What is Non-Renewable Energy

Non-renewable energy is energy produced from fuels that cannot be replaced or take a long time to do so. Examples of non-renewable energy are thermoelectric energy and nuclear energy (uranium).

The name of non-renewable energy is given to the energy resource that cannot be regenerated by humans or nature in a time considered suitable for its reuse.

The main and most used non-renewable resources are oil, coal and natural gas, fossil derivatives that will run out one day.

Uranium (nuclear energy) is also another example among non-renewable energies , even cheaper than fossil fuel, but its handling and use requires great care, as it presents a great risk to human beings, since it can cause contamination and lead to various diseases and can be lethal.

What is Non-Renewable Energy

It is famous the case of the nuclear disaster that occurred in Chernobyl, Ukraine (then under the jurisdiction of the Soviet Union), in 1986, which made the site and surroundings useless for healthy housing for at least a century, in addition to reflecting on health until even those born years after the accident.

Advantages and Disadvantages of Non-Renewable Energy

Non-renewable energies are the most used today, but they have advantages and disadvantages . Being pros:

Familiarity: they have been used for a long time and therefore human beings already know how to deal with them and build the necessary infrastructure for their use.

Creation of jobs and possibility of careers in the area.

High energy efficiency and cheaper cost than renewable energies.

These are points against:

The main fact is that they are not renewable, that is, one day they will become extinct.

They are more polluting and therefore are also known as a type of “dirty energy”.

They cause major impacts and serious environmental interference, worsen the greenhouse effect, release harmful gases into the atmosphere, such as carbon dioxide, and can cause nuclear accidents.

Renewable energy

In renewable energy , natural fuels are used that do not run out, so they are better options for smaller impacts on the environment. Examples of renewable energy: solar, wind, hydroelectric and biomass.

Despite their great advantage, they are resources with higher costs, which explains their use in countries with greater development and greater economic power. China leads the ranking of countries that invest the most in renewable energy in the world.

On the other hand, for the same economic reason, poorer and developing countries end up opting for non-renewable energy .
