Solar Power And Its Increasing Uses


In today's time of increasing pollution, eco-friendly products are preferred to be used. There are several ways in which one can make it possible. There is a lot of products that can be used to replace the older ones causing pollution. As every body, talks about “Go Green” and prefer clean energy, so we can use solar power that is easily available reduces, reduces pollution to a great extent and is eco-friendly.
Solar Power is generated by capturing the sunlight and converting it into energy and then use it in different forms. Usually, this process is of conversion of sunlight into heat or electricity. It is popular due to reason that it saves the fossil fuel which is near to extinction and causes pollution. It is a convenient source of energy and a reliable replacement to the traditional power sources. Its most advantageous fact is that it is renewable energy source. No one has to fear of its extinction. They will be available life long, as the sun will keep on shining till the existence of this universe. It is also a cheap source of energy. Thus, it is a good idea to use this energy instead of other sources, which will be, both expensive, causing pollution and will not last for long.
It has several uses of its own. They can be used in solar cells or for water heating or solar furnace or solar panels. solar cells also known as photovoltaic cells or photoelectric cells that convert solar energy into electricity. They are used on solar panels made up of silicon material that absorb sunlight and their reaction produces energy. They generate direct current(DC) and using inverters it can be converted into alternate current(AC) that is used in all places including our homes. This type of energy is so efficient that it can produce enough power to light up a 100w bulb from a single square meter of it. So one must promote the use of solar power to a great extent.

Future Scope of Solar Power


Solar power deals with the use of solar radiation for practical purposes. It has been employed in order to decrease the carbon footprints from our environment. It is the basic motor of all forms of energy generation methods. It is free and clean to use. This form of energy is available in abundance in our environment. The fossil fuels are also mere frozen solar power. Solar energy has remained a necessary ingredient for decades now. It's demand for usage still prevails.
It is mainly used for the domestic purposes these days. Solar power systems operate by converting the solar energy into the electrical energy. Usage of this power helps tremendously in reducing the power bills and also largely helps our environment. Using this form of power for domestic purposes has many advantages. The people who use it know it better. All of the people who use only solar power operated electric appliances do not wish to switch to other power systems.
For generating the solar power at our houses, we first need to install the solar panels on the roofs of the buildings, The solar panels are placed where their is ample amount on sunlight falling on them. Solar panels trap the heat energy and generate electricity. This form of power can be used to rum many home electric appliances. A traditional boiler can be used for heating the water when their is no sunlight.
The photovoltaic cells also play an integral role in our lives. They are basically the panels that you can attach it onto your roofs. With the sunlight falls onto them, the electricity is generated. Their are many sizes of solar panels available in the market today. The size is proportional to the amount of electricity to be generated. You must be watchful of the strength of your roof before installing the solar panels. For the generation of solar power at your homes, place the solar panels to the south.
The solar water heaters are primarily used to heat up the water for the domestic purposes. They are of two types: direct solar water heaters and indirect solar water heaters. To set up the solar panels, you just need to have little knowledge about plumbing and electrical wiring. These solar water heaters reduce the electricity bills and expenses. Solar panels create pollution-free environment. Solar power is the most flourishing form of eco-friendly energy. It contains no moving parts and generates no noise. It does not release any harmful radiations into the environment. This form of energy does not affect the human life as well as the animal life. It converts light form into electricity very silently. There is a particular disadvantage of this form of energy i,e its output variability, When their is no direct sunlight, these panels fail to work until their is adequate sunlight.
As the technology has advanced, we now have started making use of electric vehicles too. Such vehicles have started becoming readily available and are operated using battery technology as well as solar energy. Their costs are now dropping and such vehicles are becoming readily available to the masses. Electric vehicles have a wonderful future for sure as they do not pollute the environment. They are also cheap in their usage.

The Disadvantages of Geothermal Energy

Firstly, one of the challenges is that since this energy source is extracted from deep within the earth; the sites to build geo thermal energy plants are limited.

Secondly, Geothermal systems tend to have a somewhat higher first cost than conventional systems. However due to the low maintenance cost in the long run geothermal energy will cover the initial costs and deliver a good ROI (Return of Investment).

In regards to the economy, many of the geothermal resources are located around the world and thus geothermal energy is helping with job creation and economic stimulation of each country that can tap into this resource. Instead of relying on emission producing fuels, we can rely on something that is renewable, reliable and, most importantly, risk free to our future generations.
