant mishaps have only been a few accidents that have had a big impact on the environment and the people who inhabit it. There are plenty of energy sources that do not harm the environment and are still able to get the job done. Solar energy is one energy alternative that will insure the betterment of the country and, at the same time, protect the natural environment.
When picking an energy resource for the topic of this paper, I bounced around a lot of ideas. Then it occurred to me that I should write about what I will be living with in about a month. My mom just finished designing and building our earthbag, solar, off-grid house, a four-year endeavor. I will soon live in a place powered by one of the most common alternative energy resources, solar energy, so I should learn more about it. At our new house, we have two stand alone pedestals with six 170W panels on each pedestal, making for a 2040W or 2kW solar system.
Whether you like it or not, the use of energy impacts all of us, either negatively or positively. It can affect our everyday lives by being anything from high gas prices, an overly expensive electric bill, and can also result in a plethora of greenhouse gas emissions. The Federal government is currently working with manufacturers and technology companies to improve the Modernized Grid that connects with the nation’s electricity. Improving the “Smart Grid” would allow us to produce electricity from more reusable and renewable sources. As a nation, we’re a little behind when it comes to things like this which also another result in America ranking out of the top ten in most energy efficient
The existing system has several disadvantages like solar energy and piezoelectric energy that are being in the system as an energy source can supply the load only for a particular period of time. A major drawback of the existing system is the charging of energy from the solar and piezoelectric is not always available. II. LITERATURE SURVEY This new generation needs lots of electrical power for their different multiple operations. Due to this many sources are wasted and exhausted in a large amount. There are various ways to generate electricity. The human waste foot energy is being use to produce electricity this would be a great evolution in electricity generation. The average human can take 3,000 - 5,000 steps a day. Similarly, solar energy is present throughout the day but the solar irradiation levels vary due to sun intensity and unpredictable shadows cast by clouds, birds, trees, etc. The common inherent drawback of vibration and photovoltaic systems are their intermittent natures that make them unreliable Solar energy is the viable source of renewable energy over the last two-three
Despite the importance that electricity plays in modern day society, many overlook where these advancements came from and where they started. In the 1800’s, when the population relied on hazardous candlesticks and lanterns for light, Thomas Edison explored something beyond him… the first electrical light source. The Electricity discovery resulted in many failures, but there were many contributors that improved upon the downfalls, making electricity a ongoing exploration.
I am certain that all have heard of the terms greenhouse 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).
The photovoltaic effect, electricity can be created directly from sunlight. Some semi-conductor materials that are exposed to sunlight can create electron-hole pairs, which can be collected to produce electricity. This occurs when photons have energy above a certain threshold. These photons have shorter wavelengths. In silicon, the threshold for electron-hole production is in the infrared region of the electromagnetic spectrum.
