Why is solar energy the best energy solution?

The energy obtained from the alternative energy source, the sun is called solar energy. The amount of energy produced on this planet is very small as compared to the amount of solar energy received by the earth which is almost 35000 times more than the former. A small fraction of the renewable solar energy is reflected back into the atmosphere and the rest gets absorbed. This absorbed solar energy can be put to many uses like heating homes, lighting homes and industries and running automobiles.

There are many reasons to consider solar energy as the best alternative energy source and a solution to the energy crisis. The first and the most important reason is the fact that solar energy is a renewable energy source and will be available for many years to come. Solar renewable energy is both biodegradable and sustainable. The generation of electricity by using the renewable solar energy requires no burning of fossil fuels and so there is no emission of harmful substances into the atmosphere. This makes the use of solar energy more popular because it is not hazardous for the health. The use of renewable solar energy helps to maintain an ecological balance and does not degrade the environment as it does not cause pollution. Another important reason that makes solar energy the best energy solution is that it is freely available. It can be used cost effectively for the generation of electricity.

To meet the energy crisis, the renewable solar energy must be utilized to its full potential.

Solar Power

Humans have been harnessing the renewable solar energy to generate solar Power for long times. They have applied this alternative power source to varied tasks. Various technologies are used to convert the renewable solar energy to solar power. Since this is a renewable energy source, most nations of the world opt for it to meet their energy requirements.

In order to extract this power, solar cells are used as the process of converting the solar renewable energy to solar power in solar cells is convenient and environment friendly. Solar power is harmless whereas the fossils fuels are harmful both for the environment and living beings as they emit greenhouse gases which are very poisonous. Solar power is also used by farmers to improve productivity of their land and crops.

The cost of maintenance of devices that are powered by this alternative power resources also less. Solar power is also used to generate electricity. In cases when excess electricity is produced from the additional solar power can stored in alternative power stores for future use.

Various technologies are being developed by scientists to promote the use of this renewable energy source. Steps are being taken to use solar power for satellites. Solar power is a versatile source of energy and can be put to a number of uses in a variety of appliances. Devices like heaters and cars can be powered by solar power. Solar power can be used for a very long time and is becoming one of the most useful renewable energy sources.

Solar energy companies

Renewable solar energy is the energy available in the form of heat and light from the sun. To be utilized for a variety of applications, solar energy must be harnessed in a proper manner. Solar power companies are working to do just that. The solar power companies are responsible for making solar energy available to consumers for end use.

Over the past few years’ solar energy as an alternative energy resource gas gained wide acceptance and so the number of solar energy companies is rapidly increasing all over the world. There are many reasons for this significant growth. One reason is that because solar energy is a renewable energy source, it can continue to meet the energy demands of the world for a long time. This energy is also available in abundance and will be available for as long as the sun keeps shining.

Another reason for the rapid increase in the number of solar energy companies is the fact that the reserves of oil that are used to fulfill the current energy requirements are depleting with each passing day. An alternative energy resource is therefore required to replace oil. This alternative energy source is the solar energy.

Solar energy is also being harnessed and used by solar energy companies because it is an eco friendly source of energy. The use of renewable solar energy does not emit any harmful gases into the atmosphere and therefore does not adversely affect the environment.

Solar energy companies are working to provide a cleaner and greener world by the use of solar energy.

Storage of solar energy

Solar energy is a renewable energy source that can be obtained from the sun. Sufficient sunlight must be ensured so that solar energy can be harnessed in a proper and efficient manner. The renewable solar energy can be put to a number of uses. When there is insufficient sunlight or no sunlight at all, solar energy cannot be used as an alternative energy resource. To utilize solar energy effectively it must be available at all times. But during night or on cloudy days, renewable solar energy is not available and so solar energy needs to be stored to meet the energy requirements at any given time. Solar energy can be stored in alternative power stores.

There are several methods available for storing the renewable solar energy. Solar energy can be stored in the form of heat in thermal mass systems. The heat energy can then be used for various domestic purposes. Materials like paraffin wax and Glauber’s salt can also be used to store solar renewable energy at domestically compatible temperatures.

At high temperatures, solar energy can be stored in molten salts. Once solar energy is stored in molten salts, it can be used in conventional heating systems for heating purposes.

When renewable solar energy generates excess electricity, this excess gets stored in off grid solar photovoltaic systems. Solar energy is also stored in hydro electric stores and then is used to generate electricity when there is a high demand of electricity.

Storing solar energy is important for future use but the technology used for this purpose is expensive.
