Examples Of Inexhaustible Resources & Their Uses

Inexhaustible natural resources , also called renewable , are those that are not spent, that is, they can be used indefinitely. For example: solar energy, wind energy.

They differ from exhaustible or non-renewable resources , which are those that either cannot be produced again, or are produced at a much slower rate than they are consumed (for example wood). Some examples of exhaustible resources are oil , some metals , and natural gas.

Currently, most of the energy we consume globally comes from exhaustible resources. We use that energy to obtain electricity , heating, in industry and  transportation . Although these energy sources have the advantages of being constant in space and time, they have the disadvantage not only that they will run out in the medium term but also that they produce a large amount of polluting gases . For this reason, efforts are being made to replace them with inexhaustible resources.

Characteristics of inexhaustible resources

  • They don’t run out . For example: wind, or they are renewable, that is, they can be produced at a faster rate than they are consumed, for example some crops, which are used to generate fuels such as biodiesel.
  • Inconstancy of intensity . They are inconstant in both time and space, for example, we cannot have solar energy available all the time, since it remains present during the night or when the sky is overcast. With respect to space, there are regions in which wind energy can be used, because the winds are intense, while in others they cannot.
  • Dispersed intensity . The energy intensity in general must be obtained from a very large area, for example it is necessary to use a large number of solar panels to obtain the necessary energy. That is to say, the energy per square meter is low, so obtaining it is expensive. However, it is independent, since, unlike, for example, electrical energy , it does not need to be linked to a network.
  • Clean energies . Unlike fossil fuels , they do not emit carbon dioxide into the atmosphere.

Examples of inexhaustible resources

  1. Solar energy . The sun emits radiation of which our planet receives such a large amount that in just one hour it is enough to satisfy the energy needs of the entire world for a year. The technology that uses this energy is photovoltaic single energy. A device called a photovoltaic cell is used. To a lesser extent, solar thermoelectric energy is also used, which uses mirrors to concentrate sunlight on a small surface, converting solar energy into heat , which drives a heat engine that generates electricity.
  2. Wind power . The energy that comes from the wind is used through the rotation of wind turbines. The wind turbines that we currently see in the shape of large white windmills with three thin blades are called wind turbines. They were created in 1980 in Denmark.
  3. Hydroelectric power . It uses the kinetic and potential energy of moving water, that is, rivers, waterfalls and oceans. The most common way to obtain hydroelectric energy is hydroelectric plants. Although it has the advantage of not emitting polluting substances and being an inexhaustible resource, it has a great environmental impact due to the flooding produced by hydroelectric plants.
  4. Geothermal energy . Inside, our planet has heat, which can be used to generate energy. The temperature increases with depth. Although the earth is cold on the surface, we can observe the effects of the earth’s heat in geysers, hot springs, and volcanic eruptions.
  5. Biofuels . It is not a specifically inexhaustible source but more exactly renewable, that is, it can be produced at a much faster rate than its consumption. Alcohols or oils can be created from crops such as corn, sugar cane, sunflower or millet to be used as fuel. Its carbon dioxide emission is significantly lower than that emitted by fossil fuels such as oil.

Uses Of inexhaustible resources

Inexhaustible resources, such as solar and wind energy, are used for clean electricity generation, reducing reliance on fossil fuels and mitigating climate change.

Additionally, renewable resources like water and biomass sustain agriculture, provide drinking water, and support various industries, promoting sustainability and resilience.
