Abstract
This study explores how sweet potatoes can be used to produce bioethanol and biogas, making them clean and renewable energy sources. Sweet potatoes have a high starch content, are adaptable to various types of soil, and have weak competitiveness with food crops. These characteristics make it an excellent raw material for the production of biofuels. This study reviewed the agronomic and biochemical characteristics of sweet potatoes and how these characteristics affect fuel production and energy efficiency. In addition, this study also explored the main production methods, such as low-temperature enzymatic hydrolysis and anaerobic digestion, which are conducive to converting sweet potatoes and their waste into ethanol and methane. Several cases from China, Africa and Brazil have demonstrated how sweet potato bioenergy can function in real life. In China, rural factories use simple fermentation systems to produce ethanol. In Africa, families use sweet potato waste to produce biogas for cooking. In Brazil, large farms operate integrated biorefineries that simultaneously produce ethanol, biogas, animal feed and fertilizers. These cases demonstrate that sweet potato energy projects can increase farm income, create job opportunities and reduce pollution. This article also points out related challenges, such as the high cost of enzymes, storage issues, and limited policy support. Even so, with the improvement of breeding levels, technological innovation and the application of digital tools, the prospects for sweet potato bioenergy are very bright. The development of this industry helps reduce the use of fossil fuels and supports green and low-carbon growth.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
