The inexhaustible solar energy

The sun is a star that has been providing solar energy to the earth since the last 4 billion years

. The amount of solar energy that is received by the earth is incredible. The amount of solar energy received by earth in one minute is equivalent to its requirement of a year. All the fossil fuels that are currently present in the earth can give the amount of energy equivalent to the solar energy that is received by the earth in just 3 days. These figures are hard to believe but this is absolutely true. This article is all about the inexhaustible solar energy.

Solar energy is an inexhaustible and renewable form of energy that has been exploited since long time by human beings using a number of tools and technologies. Out of all the available renewable source of energies, solar energy is the most available one on the earth. Only a small fraction of the total energy available is used for different purposes. The sun is a consistent source of power that will be with us every time. Unlike fossil fuels that release carcinogens, green house gases, carbon-dioxide and other poisonous gases in environment, solar cells do not release any of these venomous gases in the air. Thus it is environmentally friendly that does not pollute the air.

Using the solar power, electricity can be generated that completely depends upon the photovoltaic cells and heat engines. There is a wide range of applications of solar power. Some of the major applications include space cooling and heating through its architecture, solar cooking, and potable water by distillation and disinfection, day lightning, hot water and the high temperature process heat for several industrial uses. The simplest method of extracting the solar energy is the implementation of solar panels.

Solar electricity is cheaper as compared to other sources of electricity. There is a start up cost but after that it does not require any more investments for the production of electricity. Once break even point is reached, everything after that is profit. A number of solar panel systems are available. Some of them can be expensive and some can be very cheap. This means that everyone has the entry point to get into solar panels.

By these data's, we can see that solar energy is inexhaustible and it can easily quench the requirement of electricity.
