It is massive, nonthreatening to the environment and, by and large, harmonious with daily and periodic energy demands. Solar energy, which generally comes from the suns heat and beaming light, has been…

solution to the most critical problems that the world has today, especially in reducing the concentration of carbon dioxide in the atmosphere, which deteriorates global warming (International Energy Agency, "Solar Energy Perspectives"). Solar energy is, by far, the most experienced form of energy due to its accessibility, and the ease of converting solar energy to electricity. Many solar energy conversion technologies present sustainable and promising potentials in providing renewable energy that does not only reduces the cost of electricity but could also deliver effective mitigating solutions to the environmental problems we have today.
The International Energy Agency expresses its confidence over the positive impacts that solar energies could bring to the world. The agency states that the creation of low-cost, unlimited and untainted solar energy technologies will have "huge longer-term benefits" (International Energy Agency, "Solar Energy Perspectives"). The energy agency adds that the stable generation of solar power through the use of solar energy conversion technologies will ensure energy security in many countries; and will cut dependence on power plants that use radioactive materials, which are potentially pernicious to human health. It will also lower down the energy cost, improve sustainability, will help reduce pollution, and will lessen the effects of climate change. Therefore, the agency stresses that since this innovative approach requires substantial amount of financial investments, a careful planning must be employed for an efficient expenditure of financial resources (International Energy Agency, "Solar Energy Perspectives").
Normally, the Earth obtains a sizeable load of radiation from the sun. On average, our planet takes at least 174 pent watts of solar energy (Smil 240). Of this, 70 percent is absorbed by the Earth by the clouds, oceans, and ground forms including the mountains and the plains among others. The sun’s rays could either be

Introduction Any discussion of problematic trends in contemporary energy industries has to begin with an analysis of the international petroleum system. Oil consumption, which currently provides majority of the world’s commercial energy, is again on the rise.
However it should not be ignored that the companies are also a very strong integral part of the process, quite a big chunk of the energy used is by the organizations and their factories, unless they are turned towards rethinking their strategies and incorporating sustainability into their system, the whole process will deem to be useless.
The issue is being analyzed from technical, economic, environmental and political perspectives, with a number of arguments coming in favour of the use of alternative energy resources as well as arguments against it. In the sections below, the arguments made in favour as well as against the substitution of alternative energy resources for fossil fuel resources are identified and discussed.
The study examines regions having alternative energy resources and their quest for the optimization of energy. The most recognized alternative methods of energy are nuclear energy, Hydropower, Bio diesel, Biomass, Geothermal, Solar hot water, Ethanol and Biomass electricity production models. The paper examines the impact of energy production models.
For over a century after their inception, their availability was very seldom called into question. The oil crisis of 1973, however, brought this issue to the forefront. With the widespread knowledge that the supply of oil and gas would eventually
One of the major challenges facing modern-day organizations would be the best possible ways for obtaining energy to support operations including production, heating and lighting and delivery of products, and services. The global energy demand has been noted to be increasingly high while the energy deposits of fossil fuels continue to be fast depleted.
Almost one-fifth of the electricity in the world being supplied by hydropower, it exceeds by far other renewable energy sources contributions; hence, making it particularly essential in the reduction of energy-related carbon emissions. According to Gatte and Kadhim, USA is
ented in the Bambui experience, it is evident that the community needs a reliable alternative source of energy after the collapse of the hydroelectric project. The alternative energy supply system as proposed shall make use of natural resources like wind and sunlight . For
