Are you looking for the Renewable and Nonrenewable Energy? So today we will study the Definition, Resources, and Types, Example, Advantages, Disadvantages, Differences, and PDF. Here you will get the articles of Mechanical Engineering in brief with some key points and you will get to know an enormous amount of knowledge from It. So If you find this articles helpful, please let us know in the comment box, either if any correction required too, also let us know in the comment box.

Renewable and Nonrenewable Energy:


Renewable Energy:

The is defines as the sources of energy which are produced continuously in nature and are essentially inexhaustible at least in the time frame of human societies.

These energy sources replenished themselves naturally in a relatively short time and therefore will always be available.

Non-renewable Energy:

The Nonrenewable Energy resources are defined as the energy resources which have been accumulated over the ages and not quickly replenishable when they are exhausted.

Renewable and Nonrenewable Energy

Resources / Types / Example of Renewable sources of energy:

The example is:

Direct Solar Energy

Wind Energy

Tidal Energy

Hydel Energy

Ocean Thermal Energy


Geothermal Energy



fuel cells

Solid waste


Resources / Types / Example of Non-renewable sources of energy:

The example is:

Fossil fuels

Nuclear fuels

Heat Traps

Advantages, Disadvantages of Renewable sources of energy:


This energy source is stable.

Multiple forms of energy sources exit in nature.

These are safe, abundant, and clean to use when compared to fossil fuels which are non-renewable energy.

This is low maintenance energy sources.

This does not harm the planet.


Some energy sources require a huge place to construct the dam like a hydel power plant.

This is not complete pollution-free sources of energy. Pollution still generated(Very less amount).  A resource like biomass still burns waste products and puts pollution into the atmosphere. This includes carbon and methane, which are classified as greenhouse gases.

Requires storage capabilities.

Location-specific sources type of energy.

Not every type of renewable sources of energy is commercially viable.

Unreliable weather can affect energy supply.

Advantages, Disadvantages of Non-Renewable sources of energy:


This Source of energy is affordable. For instance diesel and oil.

It is easily accessible and more compatible.

This source of energy is easy to store.

Energy is cost-effective and easier to produce and use.


The main disadvantages are:

It cannot be replaced once their energy source is used.

The by-products of non-renewable energy cause environmental damages.

Also increases greenhouses gases which affect the planet.

Differences between Renewable and Nonrenewable sources of energy:

Sl. No Renewable Energy Sources Non-renewable Energy sources
1. This energy sources can be replenished with a short period of time. Whereas, This energy sources cannot be replenished with a short period of time.
2. Sources like Solar energy. Wind energy is continuously available and do not deteriorate environmental health and also human health. This sources type contributes to generating greenhouse gases that cause Global warming, a negative effect on the environment.
3. Renewable sources involve high investment though it is available cheaply. It quite cheap compared to renewable.
4. Due to the intermittent nature of availability of energy sources like solar, wind and Tidal continuous supply of energy is not possible Here the continous supply of energy is possible.
5. Few renewable energy conversion systems can be often built close to the site where energy is required. This minimizes transmission costs. Transmission costs are generally high.

The other 5 points are:

6. Energy sources such as wind energy, Tidal energy are available in the only selected geographical region in the world. This energy source is less dependent on the geographical regions and normally available everywhere.
7. Not dependent on foreign suppliers. But this one is may depend on foreign suppliers like coal, petroleum and more.
8. This sources can be used again and again. But Non-renewable cannot be used again and again. One day it will be exhausted.
9. This is pollution free sources of energy. This is not a pollution free source of energy.
10. Example: Solar, wind, Tidal energy. Example: Fossil fuel, coal.
