While in general more efficient water heaters are more expensive than conventional water heating technologies, the savings in energy use, and thus utility bills, can recoup the additional up-front investment and make an efficient water heater a good investment over time in most situations, although
Markets are already making a significant contribution to increasing rural water-use efficiency. But further reform is needed to ensure that water continually moves to its highest value uses (including environmental uses).

The dominant factors affecting crop production in Northeast China are the low amount of rainfall in spring and high loss of soil water through evaporation during summer, both of which contribute to the lower soil water use efficiency (WUE).

Abstract. The concept of crop water use efficiency (WUE), determined by the ratio between the marketable yield and the seasonal values of actual evapotranspiration, has become a suitable tool for analysing the strategies that allow attaining the best use of water in agriculture.
What is Consumptive Use of Water and Factors Affecting it It is the quantity of water used by the vegetation growth of a given area. It is the amount of water required by a crop for its vegetated growth to evapotranspiration and building of plant tissues plus evaporation from soils and intercepted precipitation.
