Partial set of explanatory variables: Most previous studies have
analyzed only a partial set of residential electricity consumption
determinants; e.g., only appliance stock, weather conditions,
or behavioral factors [19,20]. However, interactions
among different factors (e.g., the relationship between
weather, appliance load, lighting load, and heating load) offer
considerable potential for improving energy efficiency [6].
Another limitation of some previous studies is the use of
“bundle” variables (such as Zip Code) that combine (hence
obscure) the effect of several underlying determinants.
