Development and Importance of Solar Electricity

Development and Importance of solar electrical clevernessNoxious gasses, corrosive fumes, scarred shootscapes, a massive ampere-second footprint, and a state of warming ambience. These atomic number 18 the consequences of obtaining zip fastener from nonrenewable resources such as coal, natural gas, and petroleum. These be the sources we occasion to coif go forth electricity, endangering the genuinely planet we live on through their hurtful impacts on the environment. These destructive effects include, but be not special(a) to, the creation of a blanket of carbon dioxide which traps heat in the atmosphere and thus warms it, water and ground contami domain from spills and other(a) mishaps, and air pollution. there is a give away answer to obtaining electricity, one which reduces greenhouse gas emissions and has a lots, very such(prenominal) sm wholeer impact on the environment the photovoltaic (PV) cell, withal known as the solar cell. Be causa the solar cell ha s these incredible benefits, our population should invest much more money into seek and buildment of solar power to generate electricity.Thanks to considerable public investment in green energy that came from the US, Germany, and China during the Great Recession, recent Ameri fecal matter and European regulations that chip in de-incentivized coal power plants , competition among renderrs, and technological know-how (R. Meyer How solar and horn in Got So Cheap, So Fast 1), solar energy has become much cheaper, and thus, economically viable. While follows do vary between regions and types of solar panels, the average cost is close to 60 cents per watt (R. Meyer How solar and repeal Got So Cheap, So Fast 1).solar cell technology has been around since 1839 when French physicist Alexandre Edmond Becquerellar basic demonstrated the photovoltaic effect, or the ability of a solar cell to convert sunlight into electricity (R. Meyer tarradiddle of solar male monarch 1). Forty-four years later, in 1883, the American inventor Charles Fritts created the terra firmas first rooftop solar array in New York (R. Meyer History of solar fountain 1). Up to this point, however, the process behind the photovoltaic effect (also known as the photoelectric effect) was not understood. The process continued to elude scientists until 1905 when Albert adept wrote a paper explaining the photoelectric effect (R. Meyer History of Solar top executive 1). Together, Becquerellar and Einstein paved the way for the development of photovoltaic technology. During the 1950s, the U.S. military funded research on PV technologys potential to power satellites (R. Meyer History of Solar advocator 1), and in 1964 the issue Aeronautics and Space Administration (NASA) launched its first satellite equipped with solar panels. However, it wasnt until the Arab oil embargo of 1973 and the ensuing energy crisis that the United States started to earnestly develop solar energy. The U.S. governments first step was passing the Solar Heating and chill Demonstration knead of 1974 (R. Meyer History of Solar Power 1), which created the Solar strength Coordination and Management Project, an organization designed to direct agencies like NASA, the National acquaintance Foundation, and the Department of Housing and Urban Development to improve solar energy technology (R. Meyer History of Solar Power 1). When Jimmy Carter became President in 1977, he labeled the energy crisis as the moral equivalent of war and made energy policy a top priority of his political science (R. Meyer History of Solar Power 2). That same year, he created the Department of get-up-and-go and pushed through copulation several acts relating to renewable energy use. The goal of Carters efforts and those of Congress was to make solar viable and affordable and market it to the public (R. Meyer History of Solar Power 2). In facilitating this goal, Congress created the commercial investment tax income credit (I TC) and the residential energy credit (or residential ITC) to provide financial incentives for the public to purchase solar properties (R. Meyer History of Solar Power 2). Unfortunately, the tax credit failed to increase Americas use of solar power, as solar comprised a negligible amount of electricity propagation (R. Meyer History of Solar Power 2). However, declining domestic oil work and rising oil imports throughout the wee 2000s (R. Meyer History of Solar Power 2) led to the Energy Policy Act of 2005 (EPAct). This act raised the commercial ITC to a temporary 30 percentage rate and reindeclared the residential ITC which had expired in 1985 (R. Meyer History of Solar Power 2). Today, in addition to tax credits and grants, the government continues to heavily subsidize the industry with research and development, commercialization, and regulatory support (R. Meyer History of Solar Power 3).In 1985, fundamental renewable energy production and consumption amounted to 6084 ca rdinal Btu. Out of that amount, less than half trillion Btu came from solar power, less than 0.0008 percent of total renewable energy. In comparison in 2015, total renewable energy production and consumption amounted to 9466 trillion Btu. Out of that amount, 427 trillion Btu came from solar power, about 4.5 percent of total renewable energy. This means from 1985 to 2015 total renewable energy production and consumption increased by 3382 trillion Btu, season in the same time period, solar energy consumption and production has increased by around. 426.5 trillion Btu (US EIA Monthly Energy Review January 2017 151). electricity is an extremely important factor of our everyday lives, but we should obtain this demand resource much more responsibly through solar power. Solar power discloses significantly less greenhouse gas emissions (more specifically carbon dioxide) and has a very high skilful potential.According to the United States environmental Protection Agency (EPA), greenhouse gases are gases that trap heat in the atmosphere (EPA 1). In 2014, 81% of all greenhouse gas emissions in the United States came from carbon dioxide, which amounted to 556,470,000 metric tons (EPA 1). This carbon dioxide enters the atmosphere through burning fossil fuels (such as coal, natural gas, and oil), as well as solid waste, trees and wood products, and also as a result of authentic chemical reactions (EPA 1). According to the EPA, 37% of carbon dioxide produced comes from generation of electricity (EPA 1). If our nation used solar power to generate electricity, the amount of carbon dioxide we produce would drastically decrease, as the carbon footprint of the solar industry is much, much smaller than that of the oil or gas business (R. Meyers The Solar perseverance Has Paid Off Its nose candy Debts 2). This is made possible because the energy put into making solar panels, such as quart and copper being mined. The black materials being converted into wafers, then being enc ased in protective material Has the solar industry really saved any energy at all? (R. Meyers The Solar industriousness Has Paid Off Its hundred Debts). Researchers at the University of Utrecht and the University of Groningen have determined that the answer is yes, using a type of research called lifecycle analysis, which investigates the total environmental impact of a product over time (R. Meyer The Solar sedulousness Has Paid Off Its Carbon Debts 2). According to Meyers, this kind of research is tricky researchers must find and calibrate years of economic and energy data, collected across 40 years, in many diametrical countries, with different goals in mind (R. Meyers The Solar Energy Has Paid Off Its Carbon Debts 2). Scott Hershey, a professor of chemical and environmental engineering at Olin College, stated in an email that their the researchers methods are solid, but this type of analysis is pregnant with assumptions (R. Meyer The Solar Energy Has Paid Off Its Carbon Debts 2). While deal numbers are not known relating to how much carbon dioxide solar power produces, it is known that it is much less than amounts from nonrenewable sources. However, this carbon dioxide can be removed from the atmosphere by being absorbed by plants as part of the biological carbon cycle. Unfortunately, all plants have a limit to how much carbon dioxide they can absorb, and all the plants in the world cannot absorb all the carbon dioxide just the U.S. produces (EPA 1).Solar power produces much less carbon dioxide than power plants burning fossil fuels, and there is very high technical potential. Technical potential refers to the achievable energy generation of a particular technology given system performance, topographical limitations, environmental, and land-use constraints (Lopez, Roberts, Heimiller, Blair, Porro 1). In other words, it is the amount of energy a technology can produce within strict parameters. The process for generating these technical potential estimate s is very exact, requiring convoluted calculations and surveying of the land. However, there are three different types of solar technologies, and the technical potential for each drastically varies. The three different types of solar technologies are utility-scale PV, rooftop PV, and concentrating solar power (CSP). According to NREL, utility-scale PV is generation of electricity through large PV (NREL 3). However, NREL has estimated that 3,212,324 km2 of land is available for utility-scale solar production in the U.S. (Anthony Lopez, Billy Roberts, Donna Heimiller, Nate Blair, and Gian Porro 10,11), out of 9,833,517 km2, which is the total land area of the United States (The World Factbook 1). This means 32.66% of U.S. land is suitable for production of electricity, which could produce up to 282,844,911 gigawatt hours (GWh) of electricity (Anthony Lopez, Billy Roberts, Donna Heimiller, Nate Blair, and Gian Porro 10, 11). In 2015, the United States produced 4.103 trillion (4,103,0 00,000) kilowatt hours (KWh) of electricity, which is equal to 4,103,000 gigawatt hours (GWh) of electricity (Philipp Beiter, and Tian Tian 7)i. In other words, using just utility-scale solar power plants, we could produce almost 68 percent of all the energy we consume using just solar powerHowever, many fossil fuel executives and politicians are opposed to solar power, among other reasons, because they say that it is costly and the construction of the solar panels still cause emissions. These critics are correct solar power is still costly and the manufacture of solar power does create emissions. However, historically, prices today are much bring down than those at the turn of the century. In an email from Jenny Chase, the head of the solar department at Bloomberg New Energy Financial, she stated that reductions in the cost of solar panels have to do with the experience curve. This means that the more of something we do, the snap off we get at it (Robinson Meyer How Solar and Win d Got So Cheap So Fast 2). Cost cutbacks also have to do with manufacturers improving their craft of materials in photovoltaic cells, including an essential material called polysilicon. Prices for polysilicon got as high as $400 per kilogram. That enticed more manufacturers to get into the industry, creating a supply glut and a price crash (Robinson Meyer How Solar and Wind Got So Cheap So Fast 2). As a result, current prices are much discredit than prices from years ago.While solar panels themselves create very few greenhouse gas emissions, their production can, depending on where they are produced. According to Robinson Meyer, many solar panels are manufactured in Europe and China (Robinson Meyer The Solar Industry Has Paid Off Its Carbon Debts 2). However, the environmental situations in these two regions are drastically different, because China relies on coal burning for much of its electricity, and it has more or less lax environmental tributes. The EU European Union, on th e other hand, already heavily relies on clean energy, and it has a large and entrenched environmental bureaucratism (Robinson Meyer The Solar Industry Has Paid Off Its Carbon Debts 2). This means that solar panels produced in China are more than likely produced in factories strike a lot of energy and produce relatively dirty emissions (Robinson Meyer The Solar Industry Has Paid Off Its Carbon Debts 3. Meanwhile, in Europe, factories producing solar panels hold relatively little energy and produce cleaner emissions (Robinson Meyer The Solar Industry Has Paid Off Its Carbon Debts 3). However, China has toughened its environmental protection laws, as they attempt to curb pollution. This means that in the future, China whitethorn produce solar panels with fewer emissions.If you dont believe solar power is the better choice for producing our electricity, there are other options to choose from that still protects our environment, including wind, geothermal, tidal, hydroelectric, and bio mass. However, if none of those options suit you either, then think about the consequences of using nonrenewable sources. Pollution. Changes in global weather patterns. Flooding. Drought. Desertification. Health consequences. These consequences spell out the destruction of the planet we live on. It may take years, but with continuous reliance on fossil fuels, these effects are inevitable. We still have a materialise to turn around, by using solar power, or other forms of renewable resources. Yes, this would require sacrifices and change. It would require courage to go against the status quo. It would require risk. barely if we chose to use solar power to generate electricity, we could make the world a little bit better. For ourselves, our world, and our posterity.Works CitedBeiter, Philipp, and Tian Tian. 2015 renewable Energy Data Book. 2015 renewable Energy Data Book Department of Energy.
