中国小城镇的用电量 Electricity consumption in small towns in China

From the bar chart given above, we can observe that the electricity consumption in a small city experienced some changes during the past several years.
从上面给出的条形图中，我们可以看到，在过去几年里，一个小城市的电力消费经历了一些变化。
From 2004 to 2007, it increased by 2.51% from 4.6 million kilowatt to 4.723 kilowatt.
从2004到2007，从4600000千瓦提高到4.
However, it decreased by 0.8% from 4.723 in 2005 kilowatt to 4.7 kilowatt in 2006.
723千瓦到2.
Then it increased by 12.26 million kilowatt in 2007.
51%千瓦。
The bar chart reveals the phenomenon that the electricity consumption rises with some fluctuations.
然而，它下降了0.
What exactly contribute to this phenomenon ?
8%，从4.
Reasons can be listed as follows: in the first place, with the improvement of financial status and living standard, electrical appliances such as television sets , refrigerators, washing machines , air conditioners and so on are becoming increasingly widespread , however all these machines will not only offer us great convenience, but consume more electricity.
723到2005千瓦，2006千瓦4.
Moreover, factories located around the city are also main factors of the rising of electricity consumption.
然后，它增加了12.
Last but not least, the absence of citizens consciousness of economizing on electricity also leads to the rising of consumption.
88%至5260000千瓦的2007。
The rapid increase of electricity consumption shows that it has been playing an indispensable role in our life.
条形图揭示了电力消耗随波动增加的现象。
Vital to all aspects of modern life, electricity is far from being sufficient.
究竟是什么促成了这一现象？
Accordingly, it is urgent that every one of us should foster the consciousness of saving electricity.
原因可以列出如下：首先，财务状况和生活水平提高，电气设备，如电视台，冰箱，洗衣机，空调等都变得越来越普遍，然而所有这些机器将不仅提供我们伟大的方便，但消耗更多的电力。

此外，工厂位于城市周边也是电力消费上升的主要因素。
