The increasing worldwide demand for energy requires development
of intelligent forecasting methods and algorithms. The estimation
of energy demand based on economic and non-economic
indicators may be achieved by certain linear or non-linear statistical,
mathematical, and simulation models. The non-linearity of
these indicators and energy demand has led to a search for intelligent
solution approach methods such as genetic algorithms, fuzzy
regression, and neural networks. ANNs have been used in nonlinear
modeling and forecasting [1].
