Coal, petrol, diesel, kerosene, natural gas - all of them are finite sources of energy. Considering the rate at which they are being used by people all over the world, they are surely on the verge of drying up sooner than later. Renewable energy sources, like the wind, water, and solar energy are the order of the day.
However, in spite of both, wind and hydro energy regularly being used all over the world in quite a few application areas, it is in fact solar energy that is being targeted as having the highest potential among all three. Therefore, on that note, let us have a look at all the pros and cons of solar energy.
Massive pumping stations and drilling grids are required to be set up for the extraction of fossil fuels from under the earth's surface. This results in an enormous setup cost and an equally high running cost as well. No such thing is required in case of solar energy. This energy is omnipresent, all that is required is a solar panel to tap it.
Fossil fuel prices constantly fluctuate, since they are dependent on certain global demand-supply factors. Solar power is completely devoid of any such complexities, simply because it is free!
The main disadvantage of solar power is the initial cost. Solar panels are comparatively quite expensive mainly due to the material cost and the complexity of design involved. This can at times, prove to be a deterrent especially in case of homemakers and individuals who are contemplating a shift towards solar power.
What about the time when there is no sunlight? How will solar energy be produced at night? Of course it won't be produced at night, after all it is solar energy and not 'lunar' energy. The only solution to this problem is storing enough of it during the daytime, which can then be used during the night. However, this is easier said than done.
Though solar energy does have its share of shortcomings, there is hope that in due course of time, they will be eliminated through advances in technology.
