subject: Positive and Negative aspects of solar energy [print this page] Solar energy has both positive and negative aspects. It has numerous advantages that make it the most important energy between all the natural sources of energy available. It has got some constraints also. But the fact is that there are so many positive points that it almost the negative points become almost negligible. This article is all about the positive and negative aspects of solar energy.
The various advantages of solar energy are-
Solar energy is highly abundant- This energy is unanimous. There will never be a scarcity of this energy. In winter season also, a moderate amount of this energy is available. That means this is a renewable source of energy that is consistent and will never end. This fact completes the search for a source of energy that is ever lasting.
Solar energy is free- We have not to pay anything to get this energy. It is absolutely free. Although a small investment have to be done at the starting but afterwards no body has to pay anything to get the energy. It can satisfy the energy requirements effectively with no expenditures.
Solar energy is clean- The most important advantage of this energy is that it is absolutely clean. Slowly and gradually it has become the best alternative for fossil fuels and nuclear power that will never be short. Solar power can be captured without making noise. Hence, we can say it does not make any type of noise pollution. Wherever there is sunshine, solar power can be generated. It does not require any special laboratories. In the production of solar power, there is no production of any green house gases, carbon-dioxide and other poisonous gases. Hence, it does not aid air pollution.
Some disadvantages of solar energy are-
Solar energy is totally dependent on the sun. If the weather changes to cloudy and when night appears, the extraction of solar energy comes to a halt. Solar panels are expensive because of the materials with which they are made of. To set up solar panels, a huge investment is required. If there is lots of sunshine, then only solar energy can be obtained and the places where lesser sunshine is present, this energy cannot be obtained.
