The excessive focus on water mounts a challenge to the sustainable development. Energy is another aspect that should be taken into account. Nexus approach is characterized by an equal emphasis on energy and water spheres. In arid areas, like the city of Kashan, Iran, non-conventional waters (e.g. desalinated and recycled waters) have been considered as an alternative resource of water. Nexus wa...

Water, energy, and food are lifelines for modern societies. The continuously rising world population, growing desires for higher living standards, and inextricable links among the three sectors make the water-energy-food (WEF) nexus a vibrant research pursuit. For the integrated delivery of WEF systems, quantifying WEF connections helps understand synergies and trade-offs across the water, ener...

The energy-water nexus has been studied predominantly through discussions of policy options supported by data surveys and technology considerations. At a technological level, there have been attempts to optimize coupling points between the electricity and water systems to reduce the water-intensity of technologies in the former and the energy-intensity of technologies in the latter. To our know...

The paper inclines to briefly articulate major problems and critical questions exist in water, energy, food and climate (WEFC) nexus from artificial intelligent and law perspective. Then a legal knowledge framework, based on computational ontology, Akoma Ntoso and LegalRuleML standard, is proposed to identify WEFC nexus. It also presents a brief use case on the existing legislations of quality ...

Concerns about the water–energy–food (WEF) nexus have motivated many discussions regarding new approaches for managing water, energy and food resources. Despite the progress in recent years, there remainmany challenges in scientific research on theWEF nexus, while implementation as a management tool is just beginning. The scientific challenges are primarily related to data, information and know...

1 Recent droughts and heatwaves showed the vulnerability of the electricity sector to surface water 2 constraints with reduced potentials for thermoelectric power and hydropower generation in different 3 regions. Here we use a global hydrological-electricity modelling framework to quantify the impacts of 4 recent drought and warm years on hydropower and thermoelectric power usable capacity worl...

The operation and economic profitability of modern energy systems is constrained by the availability renewable water resources. Lower due to climate change, higher demand increased consumption for non-energy needs may cause problems in Africa. In most African power systems, hydropower a dominant resource, interconnection capacities are usually limited or unreliable. This paper describes new mod...

Modern energy systems use large amounts of water for electric power production. This has important impacts on future management and system planning decisions. In this study, we quantify the physical production virtual transfer via transmission between Chinese provinces using information 5408 electricity-generating units interprovincial transmission. We show that China’s withdrew 62.7 billion m3...
