水资源竞争加剧、人口增长和全球气候变化将加剧世界干旱地区水资源和能源之间的紧张关系，因为能源成本凸显了干旱地区面临的水安全挑战。在加州的洛杉矶，水资源和能源之间的紧张关系最为突出。本文分析了该市目前的供水情况，并根据洛杉矶水电局的供水预测估计了其未来的能源需求。结果表明，虽然增加当地水资源管理策略可以降低未来供水的能源强度，但增加对调水的依赖可能会使其未来的能源强度恶化。
Abstract Increasing water competition, population growth and global climate change will intensify the tension between water and energy resources in arid climates of the world, since energy costs underscore the challenges facing water security in dry regions. In few places is the tension between water and energy resources more pronounced than in Los Angeles, California. This article analyzes the city’s current water supply and estimates its future energy requirements based on water supply projections from the Los Angeles Department of Water and Power. Results suggest that while increasing local water management strategies could reduce the future energy intensity of the water supply, an increased reliance on water transfers could worsen its future energy intensity.
