The ratio of the total amount of power that might be used by the
headend or hub, to the power required for the critical or IT equipment--
includes power used for lighting, cooling systems, power distribution.
Power usage effectiveness (PUE)
total facility power used/total consumed power by IT equipment
PUE
a ratio of the total carbon emissions due to the total energy
consumption of the data center compared to the energy consumption
of the data center's servers and IT equipment.
Carbon Usage Effectiveness (CUE)
a ratio of the annual water usage to how much energy is being
consumed by the IT equipment and servers, and is expressed in liters/
kilowatt-hour (L/kWh).
Water Usage Effectiveness (WUE)

can be the result of long-term problems that create swells, or,
overvoltage can be thought of as an extended swell. Overvoltages are
also common in areas where supply transformer tap settings are set
incorrectly and loads were reduced.
Overage
result from long-term problems that create sags. The term "brownout"
describes this problem and has been superseded by the term
"undervoltage." Brownout is ambiguous in that it also refers to
commercial power delivery strategy during periods of extended high
demand. Undervoltages can create overheating in motors and lead to
the failure of non-linear loads such as computer power supplies.
Underage
occurs when the power level rises above normal levels and then drops
back to normal in less than one second.
