Abstract

The water-energy nexus describes the connection between water and energy. Here we focus on energy for water supply to urban areas of China. Electricity use is one of the main costs for water companies and tends to be the main source of greenhouse gas emissions during water supply. In a country where reducing energy use and emissions is now an important part of the national agenda, managing energy use will become a major focus for the water industry. This chapter provides an overview of energy use at each stage of water supply in China: sourcing and transfer, water treatment, central distribution, and distribution within high-rise buildings. We then focus specifically on water distribution, which is a major energy user, and use statistical data from four cities in China and Japan to draw conclusions on how city layout affects the energy needed to supply water.
