Chapter 4. Water and coastal regions Water efficiency and conservation When water is scarce, supply can be strengthened through water storage tanks and other solutions. Or we can try to reduce demand. To support these measures, proven and new technologies are helping us identify water sources and leaks, save water for when it is needed the most, and make sure it is used
Water transportation and storage also need to consume energy. Consumption coefficients for the primary energy sector by water consumption divided by sector material output like coal, oil and gas production which had been transferred to standard value are got. Energy and water conservation has become an important component of the Chinese
This analysis framework allows the policy makers and researchers to quantify the potential of nexus between water saving and energy conservation.

(3) The key sectors differ according to the three perspectives.
India is a sub-continent with different physiography, climate, and agro-ecology. This variability supports changes in rainfall and water resources across the country. Due to various developmental activities such as agriculture, industry, and services, the ever-increasing demand for surface water and groundwater resources is declining at an alarming rate.
Strategically significant water is also stored in or behind structures such as dams, tanks, retention ponds, farm fields, or paddies. Storage may also be a combination of natural and built (sometimes also called green and gray solutions). For example, built structures are used to accelerate the recharge of natural underground storage.
Providing energy services (for example, demand response, frequency regulation and so on) may advance the worthy goal of enhancing system affordability, but the degree of energy flexibility in the water asset, and the extent to which flexibility is deployed, depend on first meeting water system reliability targets.
The water sector has a diverse set of mechanisms for delivering energy flexibility (Fig. 1a). In water transmission infrastructure, operators can modulate energy load by switching between different raw water sources with different energy intensities or by temporarily turning off pumps and relying on stored water 22.
Freshwater storage is at the heart of adapting to climate change, most obviously by saving water for drier times and reducing the impact of floods. Water is at the center of economic and social development; it influences whether communities are healthy places to live, good places to grow food, or have reliable clean energy.
Traditionally, water storage has focused on dams and reservoirs, but this approach will not meet the challenges of the 21st century in many areas. The report offers a framework to integrate and maximize the benefits of all forms of water storage: natural, hard infrastructure, and a combination of both, throughout an entire watershed.
Energy intensity and electricity costs vary considerably across the water sector 19, 20; electricity typically represents approximately 30–50% of advanced water treatment lifetime costs, 60–80% of distribution and transmission costs and 20–30% of wastewater treatment costs 20, 21, 22.
