Spatial Analyses of Electricity Supply and Consumption in Turkey for Effective Energy Management and Policy-making - Implementing Environmental and Resource Management - page 162

KDE is used as the first exploration approach to analyse 2008 electricity genera-
tion and 2006 electricity consumption data from the 81 provinces in this study.
Four different kernel bandwidths were selected based on trial and error. Only the
result from a 225 km bandwidth map (see Figures 14.8 and 14.9 ) gives a realistic
result.

225 km)
Since KDE is used to find the intensity values of a given pattern, it does not re-
quire any statistical inferences, and a significance level cannot be assessed. As
seen in Figure 14.8 , four clusters comprising the electricity generation capacities
of the Marmara Region can be clearly seen. Istanbul is at the centre, the central
Aegean Region and the area around Izmir, and the western part of the southeast
Anatolian Region, covering Diyarbakır, Şanlıurfa, Kahramanmaraş, Adana, and
Osmaniye are also seen. Figure 14.9 shows the Kernel function result for electric-
ity consumption in 2006. There are four clusters throughout Turkey. The first and
most prominent cluster is located in the northwest region of the map, while the
second cluster is in the west on the Aegean coast. The third cluster is observed in
the western part of the South East Anatolia, and the fourth cluster is in Central
Anatolia around Ankara.
