Kilovolt Amperes (KVA)
Also known as Total Power. The resultant effect of the active (kW) and reactive (kVAr) power is the total power measured in kVA. KVA = kW/power factor.

Kilo-volt-amp (kVA)
One thousand volt-amps, an assessment of electrical usage (or potential usage) calculated by multiplying volts by amps.

Kilo-volt-amp-reactive-hour (kVArh)
A unit of measure of poor power factor

Kilowatt (kW)
A standard unit of electrical power equal to 1000 watts, or to the energy consumption at a rate of 1000 joules per second, 1kWh is approximately equal  to 0.0341 therms.

Kilowatt-hour (kWh)
The volume of energy supplied at the rate of one kW for one hour.

Kyoto Accord
Agreed in Japan 1997 targets 'carbon-rich' gases and commits 38 industrialised countries to emissions cut of 5.2% by 2010.

Kyoto Protocol
In 1997, representatives from over 170 nations met in Kyoto, Japan to put together a new global treaty - the Kyoto Protocol to the United Nations Framework Convention on Climate Change (UNFCCC) - laying down legally binding reductions in greenhouse gas emissions throughout developed countries emissions by an average of 5.2 per cent below 1990 levels over the period 2008-2012.
