Integration of Renewable Energy in Food Processing and Farm Mechanization: A Review

Abstract

Energy is a critical input in modern agriculture and food processing systems, influencing productivity, profitability and sustainability. The growing demand for energy in the agri-food sector, coupled with the challenges of fossil fuel depletion and environmental degradation, necessitates the transition toward renewable energy sources. This review discusses the role, potential and applications of renewable energy in food processing and farm mechanization. The paper highlights key renewable technologies such as solar, biomass, wind, biogas and small hydropower, along with their integration in operations like irrigation, drying, milling, cooling, packaging and transportation. Barriers, policy initiatives and future prospects for renewable energy adoption in agriculture are also analyzed. The study concludes that integrating renewable energy technologies can significantly reduce greenhouse gas emissions, lower operational costs and promote sustainable rural development.
