Examples of Renewable Resources – Top 6

Spread the love

Wanna know what are the top 6 examples of renewable resources? If yes, then you are at the right place at the very right time. Fundamentally speaking, there are only two types of energy resources. These are renewable resources and nonrenewable resources. And, from the heading of this article, you can easily guess that today we are only going to discuss different types of renewable energy resources.

By definition, renewable resources are those that are sustainable sources of energy, meaning, something that can’t track out or is unending. In other words, renewable resources are the ones that are replenished or restored by nature over a period of time.

Some of the advantages of renewable resources are: They are abundant in nature, clean, sustainable, natural, eco-friendly, green, and, so on. Some of the disadvantages are: They are not efficient, require large installation cost, sometimes they are not reliable, etc.

 

Examples of Renewable Resources – Top 6

No wonder there can be so many forms of renewable energy. Out of all, I will be discussing with you the top 6 examples of renewable energy resources that we see in our day-to-day life. Let’s dive right in…!!!

  • Solar Energy – Energy of Sun
  • Wind Energy – Energy of Wind
  • Bio Energy – Energy of Biomass
  • Geothermal Energy – Energy of Earth
  • Tidal Energy – Energy of Gravity
  • Hydro Energy – Energy of Water

The very first one in my list of top 6 examples of renewable resources is solar energy. By definition, solar energy is nothing but the energy that we get from the sun in the form of heat or radiation.

In the current world scenario, around 2% of the world’s electricity need is being generated by solar power. Therefore, in order to reduce our dependence on fossil fuels (non-renewable), what we need to do is to switch to solar power.

Advantages of Solar Energy

There can be so many advantages of solar energy. Here is a list of some of them:

  • Solar energy can be reused by storing in solar batteries
  • Renewable and clean source of energy
  • Reduces electricity bill
  • Requires less maintenance

  • Threat to wildlife, etc.

Uses of Wind Energy

There can be so many uses of wind energy in real life. Here is a list of some of them:

  • Electricity generation
  • Windmill for milling grain
  • Sailing
  • Windmill to cut woods
  • Pumping water
  • Windsurfing, etc.

 

Bio Energy – Energy of Biomass

Bioenergy is the energy we extract from biomass. Well, what is biomass anyway? Biomass is an organic material that comes from plants and animals. In fact, bioenergy that we get from biomass is nothing but the chemical energy stored from the sun.

Therefore, one can also say that bioenergy is also a form of solar energy. Not to mention, as per the available data, around 2% of the world’s electricity is being generated by biofuel.

 

Advantages of Bio Energy

There can be so many advantages of Bio-Energy. Here is a list of some of them:

  • Biomass is degradable
  • Environment friendly
  • Renewable and Clean Source of Energy
  • Provides better air quality
  • Support rural economy
  • Provides stability in Energy Sector, etc.

Disadvantages of Bio Energy

There are some disadvantages of bioenergy. Here is a list of some of them:

  • Deforestation
  • Low Efficiency
  • Hight cost as compared to other renewable resources
  • Threat to wildlife
  • Not completely clean
  • Some biomass are seasonal, etc.

Uses of Bio Energy

There can be so many uses of bioenergy in real life. Here is a list of some of them:

  • Electricity generation
  • Biodiesel for transportation
  • Cooking food
  • Industrial applications, etc.

 

Geothermal Energy – Energy of Earth

The very next one on my list of renewable energy resources is geothermal energy. By definition, geothermal energy is the energy of the earth’s core that we get in the form of heat. In fact, the word geothermal itself defines its essence.

The word geothermal is derived from two Greek words i.e Geo meaning Earth and Thermal meaning Heat. When combined, what we get is the earth’s heat. Not to mention, as per the available data, less than 1% of the world’s electricity is being generated by geothermal.

Advantages of Geothermal Energy

There can be so many advantages of Geothermal Energy. Here is a list of some of them:

  • Renewable Source of Energy
  • Geothermal Energy is Highly Reliable
  • Geothermal Energy protects Environment
  • No Fuel Required

Out of all, Tidal Energy is one of the largest untapped renewable sources of energy. By definition, tidal energy is the energy that we harness by converting the energy of low and high tides to generate electricity or for doing some kind of mechanical work.

Obviously, you would be thinking about why I wrote Tidal Energy – Energy of Gravity. Okay, let me explain it to you. The gravitational pull between the earth and the moon is solely responsible for the occurrence of low as well as high tide. Well, if you don’t believe me, go check yourself. During the night, the sea level is up (High Tide) due to the presence of the moon in the sky.

Similarly, during the daytime, the sea level is down (Low Tide) due to the absence of a moon in the sky. Not to mention, as per the available data, less than 1% of the world’s electricity is being generated by tidal energy.

 

Advantages of Tidal Energy

There can be so many advantages of Tidal Energy. Here is a list of some of them:

  • Renewable Source of Energy
  • Tidal Energy is Highly Reliable
  • Predictable
  • Inexhaustible
  • Low Production and Maintenance Cost
  • Compatible for all climates, etc.

Disadvantages of Tidal Energy

There are some disadvantages of tidal energy. Here is a list of some of them:

  • Very high installation cost
  • Threat to marine life
  • Still in its development phase, etc.

Uses of Tidal Energy

There can be so many uses of tidal energy in real life. Here is a list of some of them:

One of the most commercially viable uses of renewable resources is hydro energy. By definition, hydro energy is the gravitational potential energy of water stored in a dam that we use to generate electricity or for doing some kind of mechanical work.

The energy of the water is generated by constructing a dam across the river flowing upstream to downstream. WHY? Because in order to create a water head (pressure), a dam has to be built upstream of the river.

Not to mention, as per the available data, around 16% of the world’s electricity is being generated by hydro energy. People’s Republic of China’s Three Gorges Dam is the world’s largest hydroelectric facility.

Advantages of Hydro Energy

I am a mechanical engineer by profession. Just because of my love for fundamental physics, I switched my career, and therefore I did my postgraduate degree in physics. Right now I am a loner (as ever) and a Physics blogger too. My sole future goal is to do a Ph.D. in theoretical physics, especially in the field of cosmology. Because in my view, every aspect of physics comes within the range of cosmology. And I love traveling, especially the Sole one.
