A VAr meter only measures the reactive (imaginary) power.
Apparent power is a combination of real and reactive power; thus having a VAr meter will not suffice to measure apparent power. Likewise, because the VAr meter only measures reactive power, it does not provide any information on real power.
Energy meters monitor the supply voltage and the in-phase component of the load current -in other words, they read true (real) power not apparent power which, when time is taken into account (i.e. by the rotation of the meter's disc), results in a measure of energy consumed.
Apparent power must be used for this is the total amount of power you need to generate. Apparent power includes all the loses of energy while real power is the power used by the electrical appliances. If you are talking about environmental impact then apparent power is the one you need because this is the overall power needed.
Watts measure real power, while VA (volt-amperes) measure apparent power. Real power is the actual power consumed by a device, while apparent power includes both real power and reactive power. In simple terms, watts represent the actual work being done, while VA accounts for the total power used by a device.

No, mvar (megavolt-ampere reactive) is a unit of apparent power while MVA (megavolt-ampere) is a unit of real power. Mvar is used to measure reactive power, while MVA is used to measure total power (both real and reactive).
To accurately measure and monitor the energy consumption of your devices using a computer power meter, you can connect the power meter between the device and the power source. The power meter will display real-time data on energy usage, allowing you to track and analyze the power consumption of your devices over time.
According to Wikipedia, all forms of power can be expressed in Watts, but typically one expresses only REAL Power in Watts (& Kilowatts).The standard is to express Apparent Power in Volt-Amperes (VA) (& KVA).The kilowatt is the unit of measure for true power; apparent power is measured in volt amperes.However, the volt ampere and the reactive volt ampere (for reactive power) are traditional units, used to help differentiate between apparent, true, and reactive power. SI recognises the watt as the unit for each.
No, volt-amps (VA) and watts (W) are not the same. Watts measure real power in an electrical circuit, while volt-amps represent the apparent power, which includes both real power and reactive power.
The ratio of active power (real power) and apparent power is called power factor ( pf ). Power Factor ( pf ) = Active Power / Apparent Power = .................. ( kvar )
Volt-amperage, or apparent power, is measured in volt-amperes (VA) and can be calculated by multiplying the voltage (in volts) by the current (in amperes) in an electrical circuit. To measure it, you can use a multimeter or a clamp meter to determine the voltage and current, and then apply the formula: VA = Voltage (V) × Current (A). For AC circuits, it's important to consider the power factor if calculating real power in watts.
Watts measure real power in an electrical circuit, while volt-amps measure apparent power, which includes both real and reactive power. Watts represent actual energy consumed or produced, while volt-amps account for the total power flowing in a circuit.
real power is to do do work and it is supplied to the load ,where as the reactive power is used for magnetising and the apparent power is the total power
