Sun is the supreme source of energy on earth, and the sunrays fall on earth’s surface daily, generating energy which makes the life on earth conducive by controlling the weather on earth (Energy Producing Systems 33). Solar energy is described as a process of converting…

growth in the field of solar energy is remarkable due to the improvement of technologies and by the support provided by the policies implemented by the government in the field of development of solar energy and its use (Timilsina, Kurdgelashvili, and Narbel). There are mainly 2 types of technologies to generate solar energy, and they are: solar thermal and solar photovoltaic (PV). The former deals with the conversion of solar radiation to heat, or also called as thermal energy, and the latter is the technique which deals with converting sunlight directly into electricity (“Chapter 10: Solar Energy” 263). The solar thermal technology is again divided into two such as solar thermal non-electric and solar thermal electric (4).
Solar thermal non-electric technology is used in solar cookers, solar water heaters, solar air heaters, solar coolers, agricultural drying, etc. On the other hand, solar thermal electric technology is the method of directly using solar heat for the production of steam for generating electricity, which is otherwise known as concentrated solar power (4). Currently 2 types of PV technologies are present in the market, namely thin film technology made up of different types of semi-conductor materials such as cadmium telluride, copper indium gallium diselenide, amorphous silicon, etc., and the second technology is called crystalline silicon-based PV cells (4). The history of solar energy begins between 1860 and the First World War, when a wide range of techniques were established to generate steam by obtaining sun’s heat so as to run the irrigation pumps and engines (4). In 1954, at Bell Labs in the United States, Solar PV cells were used for generating electricity in space satellites (Timilsina et al. 4).
The energy provided by the sun can be directly collected and used to make high temperature steam, i.e. more than 1000 C, and low temperature steam, i.e. less than 1000 C (Energy Technology Fact Sheet). These methods are implemented in

A long distance is covered to the surface as the energy transforms and is released as its primarily light energy, sunlight. The two forms of solar energy that make it to the earth are light and heat. Solar energy is often termed as alternative energy to the fossil fuel energy sources like oil and coal
This alternative choice is solar energy. This proposal seeks to bring insight of solar energy to the matter at hand. The suggested option will be elaborately discussed in the subsequent sections. Problem The UAE relies entirely on oil in order to generate power.
Solar energy is very important to maintain life on earth, it facilitates the growth of food crops, control climate conditions, provide warmth, and can be utilized to produce solar electricity. Moreover, solar energy is partially the cause of wind energy, as airstream conditions are significantly controlled by the sun.
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”).
While there are several benefits to consider when choosing alternative energy, very many people are failing to recognize the lasting benefits renewable energy would have on the environment in the future.
Non-renewable energy resources, including
The author states that solar energy has many advantages in Hong Kong since there is abundant sunlight. High-rise and high-density urban environment often create difficulties for energy applications. There have been interesting results derived from using solar systems. Wind and solar energy have been proposed to be used in the "Hong Kong Disneyland”.
