A newer commercial use for pyrite is as the cathode material in Energizer brand non-rechargeable lithium metal batteries. [20] Pyrite is a semiconductor material with a band gap of 0.95 eV. [21] Pure pyrite is naturally n-type, in both crystal and thin-film forms, potentially due to sulfur vacancies in the pyrite crystal structure acting as n ...
[1] [2] Water efficiency differs from water conservation in that it focuses on reducing waste, not restricting use. [3] Solutions for water efficiency not only focus on reducing the amount of potable water used but also on reducing the use of non-potable water where appropriate (e.g. flushing toilet, watering landscape, etc.).

[11] The conservation of water is extremely important in order to preserve wildlife habitats.
In economics, a common-pool resource (CPR) is a type of good consisting of a natural or human-made resource system (e.g. an irrigation system or fishing grounds), whose size or characteristics makes it costly, but not impossible, to exclude potential beneficiaries from obtaining benefits from its use.
Charges for the use of water are among the best known economic instruments for water policies. They can contribute to the transmission of market signals which are coherent with policy aims, if their design is transparent and revenues are earmarked to uses connected to the service or to the mitigation of impacts from water uses.
End uses of water for households in the U.S. in gallons per household per day and percent of indoor use [1]. Residential water use (also called domestic use, household use, or tap water use) includes all indoor and outdoor uses of drinking quality water at single-family and multifamily dwellings. [2]
