Submitting to Cleaner Energy Systems goes smoothly when your draft already matches the journal's own rules. Editors screen new manuscripts against the Cleaner Energy Systems guide for authors before peer review, so formatting, structure, and required statements should be right on the first draft rather than repaired during upload. This template sets that structure up for you.
It is a manuscript shell aligned to Cleaner Energy Systems. It covers front matter, the abstract the journal expects, a body organized to the journal's article types, and a reference list in the journal's required style. Confirm current scope and article types on the Cleaner Energy Systems journal page before you draft.
Prepare the title, authors, affiliations, and ORCID iDs. Write the abstract to the journal's rule and word limit, organize the body to the article type, and apply the required reference style from the first citation. Complete every declaration (ethics, competing interests, funding, data availability) the Cleaner Energy Systems guide for authors lists, and cite figures and tables in order.
The common failure modes are formatting or reference style that does not match the guide for authors, missing required statements, and an incomplete portal checklist. Clear all three against the Cleaner Energy Systems guide for authors before you submit.
The shell mirrors what editorial staff check first: article-type fit, the abstract rules, required declarations, and the journal's reference style. For more detail see the author resources. When your draft is ready, upload it through the journal's submission system.
| Element | Clean Energy Syst requirement |
|---|---|
| Abstract | Unstructured abstract with a maximum of 250 words. The abstract should briefly state the purpose of research, principal results and major conclusions. Abstracts must be able to stand alone and should avoid references (if essential, cite author(s) and year(s)). Non-standard or uncommon abbreviations should be avoided or defined at first mention |
| Main text | Original article: 6000-8000 words in length (including tables, illustrations and references). Review article: up to 12,000 words (must include a Methods section explaining how literature for review was selected). Letters to the Editor: length not specified in guide |
| Declarations | Ethics approval/consent as applicable; competing interests; funding; data availability |
| Figures/tables | Publication-ready; cited in order |
| Supplemental | Upload separately when used |
| Keywords | Required: 1 to 7 keywords for indexing purposes. Keywords should be written in English. Authors should try to avoid keywords consisting of multiple words (using 'and' or 'of'). Abbreviations should only be used in keywords if they are firmly established in the field |
| References | Author-date style (Harvard style). Citations in text refer to author name(s) and year. Reference list arranged alphabetically then chronologically. Journal names abbreviated according to List of Title Word Abbreviations (LTWA). At submission, references can be in any style or format as long as consistent; journal reference style will be applied at proof stage after acceptance |
| Peer review | Single anonymized review (single-blind). Submission is initially assessed by editors for suitability, then typically sent to a minimum of two reviewers for independent expert assessment of scientific quality. Final decision on acceptance/rejection is made by editors |

Read the Cleaner Energy Systems guide for authors once before drafting and once before upload. Draft the abstract after results are stable. Set the reference style before adding citations. Keep a cover letter that states your contribution and fit to Cleaner Energy Systems in under a page.
Skim two or three recent Clean Energy Syst papers to calibrate depth and figure style. Make the novelty clear in the first two pages. Deposit data and code when the policy on the Cleaner Energy Systems journal page requires it. Disclose any preprint or conference version with identifiers in the cover letter.
Do one focused pass against the Cleaner Energy Systems guide for authors: scope, length, reference style, required declarations, and figure quality. Then submit through the journal's submission system.
