<p>The study evaluates the energy efficiency and investment strategies for sustainable apple production in the Kashmir Himalayas, focusing on the southern region of the valley. It employs Data Envelopment Analysis (DEA), a mathematical method, to assess how efficiently energy is used in apple farming in South Kashmir. The analysis optimises the input-output relationship by reducing inputs such as fertilisers, chemicals, labour, and machinery, while maintaining apple yields. Results reveal significant differences in energy consumption across orchard sizes, with smaller orchards using inputs more intensively than larger ones. The findings highlight opportunities to improve energy efficiency, particularly in human labour and fertiliser use. By aligning with Sustainable Development Goals (SDGs), especially SDG 7 (Affordable and Clean Energy) and SDG 12 (Responsible Consumption and Production), the study offers valuable insights for boosting economic benefits without compromising environmental sustainability. This research enhances understanding of energy management in horticulture, aiming to balance productivity with environmental responsibility in apple cultivation.</p>
