JESA information for authors

The Journal of energy in Southern Africa publishes papers covering the technical, economic, policy, environmental and social aspects of energy research and development carried out in, or relevant to, Southern Africa. Contributions, in English, from those working in these fields are welcome. All full-length articles are refereed, and amendments to scripts and formats may be required before final acceptance.

Agreement by authors when submitting manuscripts 

Only original work will be accepted. By submitting work for a consideration to publish in JESA, the author grants the publisher a worldwide, non-exclusive, royalty-free and perpetual licence to reproduce, publish and distribute the author’s work in any format or medium. The author agrees that the contribution is an original work, was not published elsewhere, is not being considered for publication elsewhere, and will not be submitted for publication elsewhere unless rejected by the Journal of energy in Southern Africa or withdrawn by the author. Neither the editorial staff, the board nor the publisher accepts responsibility for the opinions or viewpoints expressed, or for the correctness of facts and figures.

Proposed reviewers

The journal practices a double blind author-reviewer interactive process. In a separate document, the author proposes four reviewers for the article, giving their names and credentials (title, name and surname, including middle initial when available, organisation/institution, discipline and position, email address). Potential reviewers are most likely those that have published in at least one accredited international in the last five years and may be sourced from the list of references. Such reviewers most certainly have expect knowledge of the topic at hand and at least two of them might be ready and willing to review the manuscript within the stipulated time, thereby rendering an effective peer-review that will raise the impact of the study. Any possible conflict of interest with the proposed reviewer must be disclosed to the editor. Such a conflict of interest would include the following.

When the proposed reviewer

  • has ever co-authored with current authors,
  • was in the same organisation/institution as the authors’ in the last 3 years,
  • has played a role in funding mechanisms for the research,
  • has personal/special relationships with the resources of research (e.g. equipment suppliers, employees of affected organisation and owners of technology), or
  • is associated with the competitors or the opposition.

The editor retains the right to use or not use the proposed reviewers.

Presentation of the manuscript

Between 5000 and 7000 words.

Linguistic and other conventions

  • The text must use UK English spelling (including ‘-ise’ rather than ‘-ize’ suffixes).
  • Use single quotation marks.
  • Currency units: Use the ISO 4217 Currency Code (
  • Measurements: Use the International System of Units. The unit must separated from the number by a non-breaking space (in MS Word: control-alt-spacebar), except for %, min, sec.
  • Numbers or values:
    • Use a point for the decimal marker.
    • Use a non-breaking space to separate 1000s in long numbers (do not use a comma or a point) as well as between value and units.

Three 3 separate documents must be submitted, namely, (1) full title page including abstract, highlights and keywords; (2) full manuscript from title page to references; and (3) four proposed reviewers.

  • Ideally, the manuscript is submitted in MS Word.
  • Use a single column, no section breaks, and margins of 25.4 mm throughout.
  • Use Times New Roman 11 point throughout, and 1.5 line spacing.
  • Title page.
    • Title. To be left-aligned and bold.
    • Authors. Leave one blank line after the title and list all the authors on one line, their names separated by commas. If all authors were from the same affiliation (discipline, institution and address) or in case of one author only, leave one blank line and add author affiliations. When the authors have different affiliations, add a superscript 1, 2, 3, … at the last name of the author and define their affiliations respectively. Distinguish the corresponding author by adding an asterisk next to the superscript. Define the asterisk as “corresponding author, author’s telephone number and email address.
    • Abstract: Give a standalone heading (i.e. Abstract) and allow a single paragraph of not more than 250 words justified, which include the following.
      • One sentence of the theme/background/general statement about the study (optional).
      • State of the problem under investigation and the objective/importance of the study.
      • Give the study design and setting.
      • Give key findings/contributions/results.
      • End with a catchy/appealing indication of its implications for future or existing developments.
    • Keywords. Give a standalone heading (i.e. Keywords) and allow not more than five 5 words in one line, separated by commas and all in small case.
    • Give a standalone heading (i.e. Highlights) and allow not more than five 5 sentences of not more than 10 words each.   
  • Body of the manuscript: Start on the new page and make headings bold (e.g. Introduction) and numbered according to the system 1., 1.1, 1.1.1, …..6., 6.1, 6.1.1 etc.
    • Tag paragraphs as either Normal or Body Text, 1.5 line spacing, and justified. Use automatic spacing of 10 pt between paragraphs (and not an extra line).
  • When bullet points are used, they must accord with the punctuation of their context. A bullet point comprising complete sentences should start with a capital letter and end with a full stop. Incomplete sentences start with lowercase letters, end with a comma and the final bullet point ends with a full stop.
  • Equations are numbered from 1, with the number in parentheses coming after the equation and separated from the equation by a tab, taking it flush right to the end of the line. References to numbered equations within the text capitalise the E and excludes the bracket (e.g. …expressed as Equation 1).

Tables and figures:
All tables and figures must be referred to in the body of the text, starting with capital T or F (e.g. …as shown in Figure 1 or as presented in Table 1. Place the tables and figures as near as possible below text where first reference was made. Captions are placed before the actual tables, but below the actual figures respectively. Tables and figures are consecutively numbered, starting with 1 in all cases and followed by a colon before the caption. If not your original work, give citations, e.g.,

Figure 3: Cross-section view of a commercial PV module [1]

Figures must be of reasonable standard for reproduction at the time of manuscript submission, i.e. with crisp and clear drawings and labels. Labels take the font of manuscript. When the manuscript is finally accepted by JESA, authors may be requested to submit better quality illustrations. Note, for example, that downloads from the internet often do not meet a publishable quality for an academic journal. Otherwise the editor may decide to exclude the illustrations or retract the manuscript.

Bibliographic management:
Tool: Endnote is a downloadable MS Word and MS PowerPoint plug-in recommended by Thomson Reuters and by universities and is, therefore recommended by JESA. It allows reliable, effective, and efficient reference management system.   

Citations: Use one of two systems. Preferably, citations should be numbered in brackets, e.g. [1, 2, 3], and, where practicable, placed at the end of the sentence or statement. Use of numbered citations improves optimum use of document with respect to number of words in the text. The author/date system of notation may, however, be used.

Authors are encouraged to include citations mainly from accredited international journals. Sources outside scholarly published material and theses can be manually added in the reference library to conform with the automated style.

Reference list: Choose the Harvard System of reference, which is essentially automated but can be edited for consistency in respect with (1) author’s last name and initials, (2) title of publication/source (taking into account the general conventions of capital and lower case letters), (3) name of journal/source, (4) year of publication/source and (5) relevant pages.
