Concepts and meanings of renewable resources

1. Definition of renewable resources

A renewable resource is a natural resource that can be restored by natural processes at a speed exceeding consumption by humans. Solar radiation, tidal, wind and hydroelectric power are perpetual resources that do not run the risk of run out long-term. Renewable resources also include materials such as wood, paper, leather, etc. If they are harvested in a sustainable manner.
Some renewable resources such as geothermal power, fresh water, wood and biomass should be handled carefully to avoid exceeding the world regenerative capacity of the same. It is necessary to estimate the capacity of renewal (sustainability) of such resources.
Products such as gasoline, coal, natural gas, diesel and other products derived from fossil fuels are not renewable or do not present sustainability. They differ from renewable resources because they can have a sustainable productivity; i.e. they are inexhaustible.


2 Concept of renewable resources

A renewable resource is a natural resource that can be restored by natural processes at a rate similar to or greater than the consumption by humans. Solar radiation, tidal, wind and hydroelectric power are perpetual resources that do not run the risk of run out long-term. Renewable resources also include materials such as wood, paper, leather, etc. If they are harvested in a sustainable manner.

List of important renewable resources
-Biomass: forests and timber, agricultural products.

3. What is Renewable resources

Referred to as resources to the set of capabilities and elements (both natural and as produced by man), which you can use to produce goods or services or have an intrinsic value without the need to be modified, and they are scarce in relation to your current or potential demand.
Renewable resources are those resources whose existence is not exhausted with their use, since they return to its original state or are regenerated at one rate greater than the rate with which renewable resources are diminished by its use. This means that certain renewable resources can stop being so if your utilization rate is so high that you avoid its renewal. Within this category of renewable resources we find water and biomass. Some renewable resources are classified as perpetual resources, due to by more intense to be its use, its depletion is not possible. Within this category of renewable resources are hydroelectric power, solar radiation, wind and waves.

Energy and renewable resources

With regard to energy, as well as the production of electricity using solar radiation directly much of renewable resources with ability to provide energy comes from solar energy (99.9% of the energy on earth comes from solar energy). For example, hydraulic energy exists because the heat from the Sun and the winds carry water from low-lying areas to higher biomass that can be used as a biofuel exists due to the process of photosynthesis which is an efficient way of using solar energy, energy from wind also exists since the energy from the Sun heats the regions in a different way.
Although the total energy available is enormous, the challenge is to transform the energy available in usable energy by man. The transformation of one type of energy into another, for example the transformation of hydraulic energy into electrical energy, or the energy use without transforming it, for example to heat water with sunlight, will be more or less effective depending on the technology available. New scientific and technological advances make the loss by the transformation of one type of energy into another each time smaller.
Then let's see each of these potential renewable sources of energy: hydropower, solar energy, wind energy and energy from biomass.
Hydraulic energy is mainly mechanical energy from water that descends from Highland to lowland areas attracted by the force of gravity. The mechanical energy contained in the water movement has been exploited by men since ancient times by water mills, which used mechanical energy directly. Currently this renewable energy building dams and hydroelectric power plants to transform this energy into electrical energy can be exploited. Hydropower is a renewable resource because after use, the water returns towards the Highlands (the water cycle).
Solar radiation contains energy that can be transformed into heat (thermal energy) or electricity. Primary solar energy is a renewable resource.

Wind energy can be transformed into electrical energy using wind turbines

Biomass contains energy since photosynthesis was accumulating solar energy in it. Through combustion, the energy contained in biomass can transform into caloric energy into electrical energy or it can be processed for processing into biofuel-capable of being used in automobiles and other means of transport. Biomass is a renewable resource if your utilization rate is less than or equal to its rate of regeneration.
The recent growth of the biofuels collaborated to the rise in the price of food around the world, threatening the food security of many countries, in particular those low-income countries that are net importers of food.

Water as a renewable resource

The clean, fresh water is a renewable resource because of the water cycle, but this does not mean that it is an unlimited resource. The growth of the population and pollution or destruction of natural sources of clean water can endanger the provision of water.
For example, if it draws water from an aquifer at one rate greater than their renewal rate, that aquifer water stops being a renewable resource. The same thing would happen if agriculture in an elevated area does not allow water to enter the groundwater.

Agriculture products such as renewable resources

Since plants have the ability to grow without depleting the soil, are renewable resources provided that your use complies with this requirement, i.e. that their rate of consumption does not obstruct your future feedback. A concept more strictly takes into account throughout the production process, by which the agriculture products (food, biofuel, raw materials, chemicals, etc.) are considered renewable if in addition to its cultivation, harvesting, logistics, processing and distribution can be considered "sustainable".
Obtained from forests as timber, chemicals and paper can also be renewable resources if they are produced using sustainable techniques.


4. Definition of renewable resources

The renewable resource is a type of natural resource that can be renewed from natural processes and with a much higher speed to the extent that humans consume them, i.e., serenuevan so quickly that they are not exhausted and then men can make use of them always.
It should be noted that a natural resource is the one that offers us the nature and human as such not presents any kind of intervention. Natural resources are extensively assessed for this reason and because certainly contribute to the welfare and development of different products necessary for life.
Among the types of renewable resources are: water, solar, wind, tidal and hydropower.
Somehow we could qualify them as eternal since it is very difficult that they run out with the passing of time. However, there also are other renewable resources if it is produced in a way also regulate in time we will have with them, such is the case of wood, paper, leather, among others.
The energy source that most rampant in our planet is without doubt the solar.
For its part, wind energy, or the wind, also abounds in the world and by cleaning that supposed is a huge help when it comes to lessen the negative effects caused by fumes of greenhouses, so harmful to our natural environment. However, find you a disadvantage and it is intermittent which we cannot rely strictly of it.
In the case of hydropower, is made present thanks to the movement that occurs in oceans and other waters. If a few turbines are placed him, it is extremely useful to produce energy of electric type.
Water, likewise, is a renewable resource when use is operated within a deresponsabilidad framework, i.e. to control its transit, processing and circulation.
The main characteristic that hold these resources and that is that will differentiate them opposite resources, which are non-renewable resources is its sustainability, i.e., they can be produced in a sustainable way through time and not exhausted, something that of course not the case with non-renewable that yes they deplete with use.
Within the Group of non-renewable we find gasoline, diesel, coal and natural gas.
