Renewable resources are things like water, soil, air, forests and animals, to put it simply. A commonly accepted definition is that a natural resource is a renewable resource if it is replaced by natural processes at a rate comparable or faster than its rate of consumption by humans. Solar radiation, tides, winds and hydroelectricity are in no danger of a lack of long-term availability, so it is reasonable to describe them as renewable. Renewable resources may also be used describe materials such as wood, paper, and leather, if harvesting is performed in a sustainable manner. In other words wood is renewable, but only if more forests are being planted to replace the trees that are being felled.
So. we might say that renewable resources are those which can be replenished over time by some natural process, including farming. Such resources have the ability to be renewed over a short period of time.
We suggest that you watch our video below, which explains and gives examples of renewable resources:

Geothermal energy is often classed as renewable and as it is provided by the heat of the Earth, and comes from under the ground it is in reality also an inexhaustible energy source.
Renewable resources are an important aspect of sustainability. According to the U.S. Energy Information Administration, the most frequently used renewable resources are biomass, water, geothermal, wind and solar. Unlike using fossil fuels, we can regenerate or replenish these resources. Although biomass in the form of wood once supplied 90 percent of U.S. energy needs, all renewable energy sources combined supplied only about 8 percent of in 2009.
Let’s think about the gasoline we use in cars. Gasoline is a non-renewable resource, which means that we’re going to run out of it! Someday, there won’t be any gasoline left. We’ll have to think of something else to use to run our cars!
Now let’s think about trees and wood. Wood is a renewable resource. So long as we take good care of the forests, we will never run out of wood!
Renewable resources are energy sources that our planet and our living organisms use, but that can be recreated by natural processes once theyâ€™re used up. In this case, the intentional planting of new trees, for example, would still be considered â€œrenewable,â€ even though human intervention made it possible. Some renewable resources take long periods of time to regenerate, like those trees, while others take literally no time, like sunlight or wind.
Global attention has been drawn rcently to the need to switch to a higher reliance on renewable resources than our existing practices of making use of sources like fossil fuels. Renewable resources are in theory unrestricted, and the majority of the types that are in use are far less contaminating than nonrenewable fuel sources.
A renewable resource is one that replaces itself normally at a rate equal to or greater than human usage. The term typically refers to renewable energies, which are self-reliant in time. There are five major kinds of renewable resources, solar, wind, hydropower, geothermal and biomass. Lots of nations today are enhancing their use of renewable energies to change fossil fuels, such as coal and petroleum, which take thousands and often countless years to change themselves, making them non-renewable resources.
Solar power is the conversion of sunshine into usable energy. It’s done using solar panels which convert the sun’s light and radiation into electrical power. Solar power has exceptionally high capacity since it is incredibly available. According to the science journal “Nature,” the sun provides Earth with more energy in a single hour than human beings use in a year.
Fossil Fuels: coal, oil, gas and soil, rocks, minerals. As soon as they have been removed from a mine or washed away it takes a VERY long time for them to form.

We have counted on fossil fuels for our energy requires because, traditionally, these fuels have actually been relatively affordable, and lucrative for developers. With rising fuel rates, concerns about environmental effect and growing political issues about oil providers, renewable resource is gaining in importance.
Renewable resources are natural sources that can not be reduced. Examples consist of solar, wind, hydroelectric, biomass and geothermal. Fossil fuels like coal, oil and even clean-burning gas do not exist in limitless supply. Someday they will certainly be gone. In extra to endless accessibility, renewable resources produce less ecological effect, specifically pollution.
In the world we come across 3 major types or energy resources: Perpetual, Renewable and Non-Renewable. Examples of Perpetual energy resources are wind and sunshine which continue to be consistent despite of unlimited use. Renewable resources are energy carriers which can be replenished once more and once again by utilizing physical and biogeochemical cycles. Non-renewable resources can not be renewed. A good example is nonrenewable fuel sources.
Broadly speaking renewable resources can be classified as organic renewable resources and non-organic renewable resources. Plant and animal species are the examples of natural renewable resources whereas gases like oxygen and water are the examples of non-organic renewable resources.
Examples of renewable resources are fresh water, fish, and soil. Non-renewable resources such as oil and minerals are irreplaceable, and they do not successfully regenerate once they are consumed.
Renewable energy refers to power created by a renewable source. When the energy is generated, the resource is not diminished or used up. They are normally replenished, and can either be handled so that they last for life, or their supply is so enormous human beings can never ever meaningfully deplete them. Unlike fossil fuels, renewable resource sources do not launch co2 as a by-product into the environment. As the amount of nonrenewable fuel source resources in the world reduces, it is ending up being increasingly important to discover and use alternative fuels.
In the US, Alternative Energy is used and in basic it suggests the like renewable, suggests any thing other than deriving energy through Fossil Fuel combustion. Alternative energy is also a natural resource ends up being a renewable resource when it is changed by natural procedures at a rate which is much faster than its usage rate by human beings. Solar radiation, tides, winds and hydroelectricity are the sources which are of long-lasting accessibility. Renewable resources might consist of mean products like wood, paper, and leather, if their harvesting is carried out in a sustainable manner.
Some natural renewable resources such as geothermal power, fresh water, timber, and biomass must be used with care to stay clear of exceeding the capability to replenish them. A life process supplies an organized means of computing renewability.
Potentially, renewable natural resources can sustain collecting forever. However, to achieve a condition of sustainable usage, the rate of harvesting must be smaller than the rate of renewal of the resource. For example, flowing water can be sustainably used to produce hydroelectricity or for irrigation, as long as the usage does not surpass the capacity of the landscape to yield water. Likewise, biological natural resources such as trees and hunted fish, waterfowl, and deer can be sustainably gathered to yield valuable items, as long as the rate of cropping does not go beyond the renewal of the resource.
So, to sum up, we will just state that a renewable resource is a natural resource that can replaced through biological or other natural procedures and replenished after some time. They belong to natural environment but they are jeopardized by industrial developments and over population. Solar radiation, biomass, tides, geothermal, and winds are examples of renewable resources.
