a Water-energy synergy index (WESI) at a global view. The larger the value, the greater the surplus of new energy and the drier the conditions in the area; conversely, the smaller the value, the lower the surplus of new energy (or the more abundant the water resources). Refer to Supplementary Method 1 for detailed calculations. b MSP2W is proposed to cost-effectively store the surplus renewable energy for sorption-based AWH. During off-peak hours, renewable energy is stored as high-temperature thermal energy. Meanwhile, the MSAWH absorbs moisture in batches from the ambient environment. c During on-peak hours, the stored thermal energy is used for desorption of the multi-stage water harvester.
