Solar energy refers to the radiation emitted by the sun, which is generated by the nuclear fusion reaction among the hydrogen atoms in the Sun’s core. Solar energy is the principal source of energy that reaches the Earth and is the reason for the very existence of the wide…
ss of the lost radiation, the solar energy that reaches the surface of the Earth is 10,000 times the energy used by the people (Solar energy in McGraw-Hill Concise Encyclopedia of Science and Technology, 2004).
The radiation which is scattered when it collides with gas molecules is termed diffuse radiation, whereas the portion that directly reaches the Earth’s surface is termed direct radiation. Clouds play an important role in the scattering of radiation and hence reduce direct radiation by 80 – 90%. Global radiation is defined as the total radiation, including the diffuse and direct radiation that reaches the Earth’s surface (Solar energy in McGraw-Hill Concise Encyclopedia of Science and Technology, 2004).
Extensive research is being carried on the utilization of solar energy; and the chief aim is to develop technology and discover efficient ways to capture the low-density solar energy, and convert it to a form that would be useful. In addition, forms of energy, such as wind energy, biomass energy, hydro power and thermal energy that derive from solar energy, promise to generate clean forms of energy. At present, with the sole exception of hydropower, none of these forms of energy are being employed to any significant extent (Solar energy in McGraw-Hill Concise Encyclopedia of Science and Technology, 2004).
Sources of energy that do not get exhausted and can be replenished are known as renewable sources of energy. Most of the renewable energy systems that are in use rely either directly or indirectly on solar energy. The direct sources include tapping the heat and light of the sun, whereas the indirect sources are wave power, hydroelectric power, and wind turbines (Renewable energy in Illustrated Dictionary of Science, Andromeda, 1988).
With growing awareness, regarding the ill effects and the limitations of fossil fuels, which will eventually be totally consumed, there is a sustained effort to change over to a more eco – friendly economy that is ...

According to the essay, solar energy is partially the cause of wind energy, as airstream conditions are significantly controlled by the sun. In addition, the sun is responsible for heating up the land to a considerable level in order to support the utilization of geothermal, ‘ground source heat pumps’.
It discusses the facts and application of Tucson solar energy as well. The nations of world have adopted various policies to extract opportunity from the solar source for the benefit of their citizens. Solar energy usage is diverse as it can be utilized for solar water radiator, solar thermal electricity, as well as solar cells.
Many homes currently use a type of solar energy that is not commonly known or promoted commercially to a large portion of the building industry; this is passive solar or climatic design. Passive solar homes range from homes that are heated entirely by the suns’ rays to those that incorporate south-facing windows that provide a small portion of the heating load.
However, the use of conventional fuel types is not sufficient anymore to meet the increasing needs of the population, and with the growing concern for the environment, the use of these fossil fuels is frequently frowned upon, owing to their voluminous carbon foot prints, that is, the capacity to release green house gases (Eltawil, Zhengming, and Yuan 2009: 2246).
Solar energy is often used as opposed to other conventional sources of energy as it emits little or no carbon dioxide to the environment. Due to this high demand for a safe and desirable source of energy, large-scale solar projects are expanding into an extensive range of locations and ecosystems.
In the recent times, more and more Arab countries are considering ways to become more environment friendly and greener. A very important idea of the Arab countries in the present age is to drive their plans of concentrated solar power (CSP). Two transmission projects and nine CSP plants with a total power of 1.2 gigawatts are expected to be fully operational in Egypt, Jordan, Algeria, Tunisia, and Morocco by the year 2018 (“Concentrated Solar Power”).
This project was started by BP Solar Australia which has approached the Philippines government with a concept for large-scale implementation of solar power across rural communities and received a favorable response. I will elaborate this project to find the main stakeholders of this project and to determine the basic needs of project governance.
These panels are composed of unique cells which capture solar energy which is then used or stored in other devices for later use (Benduhn 4).
There are many advantages that come with the use of solar energy. Apart from being a
Fossil fuels are the most popular energy source even though other sources of energy are available in this world. One of the most difficult problems associated with fossil fuels is its non-renewable nature. It should be noted that energy sources are
The early improvement of sun-powered advancement started in 1860’s and was determined by the assumptions that natural occurrence of coal will get utilized and will become rare. Nonetheless, improvement of sun oriented innovations stagnated in the early twentieth century notwithstanding the expanding accessibility, economy, and utility of coal and petroleum.
