As we have commented in class, the most efficient measures are the simplest ones. It comes to my mind a news that I heard two years ago. It surprised me that so simple measure could result in such a great save of energy.

The measure was leaded by the Prime Minister of Japan, Junichiro Koizumi. He decided to save energy by reducing the consume of air conditioned in the companies. But how he could do this when the temperatures in summer usually reach to 28 degrees?
The measure consisted on dressing casual clothes instead of the ties and formal jackets usually dressed by the business people. This isn’t the first time Japanese officials have tried to get workers to dress cooler to save energy. In the early 1990s, former Prime Minister Tsutomu Hata made headlines promoting a short-sleeved suit. But the look didn’t catch on.

In Japan, air-conditioning accounts for a major share of household and office energy consumption. Statistics for 2004 show that the proportion of electricity consumption of air conditioners was 24.4 per cent, 16.5 per cent belonged to refrigerators and lighting consumed 9.6 per cent.

Koike Yuriko, the environmental minister, said the campaign was well accepted by the majority of companies and citizens. It helped reduce carbon emission by 460,000 tonnes in 2005 by significantly cutting electricity consumption during the four summer months. This reduction is very significant, because Japan is one of the world’s major producers of greenhouse gases, 8.5 per cent of global emissions.

Finally the conclusion is that this little measures could help to save energy and consequently reduce the damage to the environment.

    I am surprised that switching off the air conditions in Japan is such a big deal. A temperature in summer of 28 degrees is not that high that it cannot be supported even when putting tie and jacket.

    In Singapore, my colleagues and I regularly have to put on more clothes because the aircon is so high! The equatorial climate in Singapore means life can be very unconfortable without good ventilation, but much energy is wasted because of unnecessary air-conditioning. Sadly, more often than not, the aircon is centrally controlled and there is little we can do about it 😦
