Whether we want to admit it or not, we use solar energy every single minute of our existence. Life as we know it would not exist without the constant input power of the earth from the sun. Solar
energy is needed for photosynthesis in plants for sunlight and warmth
to any living being, and for various complex processes take place on the
planet. This is the natural use of energy that is free from the sun.
However, if we use the term "solar energy", especially, we generally refer to the process of tapping energy from the sun and convert into another form of energy to different needs. For example, photovoltaic cells are used to convert solar power energy power for homes, offices and industrial plants. Heat is another form of energy that can be derived from the sun. Solar heaters and solar ovens convert light and solar radiation into thermal energy to heat water or cook.
Most of the energy that. Well our lives today from fossil fuels, which will be a non-renewable source However, heat and light from the sun to the earth have been casting around for ages, and it probably is not exhausted in the foreseeable future. Therefore, a reliable and inexhaustible energy source. As long as the sun rises every day, the human race may depend on it to tap power for different needs.
Besides being a non-renewable, fossil fuels also rise to pollution of the atmosphere. Automotive and industrial processes that emit operated petroleum-derived fuels, exhaust gases, the environment and continue to pollute the atmosphere at an ever increasing rate. With the proliferation of automobiles and the rapid industrialization of the world, this trend is only set to increase in the future.
On the other hand, solar energy is clean, since they do not produce byproducts which are detrimental to the environment. Especially if light and radiation from the sun is converted directly into heat energy for heating, it produces no pollution whatsoever. On the other hand, the electricity from the power of the sun is much more expensive due to the complexity of solar cells is required for the procedure. Solar energy is abundant only in tropical and subtropical regions of the world throughout the year. The arctic and polar regions receive very little sunlight and may not be able to rely on the sun terrace for their energy needs....
