Evaluation of a Water Resources System based on Energy Efficiency

Abstract

In this study, we used electricity consumption data by the water cycle process provided in Korea. Through the data, we indirectly investigated the relationship between water and energy. A water supply and demand network was constructed to estimate the energy consumption for the water cycle process in the Geum River basin. Future water supply and demand prospects were modelled by configuring 15 possible scenario paths. An optimal water distribution method considering energy efficiency was suggested as an alternative to reduce areas and the magnitude of water shortage. The results of this study confirm that the expected magnitude of water shortages in the future and the amount of electricity consumed in the water cycle process can be significantly reduced. The relationship between water and energy and optimal water distribution methods considering energy efficiency proposed in this study are expected to be able to provide useful related information for future water resources planning.
