“…Hu et al [12] found that water used in the energy-related sub-sectors accounted for about onefourth of the water used in the whole industrial sector and about of 3% of the total fresh water used in Beijing in 2009. To identify and understand the water and energy nexus in industries is crucial for exploring the possible measures for water and energy savings as well as CO 2 emission reduction.…”

“…End-users account for most of the water-related energy use (about 73%), rather than water conveyance and transport (about 20%). Hu et al [12] indicated that the electricity required for water supply, treatment, utilization, and post-use utilization comprised about 5-7% of total electricity consumption in Beijing in 2009. Thus, efficient use of water by end-users is very important for future water and energy conservation.…”

Water is needed to generate energy. Energy is required to deliver, clean, and evaporate water. There are extensive linkages between water and energy. Meanwhile, both resources may limit the other, especially in the context of urbanization and industrialization as well as climate change. Due to the large population and fast-growing economy, China is one of the most water and energy shortage countries in the world. Relations between water and energy are particularly strained. Unfortunately, up to now, little attention has been paid to the tension relation between water and energy in China. Studying water and energy nexus can provide more information than investigating them separately because of their concomitant relationship. In this paper, we reviewed the recent situations on these issues in China, mainly focused on the following topics: 1) energy consumption in water industry; 2) water consumption and energy nexus in energy industry and urban; 3) water and energy nexus in agriculture; and 4) Energy consumption by evapotranspiration and its cooling effect on reducing urban temperature. Extensive data are analyzed and reported in this study, which will be useful for policy making by taking account of climate change, urbanization, and population growth.

“…A Sankey diagram presents the distribution and linkage of water and energy to map and visualize the source, destination, and quantity of flows in each stage of the water and energy supply chains (Hu et al, 2012). The diagram represents the flow amount with different arrow widths, which intuitively visualizes the allocations and linkages among elements.…”

“…The diagram represents the flow amount with different arrow widths, which intuitively visualizes the allocations and linkages among elements. This diagram has been applied to visualize the nexus between water and energy on a household scale in Australia , regional scale in Beijing, China (Hu et al, 2012), and national scale in the USA (USDOE, 2014). The Sankey diagram is a decent visualization tool to describe the supplies and usage of resources in an intuitive manner.…”

Water, energy, and food nexus: review of global implementation and simulation model development

2017

View full text Add to dashboard Cite

Water, energy, and food (WEF) have complex interconnections. Water is required to produce energy, while energy is needed for water extraction, treatment, and distribution. The food sector requires water and energy to produce food products, while fertilizer and pesticide from farmland have a negative impact on water quality; however, biomass is a potential alternative energy source. Understanding these interconnections will help determine the developmental framework that connects all of the elements. Some global regions have implemented a variety of sustainable management concepts to manage the natural resources, however, mainly for an individual resource. Furthermore, various computer models have been developed to estimate the interdependency of each resource and to quantify future requirements of WEF; the limitations of current models have opened opportunities for development through the addition of components and features such as feedback analysis, optimization, and visualization. We reviewed the literature to determine the present state of the WEF nexus, especially its global implementation and simulation model. We concluded that the involvement of stakeholders, integration of policies, and development of a nexus simulation model are required for successful implementation of the WEF nexus, which is an emerging issue for a sustainable resources' management.

China has promised to optimize its energy structure and reduce its CO 2 emission in the 13th FiveYear Plan. To track the energy structure, the conversions, efficiencies, end consumptions of total energy and coal and the whole CO 2 emission status, the energy flow, coal flow and CO 2 flow in 2015 were, respectively, drawn at the national level based on Sankey diagrams. Besides, each provincial fossil fuel structure, CO 2 structure and CO 2 intensity were calculated and plotted. It is mainly found that China's energy structure consisted of 69.2% of coal, 19.9% of oil, 6.3% of natural gas and 4.7% of non-fossil energy, where 45.5% of energy was consumed by industry and 23.9% by losses and statistical difference; coal was distributed to industry (55.6%), etc., with a utilization rate of 70.1%; and CO 2 were derived from coal (84.7%), oil (11.1%) and natural gas (4.2%), of which 39.0% was released through the process of thermal power generation and 19.4% by industry. The structures of fossil fuels and their CO 2 emissions together with the evolution of CO 2 intensity at the provincial level and the regional level were also given. Besides, two pieces of policy implications were proposed to provide the government with reference.
