Efficient Energy Please, the Japanese Do it with Ease

Everyone these days seems to be obsessed with saving energy. The word “sustainability” and “go green” seem to be all that were hearing these days. Some people hear these ideas of being energy efficient and it goes straight in one ear and out the other. Some countries however, truly want to create  a sustainable, energy efficient environment, and currently Japan sets the highest standard as the most energy efficient country (Figure 1).

Figure 1:


Japan has always prided itself off being 30 years ahead of other global super powers in terms creating an energy efficiency initiative. After the 1970 increase in oil price (figure 2) it was evident that “if something wasn’t done, life wouldn’t be sustainable” . Japan and several other countries suffered economically and Japan’s economy in particular “was on the brink of collapsing. This prompted the Japanese government to take initiative and increase energy efficiency across their country.

Figure 2:


The Japanese government has had a great influence over the Japanese people and their energy efficiency. In doing so, the government established several movements and laws in hopes of creating a sustainable country. Several conservation laws were passed forcing factories to replace old inefficient boilers and assembly-line machinery with new energy efficient equipment. There is also a law put into place which requires each factory to hire an individual who is in charge of overseeing factory energy efficiency. This is a very demanding job as by law, Japanese factories are required to become more energy efficient by one percent every year.  Japanese individuals have also started movements such “Setsudan” which emerged to “encourage people and companies to conserve energy and prevent rolling power cuts”. Japanese individuals will increase temperatures in homes and offices, thin lighting by removing some of the bulbs, and stop using big screen and exterior lighting in hopes of cutting back on energy.  These cut backs in energy use are obviously working as”Japan’s industrial sector uses the same amount of energy as 40 years ago, despite the dramatic economic growth since then”. These laws and movements have now become a Japanese way of life as most families live and operate in energy efficient manners.

Japan faces extreme temperatures in the Summer however typical Japanese families rarely uses their Air Conditioners. Most Japanese have AC units in every room of their homes. In doing so this enables them to save energy in the long run. AC units are only turned on in rooms which are occupied this saves more energy compared to having constant central air. Not only this, but the Japanese also have power strips with individual on/off switches so that their appliances won’t waste energy. Most families also purchase LED lights as well to conserve light energy. Families even save water by sharing bathwater; some individuals even have bathtubs that talk to them and warn them when they are wasting energy (figure 3) . Families are also prompted to conserve energy because of the high energy bills which costs twice as much in Japan as in the US, because Japan imports nearly all of it’s fossil fuels. 

Figure 3:


No matter what the motivation is for the Japanese, whether it is fear of high energy bills, or the fear of living in an unsustainable environment, Japan is setting a great example for the rest of the world in terms of energy efficiency.  In fact, recently Obama mentioned Japan as a country we should strive to be like in terms of our own energy consumption in the US.  Although it could take sometime, I am very hopeful that with some new laws and green initiatives, the US can soon become a green, sustainable country which excels in energy efficiency as well.
