tries are agriculture alongside basic commercial activities. It should also be noted
that a few provinces in this group have a higher population than those with similar
provincial economic characteristics in the west; however, their consumption figure
is considerably different. This result is mainly due to the very high electricity
leakages in these provinces (e.g., Diyarbakır, see TÜİK 2008).
14.3.4 Sectoral Electricity Consumption in Turkey
Based on available consumption data, the sectoral electricity consumption was
also visualised for the 10-year period from 1997 to 2006. Only two of the years
(1997 and 2006), however, are presented here ( Figures 14.6 and 14.7 , respec-
tively). The pie charts on these figures display data only from those provinces that
have consumption greater than 900,000 kWh for 1997 and 1,500,000 kWh for
2006. Additionally, the line mentioned above, which divides the country into two
segments based on consumption (see subsection 14.3.3), is also seen in these fig-
ures. The size of the pie chart reflects the amount of electricity being consumed;
larger pie charts represent larger consumption. These maps are useful because they
provide information regarding the changes in sector size during the 10-year pe-
riod. For example, the industrial sector electricity consumption in Istanbul, which
is represented by the largest pie chart in the northwest ( Figure 14.6 ), is almost half
of the total consumption in 1997, whereas in 2006 it represented only 1/3 ( Figure
14.7 ). This change may be due to the switch in Istanbul's economic activity as the
focus changed from an energy intensive industry to the service sector.

Examining the consumption in Ankara, the capital city of Turkey, it is clear that
neither the industrial nor the domestic sector has changed significantly during the
same 10-year period. On the other hand, Figure 14.6 and Figure 14.7 show that in-
