The two given pie charts illustrate how different industries used electricity in 1995 and 2005.
Overall, it is clear that manufacturing accounted for the largest proportion in both years, while service represented the smallest proportion in 1995. In addition, the proportions of household and service increased, whereas those of food, fishery and manufacturing decreased.
In 1995, manufacturing accounted for 33%, making it the largest category. This was followed by the proportion of food and fishery, at 24% and 20%, respectively. Meanwhile, household and service accounted for smaller shares, at 15% and 8% respectively.
By 2005, the proportion of manufacturing decreased from 33% to 31%, while the shares of food and fishery also fell, from 24% to 21% and from 20% to 13%, respectively. In contrast, the proportion of household and service both increased from 15% to 20% and from 8% to 15%, respectively. The most notable change was seen in fishery, which experienced a 7% decline. By contrast, service almost doubled its share over the period.
