: [[Energy]] ([[kilowatt-hour]]s) = [[Power]] ([[kilowatt]]s) x [[time]] ([[hour]]s)

: The amount of [[energy]] an '''appliance''' uses depends on the power rating and how long the '''appliance''' is used for.

: [[Energy]] usage for '''appliances''' is measured in [[kilowatt-hour]]s. This means all [[power]] ratings need to be in [[kilowatt]]s and time should be in [[hour]]s.
