Extract of sample "Solar energy"

Download file to see previous pages Solar energy is the power that is produced directly by the sun and collected somewhere else, mostly on the Earth. The sun is the nearest and biggest star and the source of energy for the planet of Earth. The sun's energy has been in use for a lengthy time, and it is a critical part of life. The solar energy is a fundamental need for humans. The image of the sun has many theories, histories and myths associated with it. For centuries, it has been the God, or the holy part of different religions, for example, the American native tribes and Greeks worshipped it. It is also an essential part of many religions as they hold it dear to their worship, for example, Hinduism, Buddhism and druids of England hold the sun as the precedence of their existence. It is a fact that without the solar energy, human life would be inexistent. Sunlight is crucial as the living organisms circle around it for survival. According to Mahaney (10), plants depend on sunlight for photosynthesis to take place, thus, helping in their growth while, on the other hand, providing food for animals. The sun and other stars are, in essence, responsible for providing human beings with energy. In the current climate, mounting power requirements and escalating environmental worry, unconventional to the exploit of non-renewable and polluting relic fuels, have to be scrutinized. An instance of energy that requires to be investigated is the solar energy (Tiwari 199). The sun produces its energy by a thermonuclear process that converts several tons of hydrogen to helium each second. The procedure produces heat and electromagnetic radiation as the sun retains the heat, which is instrumental in maintaining the thermonuclear reaction. The electromagnetic radiation is distributed and streamed out into space in all directions. These rays entail noticeable and infra-red, as well as ultraviolet, light. From the radiations produced, only a little fraction manages to penetrate, and reach the planet Earth (Mahaney 4). The radiations reach the Earth in a form of indirect source of nearly every type of power used today. The only form of energy that does not rely upon solar energy is the geothermal energy and nuclear fission and synthesis. Even fossil fuels are reliant on the sun for their energy, as they were once live creatures and plants that utilized solar energy for their survival. Table of world energy usage as per the year 2000 Energy source Solar energy Electricity Fuel oil Liquefied petroleum other percentage 51.2 30.3 9.3 6.5 1.9 The table above shows world consumption rates of different sources of energy. Solar energy is the most utilized one followed by electricity, according to the table. The world’s most needed solar energy can easily be harnessed and completed by solar power. Much of it can also be supplied indirectly. Because of its nature, solar energy requires two components for it to perform; these are the collector and the storage unit. The radiations are gathered by the collector as they fall on it and convert a fraction of the radiations to other varieties of energy, such as electricity and heat. The storage unit holds the excess energy produced at maximum productivity and discharges it when the productivity falls. The storage unit is necessary because of the inconsistencies of solar energy (Tiwari 192). Solar energy is one of the most plentiful sources of energy, which is easily available to ...Download file to see next pagesRead More

Water and Energy Versus The Ideal US Population

...). Genuine concerns are expressed about consumption of energy and luxurious items by the United States and its impact on biodiversity and conservation efforts around the world. Yearly Americans are using twice as much fossil energy as the total solar energy captured by all plants through photosynthesis in the United States. Petroleum geologists warn of the approaching end of the petroleum and natural gas era, and even coal reserves are not inexhaustible. Furthermore, uncontrolled U.S. population growth, intensifying soil erosion and degradation on agricultural lands, the overuse of water resources, and pollution combine to reduce the carrying capacity of the ecosystem,...

Wave Kinetics and Tidal Energy as an Alternative Energy Resources

...Wave Kinetics and Tidal Energy as an Alternative Energy Resources No: Wave Kinetics and Tidal Energy as an Alternative Energy Resources The law of conservation of energy states, “Energy can neither be created nor it can be destroyed, it can be transformed from one form to another” (Denecke 2006). If we look around, we can find many resources of energy like the fossil fuel has the chemical energy stored in it and when it is burnt, the chemical energy transforms to thermal energy, which can be utilized for majority of purposes. Wind has also energy stored in it, which can be transformed to a usable form by utilizing windmills or wind generators. Similarly sun provides us both light energy and thermal energy. Both of the solar energy types...

Alternative Energy Sources: A Panacea to Oil Dependence

... and even support both, individuals and organizations, financially (McNamee, 2008). The changeover to renewable energy sources, along with helping in other ways, will also help in creating various job opportunities. There would be a requirement of the workforce in the factories designed for production and manufacturing of components for renewable energy sources. There would also be a need for educated and trained professionals for the service and installation needs of these components. Few examples of these components include solar panels and mechanism required for wind mills, etc. This way a whole new market will come into being, thus supporting world economy and helping individuals by creating employment opportunities (McNamee, 2008...

The Impact of Renewable and Non-renewable Energy Sources on Earth

...-energy use was mostly unproductive, socially inequitable as well as damaging to the health. It can be stated that wind energy has become cost competitive with traditional energies in leading countries. Among all the renewable sources energy, it can be mentioned that the geothermal energy is practically infinite in nature in the long-term and it is also considered to be an abundant resource in the developing countries (The National Academics Press, 2012). Solar energy does not lead to air pollution when it is operated. The primary environmental and safety issues related to solar energy comprise the way they are created, installed and disposed of. There is a need of energy to create and hence install solar components. The fossil fuels used...

Is Sustainability Energy a Realistic Goal in the Near Future

... include clean cooking fuel, electricity and an adequate means of transportation. Of course, the need for a profound transformation of the world’s energy-producing and using infrastructure has been widely recognized in the mounting concern about global climate change (Al-Saleh, 2011). Presently, for these services to be provided most of the energy has to come from fuels like coal, oil, nuclear, wood. They also depend on other primary sources like waterpower, solar or wind that until they are converted into the relevant energy services that can be used by mechanics and other end use equipment, such as turbines, stoves or motors remain largely useless. With the overview of the present energy sources and its limitations, it is very clear...

Solar Heating

...SOLAR HEATING Email: INTRODUCTION Mitsuo (1997, 63) holds that active solar heating applies solar energy to heat fluids. It transfers the solar heat to the interior space directly. It also transfers the same to a storage system for future consumption. Back-up systems as well as auxiliary systems offer traditional heat moments when the solar system does not give enough space for heating. Under storage devices, liquid systems apply and do well considering the radiant heating systems. Other instruments include boilers that have radiators for hot water. They add to coolers and absorption heat pumps. Forced air systems accept both air and liquid systems as supplements. Schiller Consulting, (2007, 21) on the other hand covers liquid-based solar...
