Determining the meaning of non-renewable energy is our purpose. But for this it is essential that we previously determine the etymological origin of the words that make up that term:
• Energy. It comes from the Latin "energy", which in turn comes from the Greek word "energeia." The latter was made up of three parts: the prefix "en"; the noun "ergon", which is equal to "work"; and the suffix "-eia", which was used to express a quality.
• Renewable. It also emanates from Latin as evidenced by the fact that it is the result of the sum of three Latin components: the prefix "re-", which is synonymous with "repetition"; the word "novum", which can be translated as "new"; and the suffix "-able", which is equivalent to "can".

Energy is the ability to transform or move something . The concept is often used in reference to a natural resource with the associated elements that allow an industrial use of it.

Renewable , meanwhile, refers to what can be renewed (that is, it can be returned to its first state or replaced). Applied to energy, this notion is linked to the possibility of renovation or restoration through a natural process .

The non-renewable energy therefore it is the type of energy obtained from a limited natural resource, so once it is depleted, it cannot be substituted . As there is no viable production or extraction system, when the reserves of resources that allow generating non-renewable energy are depleted, it will cease to exist.

Non-renewable energies come from fossil fuels or nuclear fuels . In the first group we can find the Petroleum , he carbon and the natural gas . These fuels are easy to extract, but their reserves can be depleted in the short or medium term. Once there are no more oil reserves, for example, the human being will not be able to create new ones.

In addition, it should be stressed that fossil fuels have other equally important advantages such as, for example, that they are cheap or have a long time availability. However, they have the great disadvantage that they emit pollutant gases that are harmful both to the atmosphere itself and to the human being.

Between the nuclear fuels On the other hand, elements such as plutonium or the uranium . These are limited and, therefore, non-renewable fuels.

In the case of nuclear fuels we could highlight as main advantages that produce abundant energy and that do not emit gases that can create what is known as the greenhouse effect. However, they also have their damages or disadvantages as they are that, in case of accident, they can cause a serious environmental or personal catastrophe and that are harmful for centuries. Specifically, a good example of this are the Chernobyl (1986) or Fukushima (2011) catastrophes.

The renewable energy Instead, they come from sources that are virtually inexhaustible thanks to their ability to regenerate naturally or to the large amount of energy they have. The wind power It is an example of renewable energy, since the wind is inexhaustible.
