Electrical energy consumption in the eastern province of Saudi Arabia
is modeled as a function of weather data, global solar radiation, popu
lation, and gross domestic product per capita. Five years of data have
been used to develop the energy consumption model. Variation selectio
n in the regression model is carried out by using the general stepping
-regression technique. Model adequacy is determined from a residual an
alysis technique. Model validation aims to determine if the model will
function successfully in its intended operating field. In this regard
, new energy consumption data for a sixth year are collected, and the
results predicted by the regression model are compared with the new da
ta set. Finally, the sensitivity of the model is examined. It is found
that the model is strongly influenced by the ambient temperature.
