How to do an electrical energy audit

 What

A home energy audit is a tally of all of the heat and electricity use in your house. This describes an electrical energy audit, in which you assess the electrical energy demand of the appliances in your home or work in order to find ways to reduce. Often this is done using a spreadsheet and an energy meter such as a Wattson

 

 Why

Before we start, here are some definitions.

Voltage (V)
Charge pressure measured in volts (V)

Current (I)
Flow of charge measured in amps (A)

Power (P)
Electrical power measured in watts (W)

Energy (E)
Electrical energy measured in watthours (Wh).
Usually seen in kilowatt-hours (kWh) or (kW-hrs), 1000 watthours.

Loads
Any electrical device plugged into the wall.

Phantom loads
Truly frightening beasts that suck energy even when devices are ‘’off’’’.

 How
