Pros And Cons Of Solar Energy
Learn how solar energy is generated and discover hidden secrets of gaining from this powerful energy source.
Learning about solar energy and how it is generated
Solar energy, as the name itself suggests, is derived from the sun and is sourced from the radiant energy that is emitted by the sun. Solar energy thus obtained is transformed into various other useful forms of energy such as electricity, heat, light, mechanical and chemical power, and used for a most diverse range of purposes. The radiant energy is emitted through the rays of the sun which are primarily made up of radioactive waves. Of the entire amount of sun’s energy incumbent on the earth’s surface, the upper layers of the planet usually absorb around 70% of it through the various water bodies, landmasses and the atmosphere, while the rest is reflected back into space. Solar energy is an important alternative source of power for today’s world and is finding wider acceptance everywhere with every passing day. In this respect, it is of much importance to learn about all the pros and cons of solar energy.
What are the plusses and minuses of solar energy?
It is reassuring to see that solar energy is getting accepted widely by more and more people everyday and is finding newer applications and uses with every passing day. Apart from the already popular and widespread domestic use of solar power, it is also being used extensively in various other fields such as agriculture, architecture, urban planning, solar lighting, solar thermal, solar chemical, solar vehicles, cooking and so on. Based on how solar power is being used, it can be broadly divided into two classes - active solar power and passive solar power. The former is essentially all about using solar panels and photovoltaic cells to capture and convert the sun’s energy into various forms of energy, while the latter is more concerned about reducing the dependence on alternative power sources and instead, directly use the natural light and warmth of the sun by citing buildings optimally to the sun, designing well-lit and well-illuminated spaces in the buildings and so on. The fact is that solar energy has become an integral and inseparable part of our daily lives. Unfortunately, the general public ignorance about this marvelous source of power is surprising!
Compared with the many advantages of using solar power, the disadvantages of solar energy seem few and rather trivial. Let’s take a look at the pros of using solar energy first. There’s hardly any doubt today about the fact that solar energy is really an excellent alternative source of energy and thanks to modern science and technology, it is now possible to tap into this vast resource and harness a part of it to put it to various uses. The best thing about solar energy is that it doesn’t cost a thing, and after the initial setup costs, there are no further expenses. The natural reserve of our energy producing resources such as coal and petroleum is fast getting depleted. As a result, alternative sources of energy are being looked into with renewed enthusiasm. Moreover, this completely pollution-free, environment-friendly and ‘green’ source of energy is a great choice for saving the environment. Solar power also offers a great deal of flexibility and easily allows itself to be set up at very remote locations, even in satellites in space, and yet produce power with amazing efficiency. This further means that solar installations can be made in rural or remote areas for more economic and social growth. Recent advancements in solar power technology have made it possible to generate appreciable amounts of power even when the sun is not shining very brightly. To add to the convenience, the energy produced during the day can also be stored for use at night or during a dull cloudy day.
Benefiting from solar energy
Let’s take a look at some of the disadvantages of using solar power. The most serious complaint against its use is the high cost associated with it. Solar panels and other related equipment are usually quite expensive. Even the cheapest of solar power generators would easily cost one no less than a grand. Another problem of using solar power is the fact that most solar systems are not yet capable of generating sufficient amounts of electricity under less than optimal circumstances. In other words, a steady supply of bright sunlight for a fairly long stretch of time is something that is absolutely required by most solar systems today to be of any real use to us. Moreover, their performance can get seriously affected by the presence of pollutants in the air. In fact, few solar power systems today are able to give 100% output because of this reason. This is also the reason why installing a solar power generator at a remote locality usually makes better sense as it yields more output than in the city where the level of pollution is higher.
Solar power is really a great choice for reasons both financial as well as environmental. That is why so many people are enthusiastically considering installing a system in their homes. The best thing is that you can too. But for that you need to know where to put it up, how to install and wire it, where to get the parts and the batteries from and also the safety regulations that have to be followed. A step-by-step guide in this respect can be really helpful. You should seriously consider getting hold of one such good guide before you take the plunge into the wonderful world of solar power.
