The use of energy is increasing tremendously day by day. Hence there is bound to be a growth in alternative energy in order to meet the high demands of the modern society. What does the term alternative energy imply? The answer is the energy that is obtained from those sources that do not use up natural resources, or harm the environment, is termed as alternative energy. It is that type of energy, which is used to replace a different source of energy, often because of the negative consequences of its use.
What are the reasons behind the growth in alternative energy? Let us see for ourselves. Save plants and save the earth is the motto of the modern world. Various efforts to reduce pollutants and greenhouse gases are a primary focus, in today’s culture. Growth in alternative energy promises to bring down the toxins in the air that are the by products of energy use, along with preservation of natural resources that are used as sources of energy.
We shall now find out what types of alternative energy is found, and how they can be best utilized. They are namely
- Wind power: The energy generated by wind helps to propel the blades of wind turbines. This rotational movement of the blades is converted into electrical current, by means of an electrical generator. It is pollution free, and there is no left over by-products. This growth in alternative energy is a renewable source and therefore, there shall never be any shortage of supply.
- Solar power: This has also led to effective growth in alternative energy. It works by trapping the suns rays into solar cells where this sunlight is then converted into electricity. This energy can be efficiently used for practical purposes like heating and lighting. It does not release any water or air pollution as there is no chemical reaction.
- Geothermal energy: The growth in alternative energy like geothermal energy, harnesses the heat energy present under the earths surface. It is used to power electric generators. There are no wastes or left over of any kind and is therefore free from pollution.
Researchers are ever working on such theories that will reduce the use of energy, which if exhausted, will be a threat to the entire living world.
Hence the steady growth in alternative energy is extremely useful for the environment, and mankind at large, as it helps to protect and conserve Mother Earth.
