Abstract

This study assesses the techno-economic and environmental aspects of solar photovoltaic (PV), diesel, and electric water pumps for irrigation in Assam, India. Two practical crop rotations are considered: Sali rice, strawberry, and Ahu rice; and Sali rice, mustard, and Boro rice. A comprehensive analysis, including performance, cost-effectiveness, and CO₂ emissions, was conducted through field surveys and data analysis. The findings highlight the advantages of solar photovoltaic water pumps (SPVWP), including reduced CO₂ emissions, lower operational costs, and the potential revenue from selling surplus electricity generated and participating in carbon trading. The study explores the sensitivity to varying subsidy rates, emphasizing the potential to promote SPVWP adoption through revised policies. Factors like crop rotation, energy costs, and groundwater availability are also considered. SPVWP emerges as a viable and sustainable irrigation solution in Assam and similar regions with appropriate financial incentives and support. The research offers valuable insights for policymakers and advances the understanding of renewable energy-based irrigation systems.

印度阿萨姆邦太阳能光伏、柴油和电动灌溉水泵的技术经济和环境评估

本研究评估了印度阿萨姆邦用于灌溉的太阳能光伏（PV）、柴油和电动水泵的技术经济和环境方面。考虑了两种实际的轮作：萨利水稻、草莓和阿湖水稻；萨利米饭、芥末和波罗米饭。通过实地调查和数据分析进行了全面分析，包括性能、成本效益和二氧化碳排放量。研究结果突出了太阳能光伏水泵的优势，包括减少二氧化碳排放、降低运营成本，以及出售剩余发电和参与碳交易的潜在收入。该研究探讨了对不同补贴率的敏感性，强调了通过修订政策促进SPWP采用的潜力。还考虑了作物轮作、能源成本和地下水可用性等因素。SPWP在阿萨姆邦和类似地区成为一种可行且可持续的灌溉解决方案，并提供适当的财政激励和支持。这项研究为决策者提供了宝贵的见解，并促进了对可再生能源灌溉系统的理解。

期刊介绍： Energy policy is the manner in which a given entity (often governmental) has decided to address issues of energy development including energy conversion, distribution and use as well as reduction of greenhouse gas emissions in order to contribute to climate change mitigation. The attributes of energy policy may include legislation, international treaties, incentives to investment, guidelines for energy conservation, taxation and other public policy techniques. Energy policy is closely related to climate change policy because totalled worldwide the energy sector emits more greenhouse gas than other sectors.
