Of all 54 nuclear power plants in Japan, due to the breakdown of the power plant in Fukushima as well as some other nuclear plants being out of service for annual maintenance, we are now facing the upcoming shortage of electricity.
The government asked every office and manufacturing company to cut the 15% electricity usage from the previous year except hospitals and elderly care facilities in those areas up until the end of September. In many offices where there used to be quite formal dress code, men and women are now free from wearing neckties, long sleeves and jacket since a closed high-rise building temperature often gets over 28 degrees C. In many private and public buildings such as department stores, offices and stations, they now switch off some lights in the buildings.
Not only those public organizations but also everyone at home is now very much aware of how to economize the whole usage of electricity. Approximately 50% of electricity consumption at home during summer is used for air conditioners following a refrigerator, lightning, TV etc. So it is quite evident that the whole nation can save electricity so simply by way of giving up air conditions! Oh but No way! That's not possible. Summer in Japan is very hot and humid. In addition, the recent global warming spurs the summer temperature to over 35 degrees C. The heat is really ferocious. We can't do without air conditioners.
For example, they advise us we should set the temperature no lower than 28 degree C, clean a filter at least once a week, use a electric fan to circulate air in a warm room, etc. As for a refrigerator, they recommend us we should not pack many items, should use a plastic curtain to prevent warm air from coming inside when we open its door. Boy, there are many "to do" and "not to do". Yet despite these annoying advices, many people are so aware of power shortage and we are making a desperate contribution by sweating.
