Global energy consumption of water treatment technologies

• Spatial estimates for the global energy consumption of water treatment are given. • A high-resolution model was developed for the major water treatment technologies. • Water treatment accounts for 1.8–5.4 % of total global electricity consumption. • The framework can be applied to understand water-energy system interactions. • Future efforts should be directed towards improving data collection and reporting. Access to safe drinking water and sanitation is crucial for protecting human health and achieving many Sustainable Development Goals. However, the provision of these services requires significant amounts of energy, which are poorly quantified at the global scale. In this study, we develop a spatially…
