Every atom and electron in this world is full of energy-negative or positive and contributes in one way or the other in maintaining the energy balance in the universe. On earth we come across three major types or energy resources: Perpetual, Renewable and Non-Renewable. Examples of Perpetual energy resources are wind and sunlight which remain constant despite of unlimited use. Renewable resources are energy providers which can be replenished again and again by making use of physical and biogeochemical cycles. Non-renewable resources cannot be replenished. A good example is fossil fuels.

What are the different types of renewable resources?

Broadly speaking renewable resources can be classified as organic renewable resources and non-organic renewable resources. Plant and animal species are the examples of organic renewable resources whereas gases like oxygen and water are the examples of non-organic renewable resources. Birds or animals getting extinct have now become a regular feature. Although some species have vanished from the earth’s surface due to natural calamities, most of them have become extinct due to excessive hunting and poaching.

Renewable resources are those resources which replenish themselves more rapidly than they are consumed. In the recent times, technological advancements have sparked a hope that almost every resource consumed by humans can be replenished if they are given ample time or certain ways are developed to make the replenishing procedure faster. Off course with some energy resources like coal, oil etc. this is not possible as they take at least hundreds of years to replenish. The most prominent examples of renewable resources are Water and Solar power.

How is water recycled back to nature?

Water in natural conditions is cycled back to nature by rain, evaporation and other similar ways. It also helps to produce energy through dams and various types of aqueducts. The flowing water is used to harness energy. But there are times when water cannot be renewed. Pollution, cultivation, grazing, urban sprawl, irrigation, fishing, hunting, habitat destruction and deforestation has reduced the speed of replenishing of water as a resource due to which nowadays, many times water has to be cleaned or recycled so that it becomes good enough for regular use.

Which is the biggest renewable resource?

Sun rise everyday and gives light throughout the day. The solar energy if harnessed can illuminate the whole world and scientists are trying hard to convert most of this energy received into solar energy. Many new techniques are being used to derive maximum benefit from this Sun rays, as these are the biggest renewable energy resources. If mankind succeeds in generating ample amount of energy from Sun, then we won’t be dependent upon the earth for energy resources.

Is wind a renewable resource?

The latest to add to the list of renewable resources is the wind energy. Wind farming has taken off as the next solution for creating renewable energy, but it is still in need of more improvisation and research. But even now many homes and streets are being lighted in some countries by using wind energy.

Why are renewable resources important?

Nowadays, the effort is more to find ways of recycling and renewing things. Even the paper is being recycled so as to minimize the demand for wood. Whenever the trees are cut off, saplings are planted so as to cover the loss. All these efforts are contributing to replenish the lost resources. Go Green is the ‘mantra’ which is gaining popularity everywhere and from cardboard, paper, farming bi-products, scrap metal, wood and even some oils all are being recycled today. Bio-materials are rapidly gaining attention for their reliability as renewable resource and better technological advancements are bringing more improvised techniques for recycling and renewing these resources.

Why? because, the growing demand for energy resources has put a huge pressure on mankind as the existing resources will be exhausted in the near future and we would be left without any proper energy resource. Renewable resources are the key to our future energy needs and hence all different possibilites are being tried to harness energy from the existing resources available.
