The potential for photovoltaic-powered pumped-hydro systems to reduce emissions, costs, and energy insecurity in rural China

Homes in rural China often have access to water wells for domestic and agricultural use. Given the significant difference in height between the well water and the roof of the house, such an arrangement could be used as a solar-powered pumped-hydro energy generation system. These systems could both limit increases in carbon emissions from coal-powered electricity while alleviating energy insecurity, while providing significant savings to households. The potential for these systems in rural regions across Shaanxi province is investigated by assessing eight key environmental and socioeconomic indicators. The find is that positive impacts across almost all indicators with generally rapid investment payback periods of 6.4–8.1 years, annual net income increases of 314.2 CNY −541.6 CNY per year per household. This research laid a theoretical foundation for the promotion of PV-PH system in Shaanxi Province.
