摘要

This study develops a 20-year Energy-Water-Food Nexus model for an arid region (2020–2040), focusing on food and energy security, efficient resource utilization, and minimizing environmental impacts. The model indicates that in the baseline scenario, renewable energy and carbon capture technologies supply an average of 12.5% of electricity demand over the 20 years. With the implementation of the emissions reduction scenario, which results in a 30% reduction in Carbon dioxide equivalent emissions compared to the baseline year, this share increases to 33%, with solar energy reaching full capacity by 2030. The contribution of greenhouse farming to food production rises from less than 1% in 2020 to 89% by 2040 under the emissions reduction scenario. The model predicts that in the baseline scenario, 288,000 jobs will be created over 20 years, with 30% of these jobs stemming from the development of greenhouse farming. Under the emissions reduction scenario, this figure increases to 334,000 jobs, primarily driven by the expansion of renewable energy. The implementation of the emissions reduction scenario leads to a reduction of 6 million tons of Carbon dioxide equivalent over the 20 years. Sensitivity analysis indicates that rising natural gas prices (1 to 15 cents per cubic meter) and electricity prices (1 to 10 cents per kilowatt-hour) facilitate the transition towards renewable energy. This study provides valuable insights for policymakers in achieving sustainable energy and food security while fostering green job creation and reducing emissions.
