Solar Energy; An Alternative Energy
Solar energy can be used and is used for electricity, central heating, hot water, cooking, producing salt, and even desalination. Solar energy comes from the suns rays. Solar energy is known to be very environmentally friendly. However, when the sun rays enter the earths atmosphere it is quite dilute.
Although solar energy is known to be very environmentally friendly it does not only have advantages but also some disadvantages. Lets discuss some advantages and disadvantages of solar energy.
Lets start with the main advantage of solar energy. Solar energy is clean. To produce electricity or heat with solar energy you only need the sun’s rays. There is no need to use fossil fuel in combination with sun rays to produce electricity or heat. You just need a solar energy collector or solar power panels in order to collect solar energy.
Solar energy is cheaper than electric heating. That is another big advantage of solar energy. By just using solar energy you can save a lot of money on heaters. In return, you will get lower electric bills and it also means that you dont have to maintain heaters.
If you live in a remote area where there are no power-lines solar energy can be the solution. There are remote areas where power companies have no means to access your home. Solar energy is a great alternative because it provides you with anything from heating water, electricity, and even cooking.
Another great use of solar energy is for desalination in areas where fresh, drinkable water is scarce. Solar energy evaporates brine and leaves salt crystals at the bottom of the basin. The water, in turn, condenses back in another basin where it is now drinkable.
Although all of the above is very useful solar energy also has some disadvantages. These disadvantages also need to be discussed to paint a better overall picture.
The main disadvantage of solar energy is that it’s diluted. This means you have to have a lot of solar collectors installed around your house. Solar energy may be very cheap but the solar collectors are relatively expensive and require regular maintenance in order to work properly and efficiently. If you decide to use solar energy you need to calculate the return on investment in order to know if the investment will be worth it.
One big disadvantage is that you need the sun’s rays to make use of solar energy. If you are situated in a part of this beautiful planet where there is not much sunlight then this could be a problem. In other areas, the sun rays are almost always covered in clouds making solar energy collectors less efficient. You should first know if the sunshine in your area is abundant for the most part of the year. Of course, if you live in desert areas like in Arizona or Mexico the sun produces a lot of sunshine for the most part of the year and is ideal for solar energy collecting.
Lastly, the sun only shines during the day. Therefore if you need electricity or hot water during the night, like many of us do, it can be a problem. You will need a backup system like the old utility grid or you will need to store the electricity for later use. There are battery systems that can store solar energy for later use.
Solar energy is very clean and an alternative to conventional heating and electrical systems. Although this is true it is also good to mention the disadvantages of solar energy. If you are considering using solar energy you must read this first to make a balanced decision .
Hi My name is Abd Allah i am web content creator and renewable energy phd engineer.
I started blogging since 2 years what make me create this blog is the importance of sharing information with readers who love this field, I think i m not the first one who is familiar with this field but every person has his touch.i love nature and i think renewable energy will take over the responsibility of preserving this beautiful world.
