International business - Essay Example Combustible energy sources like coal, oil and wood emit environmental pollutants and contaminants. Only those sources that offer minimal contamination to the environment are deemed acceptable if they are to be sustainable. The sun is the cleanest source of energy with its free-of-charge irradiation and easy access all over the world. The sun’s irradiation can be converted to usable energy via hybrid conversion, simultaneously, into electrical and thermal energy (Afgan, 2008: p240). This involves the use of hybrid collectors that differ from thermal collectors due to the construction of their absorber, with solar cells, water flow tubes, and a metal system. The collectors can be used in hospitals, private companies and small industries. Compared to ordinary solar panels, the hybrid collector ensures better usage of space, savings during construction and the simultaneous conversion of solar energy into electric and thermal, current using one device. They are contemporary and eco logically clean. Sustainable development can be defined as the as the integral cultural, social, technological, and economic development that is adjusted to the requirements of environmental protection, thus enabling present and future generations to satisfy their needs and improve their quality of life (Afgan, 2008: p242). The underlying principle of sustainable development is the creation of an effectual system of distribution and application of resources over the long-term. Sustainable development focuses on the rational use of the earth’s natural treasures, with the concept oriented towards life upgrading and improvement of environmental quality. In order to accomplish sustainable development, there is a need to provide sustainable energy. This means that future development needs to be based on the lowering and strict control of environmental emissions and the use of renewable and clean energy (Afgan, 2008: p243). The cleanest source of energy that can aid in the achievem ent of this goal is solar energy. For five billion years, the sun has been sustaining and enabling life on earth. The sun’s rays have provided energy for growth, as well as development, of plants via the process of photosynthesis. Now, it is time for the sun to power our industries and drive development around the world as a sustainable energy source. Key Words; Solar energy, solar collectors, sustainable development 1. SUSTAINABILITY Solar energy is one of the main sources of clean and sustainable fuels. The main source of power or the fuel is suns rays that falls on the earth. Solar collector that is used to generate power using suns rays is essentially a sustainable system. The main reason as to why this is called sustainable is that the energy source continues to provide limitless energy. Unlike finite sources of power such as oil or coal, there is no depletion of power. While creating energy, carbon is mot emitted in significant quantity. It is true that some amount of c arbon is released and conventional power consumed while making the solar panels and solar cells and while manufacturing components such as solar collectors, inverters, batteries, electrical lines and cables and other such components. However, these are one-time costs only. The process of power generation and consumption remains sustainable and perennial. It meets the definition of sustainability where the needs of the present are met and the needs of the future generations are not compromised. There is almost zero impact on the environment due
