SI system
Except in cases where it is inappropriate, the International System of Measurement Units (SI) will always be used. If it is convenient for a better understanding of the subject matter, after the magnitude expressed in SI, the value and units in another system can be added in parentheses. On the other hand, it is convenient to use no more than five significant figures. Note that all SI quantities must be 1 space apart from numerical values ​​(examples: 450 kW, 10%, 30°C). Additionally, it will be ensured that the numerical values ​​and the corresponding magnitudes or the symbols listed above must appear on the same line.
Equation editor
Mathematical formulas and equations should be placed one space apart from adjacent paragraphs, centered at the width of the margin, and numbered consecutively to their right. These equations must always be stated before putting them (as is done with figures and tables, never put expression (1)). Example: equation (1). After the equations, a description of the variables (the variables of the equation, when they are announced in the text is done in Word) that compose it will be placed. Using the equation editor built into Microsoft Word 2013 or 2016 is not recommended. Use of the MathType equation editor is recommended. Example in the equation:


Where Btotal: Number of workers x salary/days; CUP (peso, national currency of Cuba)
P_x: Quantity of materials used for their respective costs; cup
The variables within the text must be incorporated in word format and NOT in any equation editor.
The symbology to be used within the equations and within the text must be taken from the character map of the Time New Roman font. All symbology on this map can be used.
The articles are divided into:
1. Primary Partition (Section Title)
2. Second Order Partition (Section Subheadings)
3. Third order partition (Section title)
Invariably the article will consist of:
The introduction should provide the reader with a brief and sufficient overview of the objective of the article and the theoretical framework on which it is based. After the introduction, the development of the article is presented, the following sections must follow an explanatory and clear order of the relevant aspects of the research.
In this section, which may have a different title, the samples or study objects, the experimental installation and its general characteristics relevant to the study must be described.
In this section, which may have a different title, the key results of the research must be presented objectively, without interpretation and in an orderly and logical sequence of the illustrative materials (tables and figures) and the text.
This section shows the real contribution to knowledge, therefore the authors must interpret the results and translate the findings into a practical, conceptual or theoretical meaning; these interpretations should be made in the same logical order in which the results were presented. In addition, they can reflect on the implications of these results, mentioning previous and future research, as well as possible uses of the results and trends on the topic or problem addressed. Potential limitations of the study, such as sample deficiencies, design problems, difficulties in data collection, etc., should be included.
This section should highlight the most important contributions and compare them with previous ones and their limitations, if any, suggesting possible research. Here the current and possible applications must also be proposed, as well as the recommendations that it proposes for the universalization or extension of the published results.
In all cases, repeating what is stated in the summary will be avoided. AND VERY IMPORTANT The first conclusions presented must be those that correspond to the stated objectives.
If necessary, this section should be located after the conclusions. It is recommended that the authors thank those who have allowed, helped and collaborated in obtaining the results referred to in the article. In case it is appropriate to express thanks, it is suggested to use a typical heading such as: “The authors wish to thank…”
References are important to the reader, so each citation must be correct and complete. There is no editorial verification of the correctness of the data (authors, titles, journal, congress, volume, number, pages, date, etc.). Yes there will be about its style and completeness. Therefore, an error in the data of a reference will reduce the authority and value of the article. References should be made in the place of the sentence in which they are applied, and avoiding listing at the end of a paragraph more than 3 or 4 references related to your study and that were not really important in it, such as: [1-2 ; 4; 7; 10; 12]. Articles with fewer than 10 nor more than 25 references will not be accepted, except for bibliographic reviews whose number of references will be approved by the editorial committee for each particular case and all must be cited in the text, as well as all the references cited in the text, should be listed in this section. References must be related to publications and documents that are generally accessible to the public through ordinary channels (books, magazine articles, congress articles, patents, doctoral theses with ISSN, conferences, application notes and accessible technical reports from companies, university departments and research organizations).
The following is a list of sources that should not be included in this section:
— TV shows and newspaper articles.
— Preparation of postgraduate courses or any other related document, such as course manuals of any kind.
— Programs of subjects, careers, teaching guides of any kind.
— Manuals of equipment, instruments, etc.
— Software, software manuals and software sites.
— Reports, unpublished books and monographs.
— Catalogues, brochures and bulletins.
— Unregistered journals and non-scientific journals.
— Standards of companies or other entities not recognized internationally.
— Documents from Internet sites not recognized for their scientific rigor.
— Works from events not recognized internationally.
— Diploma papers that do not have an ISSN or DOI and that are not published in a virtual repository.
— Master's theses, which do not have an ISSN or DOI and which are not published in a virtual repository.
— Doctoral theses that do not have an ISSN and that are not published in a virtual repository.
— Any other type of document that is not accessible by the general public.
• If you want or need to reference the previous sources, you can include them within the text, although their use is not convenient, since the reader does not have access to them.
• Avoid using references that are hard to find.
• Avoid listing related references that were not relevant to the study.
• Use peer-reviewed journal articles published on the internet as essential references.
• All references used in an article must be available to the reader.
• They must have an actuality (last 5 years) of 70%.
• Avoid self-citations, only 10% of author self-citations are allowed.
Even if doctoral theses and papers at scientific events are published on the Internet, use should be moderate. Remember: References are one of the quality indexes of a scientific article.
The criteria for creating bibliographic references (content, form and structure) established by the Energetic Engineering journal, which must be met for the article to be sent for review, is the one established by the Vancouver standard.
If such a reference seems absolutely essential, it may be added to the text in parentheses. In the bibliography, a work that has been accepted for publication can be included, citing the name of the journal, followed by "accepted for publication".
Use as many updated and quality references as possible, mainly those published in the last 5 years and from scientific journals, both national and international. Avoid excessive self-dating.
Any information that does not pertain to your experiment and is not "common knowledge" should be acknowledged by citation.
References should be made in the place of the sentence in which they are applied, and avoiding listing at the end of a paragraph more than 3 or 4 references related to your study and that were not really important in it, such as: [1-2 ; 4; 7; 10; 12].
Articles with less than 10 references and no more than 25 will not be accepted, all must be cited in the text, as well as all the references cited in the text, must appear in this section.
The numerical citation system of the references will be used. This system refers to the citation of the work of origin by means of a number that refers to a list of works cited at the end of the article, so these must be identified with a consecutive number between brackets and grouped at the end of the text in the order of appearance. In the sentences, do not refer to the reference number, "as in [1]", but write it at the end of it, always before the punctuation marks. Multiple references should be listed separated by a hyphen [2-3]. If you wish to mention the name of an author, do so in the context of the sentence, writing the author's first surname and the year of the work consulted in parentheses, for example: "Anglada (1999) defines…"; at the end of the idea expressed by that author, place the number corresponding to that reference [8].
Any reference that does not appear in the Latin alphabet must be transliterated in accordance with international regulations.
The criteria for creating bibliographic references (content, form and structure) established by the Revista Ingeniería Energética, which must be met for the article to be sent for review, is that established by the Vancouver standard.
They will be listed in order of appearance and will comply with:
-At least 70% must belong to the last 5 years.
-At least 70% will be foreign references and scientific journals.
-There must be a correspondence of 70/25/5 in articles of serial publications, books, monographs, manuals and other types, between the references used.
Those works that have been edited by recognized entities will be cited as published in any medium: universities, research centers, international organizations, high-level companies, etc.
The reference to a document on the Internet must show the full URL and the date it was consulted.
For example:
 • The content, form and structure of the Electronic Texts, Databases and Computer Programs, whether they are accessible online, or whether they are on a tangible computer medium (floppy disk, magnetic tape, cd-rom, etc.) must respond to the following model:
   Primary author. Title [media type]. Edition. Secondary author(s). Place of publication: publisher, date of publication, date of update / revision. [Date consulted] (Collection). Normalized number. Availability and access. Notes [1].
 • The content, form and structure of Collaborations in Electronic Texts, Databases and Computer Programs must respond to the following model:
   Main author (of the collaboration). "Title" (of the collaboration). In: Main author (of the source document). Title (of the source document). [Media type]. Edition. Secondary author (of the source document). Place of publication: publisher, date of publication. Numbering and/or location of the collaboration within the source document. Date of update / revision. [Date of consultation]. Normalized number. Availability and access. Notes [3-5].
 • The content, form and structure of Electronic Serial Publications. Complete Series or Entire Copy of a Series must respond to the following model:
   Title [media type]. Edition. Place of publication: publisher, date of publication. [Date consulted] (Collection). Normalized number. Availability and access. Notes [5-6].
 • The content, form and structure of Electronic Serial Publications. Articles and Contributions in serial publications must respond to the following model:
   Main author (of the collaboration). "Title (of the collaboration)". Title (of the serial publication). [Media type]. Edition. Place of publication: Publisher, date of publication. Issue number. Location of the part within the source document. [Date of consultation]. Standardized number Availability and access. Grades. [7-8].
 • The content, form and structure of the Electronic Bulletins, Discussion Lists and Electronic Messages must respond to the following model:
   Author of the message Title of the message. Messaging system title [media type]. Date of the message. Message time. [Date of consultation]. Availability and access [7-8].
The self-citation rate for the Energy Engineering journal will be less than 10%.
Those works that have been published by recognized entities will be cited as published in any digital or printed medium: universities, research centers, international organizations and high-level companies.
Avoid excessive referrals. Only references that are really necessary and directly relevant to the research topic should be cited.
Do not support, by reference, statements that the entire audience knows.
Avoid using as references: theses, abstracts, project reports if the information has not been published in a scientific journal, as well as books that are available to the reader. Preference should be given to recent publications in journals.
How to cite
The brief textual citation, of less than five lines, is inserted within the text between quotation marks, and the corresponding number is placed at the end, after the quotation marks and before the punctuation mark.
“A bibliographic citation is a very abbreviated expression of a bibliographic reference inserted in the text which refers to it and adopts different notations depending on the system or style used (Harvard, AMA, Vancouver). Bibliographic citations are located within the text or at the foot of the pages” (1).
Author citations: “The citations of an author can be made by a number or by integrating the author's name followed by a number in the text. When an author is mentioned in the text, the reference number is placed after the author's name. If the author is not named, the number will appear at the end of the sentence”(2).
Example: Watkins and Marsick (1, 2) provided an integrative model of a learning organization.
Author registration:
• The names of the authors, publishers, etc., must appear as follows: Surname First letter of the name: Santos A.
• If an author is used to using his two surnames, they must be joined with a hyphen: Vilaragut-Llanes M.
• If an author uses two first names (compound names), their initials must be joined: Filgueiras-Sainz de Rozas ML
Reference style
They must be written with Arabic numerals in brackets, example: [23], [1, 5, 12]. If specific parts of a document are cited, the pages can be indicated, example: (2 p. 57), if several consecutive references are cited: [2-6].
Do not support a claim with more than three citations, such as: [2, 4, 7, 10, 12, 15].
The references are written with all their main data, including the normalizing identifier: ISSN and ISBN, or the DOI.
DOI: digital object identifier, known in English as digital object identifier and abbreviated DOI, which is nothing more than a permanent link in the form of an alphanumeric code that uniquely identifies an electronic content. In the format:

DOI directory:

A suffix identifying the publisher
A suffix that identifies the digital object (it has a variable structure, depending on the publisher)


The reference to a document on the Internet must show the full URL and the date it was consulted.

Editorial Policy

The journal is published in accordance with the principles outlined in the Committee on Publication Ethics-COPE. 
We recommend that you read the flowcharts of the Committee on Publication Ethics-COPE for bad practices in article writing, plagiarism, changes of authors, etc.
Copyright Statement
Authors should not include in their articles information taken from other published or unpublished works without proper citation of the source. The author must cite and give the appropriate attribution to those publications that have influenced and determined the nature of the article to be published in order to guide the reader to previous works that help them understand the published work.
If an article is accepted for publication, the author has the right to have it published.
The main author has the right to withdraw their article from the evaluation process at any time without affecting its consideration for future publications.
Rights and Duties of the magazine
When submitting the article, the authors must confirm that the article has not been published in any type of medium before, nor can they have submitted it to another journal simultaneously. In case of having been sent to another journal and not being accepted, they must argue the reasons for the rejection.
The Ingeniería Energética magazine adheres to and promotes respect for the rules of the Spanish languages ​​(as dictated by the Royal Academy of the Spanish Language. RAE), English and Portuguese.
Except in cases where it is inappropriate, use the International System (SI) of units of measure. After the magnitude expressed in the SI can be added, in parentheses, the value and units in another system of units.
Policies regarding the contribution of authors
All authors of a manuscript must have contributed significantly to the development of the research, in all or most of its phases.
To protect the integrity of the authorship of the work, only the professionals who have collaborated in the research or the project and preparation of the article will be listed as co-authors. The main author attests to the fact of having included all the co-authors of the work when submitting the request for publication.
All co-authors must have reviewed the article, agree with the order of their names, with the content and final form, and be in a position to publicly defend its content. When submitting the request for publication of the article, the Editorial Committee assumes that this has been fulfilled, under the moral responsibility of the sending author.
Partial contributions to only some of the phases accredit the inclusion of their names in the Acknowledgments section, but do not justify co-authorship of the article.
In the Acknowledgments section, the authors must attribute the respective credits to all the people and institutions that have contributed to the research, including students. Likewise, the sources of financing or logistical support that made their work possible should be acknowledged.
The author should not submit changes to the content of his work after it has been accepted and returned to him to make the proposed corrections. If there is a compelling reason to make changes, the author must inform the Editorial Committee, which has the authority to approve or not the proposed changes.
The editors may request the justification of the participation of all the authors in the case of articles with numerous authors or in other cases where this information is required.
To allow replication of experiments, authors must make available information about the materials, data, standards, protocols, and references associated with their research.
Unique materials (algorithms or computer programs) should be made available to researchers who request them directly from the authors.
The author must not fragment his research work for publication. The authors who have carried out their work on a system or group of related systems will organize its publication with the purpose that each article gives a complete description of a special aspect of the general study. It is unethical for an author to submit for publication more than one paper describing the same research or project. This unnecessary subdivision scatters scientific information and makes it difficult to collect later. Occasionally, there may be valid reasons for such fragmentation, if this is the case, the authors must justify, in an independent communication to the editor, the reasons that support this fact.
The Editorial Policy of the journal in relation to ethical conflicts establishes that the authors will be morally obliged to declare if there is any financial, personal or professional interest -for reasons other than those of simple interest in contributing to science- in the publication of this article. This statement does not in any way invalidate its publication, but it is an element that the reviewers deserve to know in order to make an impartial interpretation of the published article. To support impartiality in the face of potential conflicts of interest, funders should not participate in the design, data collection, analysis of results, or preparation of the manuscript.
The journal can correct errors detected after publication, if requested by the authors, as long as the basic results or conclusions are not altered. If the errors are of a major nature, retractions or errata may be published on errors that affect the validity of the results obtained, at the discretion of the editors.
Policies regarding the work of referees


The referee must objectively judge the quality of the manuscript on its own merits and will respect the intellectual independence of the author or authors. Personal criticism is not appropriate.
He will express his opinions in an objective, precise, clear, truthful and convincing manner, in particular negative judgments, so that the editors and authors can understand the basis of his observations.
There can be no conflict of interest between the authors of the manuscript or the people involved (such as family relationships, colleagues, competitors or collaborators among potential referees or editors) and the referees. If a manuscript submitted for review represents a potential conflict of interest or the referee has a personal opinion about it, he must return the manuscript without delay and without review.
Reviewers must be selected in such a way that they have not shared authorship of any article or collaborated directly with the authors in the last 12 months.
