Thomas Edison once said, “I have not failed 10,000 times. I have succeeded in proving that those 10,000 ways will not work,” he said of his method of experimentation. “When I have eliminated the ways that will not work, I will find the ways that will work.” Up until the late 1830’s electricity was derived from many non-renewable sources such as coal, oil, and natural gases. These are also known as fossil fuels. Fossil fuels are the major energy sources that are being used in the world today. The production of fossil fuels account for more than one-third of U.S global emissions, which trap heat, steadily drive up the plant’s temperature, and create harmful impacts on our health, our environment, and our climate. Their sources are limited and depleting at a faster
Solar energy is the most ancient kind of energy found on earth, for it is as old as the sun. "Solar" means from the sun. The earth is only one of the many planets which is bathed in the sun's overflowing energy. Every second the world receives 95.8 trillion watts of power…just think about that for a minute. Think about how much power the earth just received in the time it took you to read this sentence? It is well beyond the amount of power used in one day. It has the potential to satisfy all our energy needs forever without ever having to use the pollutive fossil fuels ever again. "The problem however, does not lie in the limited source, as do fossil fuels, but in harnessing
The heading of the article gives clear information about the content of the article and study purpose. Research article has a formal appearance. The source is well structured in a good order with a graph and three tables. It has a decent length and rich content. The origin of the source is well-known as well as the names of the contributing authors.
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
The background and significance of this study are properly presented in the introduction. The research question is presented at the end of the
For the readers to have clear understanding of the article, it is empirical that the researcher defines the given research topic precisely. Hence, the chance of accomplishment in a research project is greatly improved when the opening is correctly defined as a precise statement of goals and rationalization. Even though Snipelisky and Ziajkas’ definition of the topic article relates to the main subject of the research study, examining the whole article content and presentation, it is impossible to reach conclusion that this study to bear the credibility it claims. Hence further research is
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.
It is important to mention at this stage that a research study presented by a researcher may not give complete information about the selected topic. There can be certain limitations of methodology and the new researchers may criticise it for being incomplete. As research is a circular process in which ideas can be added and extracted by researchers anytime, the application of the presented ideas by one researcher are tested and verified.
Solar power is one of the most environmentally benign energy sources available. Just 20 days of sunshine produces the same amount of energy as everything stored in Earth’s reserves of oil, coal, and natural gas—yet does not come close to producing the same amount of environmental damage as even one of those options (Greentips, 2005). Solar farms are a clean renewable source that can meet high energy demands and can creates thousands of jobs in the future. It is also used during peak demand for electricity. During the hottest days, the panels are absorbing more energy while homeowners have the a.c. on full blast. They can be installed anywhere
The research has made use of a number of academic sources so as to get some historical and current information concerning the topic. The importance of using the academic sources is that they are reliable and contain information that has been gathered by many writers thus making the research very successful. The
Much like the glass of a greenhouse, gases in our atmosphere sustain life on Earth by trapping the sun 's heat. The Earth’s atmosphere contains several different gases that act like a blanket, keeping the Earth warm. Water vapour and some trace gases like CO2, CH4 (methane), O3 (ozone), N2O (nitrous oxide), are “IR active”, i.e. they absorb heat energy, and stop the warmth from escaping into space. Without the entrapment of heat, the earth’s mean temperature would be -180 C and life, as we know it today, would not be possible. These gases are present in the atmosphere in tiny quantities compared to the amounts of oxygen and nitrogen. But even a small change in the concentration of these gases may create an effect that could change our
The methodology of the research is qualitative hence secondary resources such books, reference materials, on line articles on BI, IT journals on PDF served as the basis of discussion. Five people were also interviewed to solicit their personal views
The greenhouse effect refers to circumstances where the short wavelengths of visible light from the sun pass through a transparent medium and are absorbed, but the longer wavelengths of the infrared re-radiation from the heated objects are unable to pass through that medium. The trapping of the long wavelength radiation leads to more heating and a higher resultant temperature. Besides the heating of an automobile by sunlight through the windshield and the namesake example of heating the greenhouse by sunlight passing through sealed, transparent windows, the greenhouse effect has been widely used to describe the trapping of excess heat by the rising concentration of carbon dioxide
Abstract: The current energy situation with fossil fuels as the main source of the world’s energy has two main flaws: fossil fuels contribute to global warming via the greenhouse effect and they are limited in the quantity that remains. Solar power solves both of these problems and can be captured by utilizing photovoltaic cells. However, photovoltaic cells have their own drawbacks due to their high costs of installation and maintenance.
