Energy Assessment and Renewable Energy Opportunities in Post-Harvest Food Systems: A Comprehensive Review

Abstract

Energy efficiency and renewable sources are highlighted in this manuscript which discusses the use of energy in food systems after harvesting. Methodology provided aids in optimizing energy use in food processing. By highlighting both conventional and renewable energy technologies, such as solar PV and biomass, the manuscript proposes sustainable solutions that are timely and essential for combating climate change and food security challenges. The importance of standardizing energy data and improving energy efficiency within the PHF system aligns well with current global efforts to promote sustainable agricultural practices, making this research highly relevant to the scientific community. The focus on reducing fossil fuel dependence in post-harvest operations is particularly significant as it addresses both environmental concerns and long-term cost savings for the industry. Additionally, the inclusion of real-world case studies, such as solar drying in turmeric processing, strengthens the manuscript’s practical applicability. This review also highlights the practical benefits of renewable energy sources, including reduced carbon emissions and energy independence, while emphasizing the critical role of energy auditing in optimizing efficiency and sustainability. By integrating these approaches, we can enhance energy management and support a transition towards a greener future. Overall, the paper provides a robust foundation for future research and policymaking in sustainable food processing systems.
