Advantages and Disadvantages of Solar Energy
With the over exploitation of the natural resources found on this planet, an obvious dearth in energy sources is on its way to make itself evident. The popular energy sources that we most often use, like petroleum and its by products, coal, etc are instances of nonrenewable energy sources. They have taken millions years to get into the shape they are today, and once exhausted, they cannot be refurbished before some other millions of years. Therefore, it is only too obvious to put other alternative sources of energy into use in order to sustain and maintain the rate of energy consumption as evident today.
Energy sources such as the sun, moon, water, wind, gravity and so on are being taken under consideration as alternative sources of energy and it is here that solar energy walks away with the crown of being the most efficient alternate source of energy. Solar energy, when enters the earth’s atmosphere, some part of it is radiated back to the space which then is lost. However, by effectively harnessing this power of sun, humans can put it to their most effective use in terms of driving turbines and moving gadgets. In fact, the photo-voltaic cells trap sun’s energy to produce electricity that is being used for lighting purposes all around the world.
The most widely used devices that run on solar power are the solar cooker, the solar water heater, solar powered lights and so on. The advantages of solar energy are beyond count and the three primary aspects involved in the wide usage of solar energy over other sources of energy are as follows: cost efficiency, the ability to be renewed, and pollution freeness.
Solar energy is free for all and, by making use of this energy; you can save a lot of money that you would otherwise spend for paying electricity bills. The second and a very important aspect is the ability of solar energy to be renewed. The sun is an endless source of energy for every entity within the solar system and the abundance of the light and heat that the sun is home is a never-ending source of energy. This very well replaces the other conventional nonrenewable sources of energy with much efficiency and removes the threat of exhaustion from over their head. The third and perhaps the most crucial of the three is that solar energy produces no waste and frees the environment from any unwanted polluting component. This makes a huge contribution towards pollution freeness and the revolution that is going around all over the world.
Solar energy, as far as one can gather and recollect, has no disadvantages. However, the only thing that is hindering the revolution to take gigantic turns is the cost of installation that is still beyond a common person’s reach. The cost of installing the photo-voltaic cells and the panels that trap the energy of sun, are quite high even today, though experts are making continuous efforts towards to bring it down. Done that, the world can breathe relief with the sun to take care. |
