Almost everywhere there is technology, and what does technology require? Energy. Such a simple answer, but where does it come from? That is a question many tend to overlook. There are many energy resources that are being harnessed in this modern age, all of which are truly interesting in their own special ways, but solar energy seems to stand out. The idea that mankind can concentrate the Sun’s light and turn it into energy for personal use is very interesting. Although solar energy does have its drawbacks, its importance and potential should not be ignored. It has huge promise as developments are being made everyday. There is a chance that solar energy could very well be the solution to the current energy crisis that faces mankind. As time has passed, even over the past decade, its presence has increased. There are also many advantages of going solar, and because of its availability it is being harnessed in many different regions all around the world. From its primitive beginnings to now it has undergone many dramatic changes, and if it continues to evolve it may just make the future a brighter place. Society is too dependent on the fossil fuels. They have been used for hundreds of years and are still the major producers of energy. They include coal, oil, and natural gas. Except for a few exceptions society has been barreling forward and burning up the fossil fuels without stepping back and considering the consequences. Because of this the world is
One of the problems is that fossil fuels are non-renewable. They are limited in supply and will one day be depleted.
Why are we as a global society so hooked on fossil fuels? Put simply, we can’t live without it. Few people-- outside of aspiring reality TV stars and the Amish-- would be willing to give up their precious electronics and
Solar industry has been paying lots of attention to coating technology in the past 10 years. Solar energy is considered the future of alternative energy sources. It has been recognized as one of the most widely used renewable sources of energy in the few recent years for its non-polluting characteristics which combats the Greenhouse effect on global climate created by the use of fossil fuels, figure 1.6. The generation of solar power is done by converting the solar energy into electricity by using either photo-voltaic (PV) solar cells (direct method) or concentrated solar power (CSP). Photoelectric effect is used by PV cells to convert solar energy into electric energy. With the rapid growth of solar energy harvesting as a clean source of power, the enhancement of solar cell efficiency grabs more attention nowadays.
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
When all of our natural fossil fuels are low or gone, solar energy will be one of the leading sources of energy that we will need in the future.
Not only the problem of lack of resources but also but also they pollutes the environment. If the fossil fuels are used in this way for some more years ,It may difficult to breath in the future and many things which are harmful to the earth may happen like global warming .this may leads in danger to the lives of creatures.
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.
Coal, oil, and natural gas make up the list of major fossil fuels. Almost all energy produced in the United States comes from burning these highly important fuels. That energy powers almost all of our electricity and all of our transportation. We as the people of this very planet are currently in a crisis because fossil fuels are non-renewable; once they are gone, they are gone. There is no chance of recreating them for more use. To be able to rest easy about losing these fossil fuels, alternative fuel sources need to be found that can substitute efficiently
Fossil fuels are essential to life on earth as we know it today. Our world would certainly be much different if it weren’t for such seemingly simple things such as coal, oil, and natural gas. These basic elements of life on earth may not seem like a major concern to some people until we put into perspective how they have shaped our world today. Civilizations have been built, economies have risen and crumbled, and even wars have been fought over these precious fossil fuels. However, these fossil fuels serve us in ways we may never truly appreciate, as long as we use them as recklessly as we do now. The major entity about fossil fuels is concerning their longevity and permanence in our world, and we all know, they will be around forever.
Solar energy is the most plentiful and purist renewable energy source available. Because it is completely natural, it is considered to be a clean energy source. It does not disrupt the environment or threaten the Eco-systems the way oil and some other energy sources tend to. Nor does it cause greenhouse gases, air or water pollution. Solar energy is an immensely important aspect of life and has been since the beginning of time. Increasingly, we are learning how to harness this important resource and use it to replace traditional energy sources. Modern technology can utilize this energy in a variety of ways, such as; generating electricity, providing light or a comfortable interior environment, and heating water for domestic, industrial, or commercial use. One day solar energy may well become our primary form of energy. This would lead to a clean environment, less money spent on utilities, and a healthier world. It is highly important because it has the potential to allow technology and nature to co-exist peacefully.
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.
Interest in solar energy has been growing in recent years. Solar energy is abundant, clean and renewable. There are two main methods to tap solar energy, i.e. with PV cells and with solar collectors. The former converts sun light directly to electricity while the latter collects the solar thermal energy (heat) to be used for various applications. Solar collectors have been in existent for many decades. Their usages are experiencing resurgence in the recent years due to the interest in renewable energy sources. Strongly increased number of solar heating plants have been built and are under construction throughout the world. The solar collectors used in the solar heating plants are flat plate solar collectors and often the volume flow rate through the collector field is varying. The integration of solar thermal systems into buildings to meet energy requirements of buildings (for domestic hot water, space heating, air-conditioning and lighting) is supported by many researchers in different parts of world. Many types of solar collectors are commercially available; they differ in design and performance and, of course, in price. They have to meet different demands in operation, configuration and meteorological conditions.
Solar power harness the sun 's energy to create electricity. Solar energy assets are enormous and boundless, and they can be tackled anyplace that gets sunlight. The measure of solar radiation, otherwise called insolation, coming to the earth 's surface consistently is more than all the energy at present devoured by every single human activity yearly [1]. Various variables, including geographic area, time of day, and current climate conditions, all influence the measure of energy that can engage in for electricity creation or heating purposes.
Basically, first, we cannot consume the energy that is coming from fossil fuel for a long time because it leads to depletion that source. Another concern is climate change that is to give us a main indicator to redefining the energy security (Crowley2000 cited in HEZRI &WILHELM HOFMEISTE, 2012).
