[[Electric power engineering]] deals with the production and use of [[electrical energy]], which can entail the study of machines such as [[Electrical generator|generators]], [[electric motor]]s and [[transformer]]s. [[Infrastructure]] involves [[Electrical substation|substations]] and [[transformer station]]s, [[power line]]s and [[Power cable|electrical cable]]. [[Load management]] and [[power management]] over networks have meaningful sway on overall energy efficiency. [[Electric heating]] is also widely used and researched.
