The Environment And Environmental Impacts Of Solar Energy

In this modern fast paced world that we live in, there are many issues that are looked over, energy is one of these. As a world, we are dependant on dwindling fossil fuel supplies and take for granted electricity, oil, and gas. There are four completely renewable sources of energy around us that should be used and developed, they are: wind, growing plants, flowing water, and the sun. These sources of energy are the ones we should be tapping, because they are reliable and renewable. Harnessing the suns energy is the most certain and ultimate energy source. Looking at a brief history and some facts about solar energy, a glimpse of the future can be seen, a future not dependant on

Emissions from coal fired power plants contribute to global warming, ozone smog, acid rain, regional haze, and perhaps most consequential of all from a public health standpoint, fine particle pollution.

Most power plants burn coal, oil, or natural gas to turn water into steam. This steam make a turbine rotate which produces electricity. In a nuclear power plant, atoms are split creating heat to turn the turbine. Other power plants create many greenhouse gases, while nuclear power plants only release carbon dioxide. There are 100 commercial nuclear reactors in the U.S., these reactors account for about 20% of the nation's total electricity. There are 7,577 other power plants ( thermal, hydro-electric, geothermal, and wind power plants) not including nuclear power plants in the U.S. alone. These power plants - talk about pollution -emit carbon dioxide, ammonia, methane gas, boron, decrease oxygen supply, displace animals, and many other things.

On average the world us 39% electricity therefore, electricity consumption is an important portion of a customer’s environmental footprint, which leads to the production of Carbon Dioxide ( Co2) a few ways production of electricity has affected the environment is: The main sources that generate carbon dioxide are thermal powered stations where hydrocarbon fuel (gas, oil, and coal) are burned to produce heat and steam to drive to the generators. Hydrocarbon fuel is what causes carbon dioxide letting out chemicals that pollute the earth’s environment.

powerplants usually add chlorine or other harmful chemicals to the water they use, which means that these chemicals also get released back into the environment. Another negative impact is the amount of energy being created. Most of heat used for burning the coal and creating steam is wasted. Coal powerplants usually only use 33 – 35% of the coals heat to create electricity. The rest of the heat gets released into the atmosphere or absorbed by cooling water. This is negative as this sudden influx of heat could affect the climate in that area, if not the world. If we have millions of coal power plants (Keep in mind it produces 41% of the electricity) than whats not to say all that heat and other emission from the plants won’t cause global warming?

This is a pie chart about how much electricity was used by type. As you can see coal and natural gas have a much higher use. This causes a lot of pollution which will hurt the environment. "Coal is almost half the [global] emissions. If you replace these power plants with modern, safe nuclear reactors you could do a lot of [pollution reduction] quickly" from a Scientific American article.

Nuclear power plants do not emit the harmful green house gases and other negative by-products associated with the more conventional systems fuelled by coal and natural gas. Nuclear power plants use nuclear reactions to drive their generators. The reactions produce extreme amounts of heat that must be managed. Most

Coal-fired plants generate electricity through the combustion of coal. Whereas fuel used by nuclear plants use uranium oxide, UO2.Other than a source of energy, coal power plants and nuclear power plants produce energy in the same fashion.

While technology has led the world into such an advanced setting with intelligent machinery and automated devices, coal has remained a loyal contributor of the energy needed by these various types of equipment to function properly. Almost half of the electricity in the United States is produced in coal plants where coal is burnt to produce this energy [1]. Both beneficial and detrimental factors come with this alternative source of energy, known by the world for centuries.

Pollution is another topic with both pros and cons. Fossil fuels release harmful pollutants into the air such as carbon dioxide and sulfur dioxide. Nuclear power does not release any of those toxins into the atmosphere. However, a pollution problem with nuclear energy is thermal pollution, where a plant’s “hot effluents” are put into a nearby body of water, and raise the temperature by a small amount but enough to cause a disturbance in the ecosystem of the lake or reservoir. Nevertheless, this could easily be solved by cooling the effluents before releasing them into the water. The other problem facing nuclear energy is waste disposal. Nuclear waste is radioactive and very dangerous. Therefore, it must be kept buried and sealed up for a long period of time until the radioactivity dies [Plasma-Material]. One positive fact about nuclear energy that is not disputed is its abundance.

In addition, solar energy operational costs are manageable. It is free from monthly charges compared to conventional sources of energy. Solar energy does not require raw materials such as oil and coal, and once the panels are built, there will be no monthly charges. In addition, the prices of fossil fuels are increasing day by day, and this means conventional energy will be very expensive. Solar energy will remain the most capable world’s future power supply because, it is cost effective once the plants are built, and there will be no transport costs like for conventional energy sources. Therefore, solar energy is cost-effective, and will help in future energy supply, as the maintenance cost is affordable, as long as they are installed properly, and are working efficiently ( Hans, 2012). Furthermore, with the improvement and advancement of technology, it will increase its efficiency, and cost of production thus, making it more cost effective and the world’s best

CO2 is the most significant greenhouse gas, which mainly comes from the use of fossil fuels. Many people feel that content of CO2 in the atmosphere is the main reason for manmade global warming. The main sources of CO2 emissions involve electricity generation, industrial processes, fumes from transportation and commercial buildings and use. Emissions of greenhouse gases, such as CO2, to the atmosphere are expected to cause even more of a significant change in global climate (Davison, 2007). The main focus to try to reduce the amount of carbon dioxide in the atmosphere is to reduce the amount that is released from coal-fired power plants. Greenhouse gas emissions that involve the productions of electricity come from natural gas production and coal-fired power plant operations. Natural gas production accounts for twenty-four percent and coal-fired power plant operations accounts for seventy-five percent, while the other one percent is caused by other electricity generation operations. The main reason why coal-fired power plants have a higher percentage of emissions is because the sulfur content of coal is much higher than that of other fossil fuels (Jarmaillo et al., 2007). This proves that there is a great need to find an alternative fossil fuel to use instead of coal. Although coal is easy to mine, transport and process for the electricity generation process, it is also the

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.

Solar energy may define as the energy received by the earth from the sun. This solar energy is in the form of solar radiation. With the help of solar cells, solar radiation can convert into electricity. Sun is a highly powerful energy source, humans and natures are directly depending on the sun. For example in hydro-electricity the solar energy needed for the evaporation of water after that it returns to earth as rain and provides water in dams. In biomass, the solar energy used that process. Solar cells directly converted solar radiation into electricity, during the process time there is no noise or pollution are there. These cells made with some semiconducting materials. If use solar cells in our home it will help to reduce the greenhouse gas emission, minimise the percentage of carbon dioxide in our atmosphere and mainly reduce the necessity of fossil fuels and natural gas use to produce electricity. According to the Ben Sorensen, solar energy is one of a good source of substitute energy, for the reason that it is renewable, economical and does not pollute our environment. Thus, this essay will be divided into three parts. Firstly, we will talk about fossil fuels and its demerits. Secondly, we will look at the issues and implications of solar energy. Finally, we will focus on the advantageous and disadvantageous of solar energy respectively.

The world currently functions through the use of fossil fuels. However, fossil fuels possess two significant disadvantages. Fossil fuels harm the global environment because they enhance the greenhouse effect by releasing carbon dioxide, and they release other harmful
