Natural Resources include both Renewable energy and Nonrenewable Energy UGC NET Notes
Energy resources are those that can be used for energy production. Natural resources include all those resources which are provided by nature and not anything that is man made. Natural resources can be both exhaustible and non-exhaustible that provide energy for several purposes. There are two sources of energy received from natural resources which are- renewable and non-renewable resources. We will look into these two types of resources below to get a deeper understanding of it and know the differences.
Types of Natural Resources
Natural resources divided into two types, which are : renewable resources and non-renewable resources.
• 1) Renewable Resources
Renewable resources are natural resources which are inexhaustible meaning it does not exhaust no matter how much is the consumption. Renewable resources are sustainable in nature and easily available as it can be naturally replenished. Renewable resources do not cause pollution to the environment and does not get affected by various human activities.
The examples of renewable sources are sun, water, sand, air, soil, wind energy, solar energy, tidal energy, geothermal energy, and hydropower.
• 2) Non-renewable Resources
Non-renewable resources are natural resources which are exhaustible, i.e., they are available in limited quantity and cannot be easily replenished. These resources get exhausted as it is consumed and takes millions of years to be replaced. Exhaustible resources are found on deep surface of the earth. The extraction of these resources causes pollution to the environment and are affected by human activities. As exhaustible sources are not sustainable it should be used wisely keeping the future generation in mind.
Examples of non-renewable resources are coal, oils, and natural gas.
Types of Natural Sources of Energy
The sources of energy provided by natural resources are also of two types, they are-conventional sources of energy and non-conventional sources of energy.
• 1) Conventional Sources of Energy
Conventional sources are exhaustible in nature. They are harmful for the environment as it produces dust and smoke. These sources are costly for maintaining, storing, and transmitting.
Examples of conventional sources of energy are petroleum. coal, natural gas, and water power:
• 2) Non-conventional Sources of Energy
Non-conventional sources are inexhaustible in nature. These sources do not cause environmental pollution. They are less expensive than conventional sources of energy and can be maintained easily.
Examples of non-conventional sources of energy are solar power, geothermal power, tidal power, wind power, and biogas.
Through this chapter we have understood the concept and differences between renewable and non-renewable resources. Both resources are necessary to live life and are equally important for survival of human beings. While some natural resources can be used without much thought, others have to be used thoughtfully as it cannot be replenished quickly and this chapter has provided information on that. The availability of these sources is what makes the planet and life of living beings.
