Foreword This book about Japan’s efforts on energy efficiency is part of the ISEAS Energy Series. The issue of energy efficiency has become one of the most important aspects in the global energy outlook today. The depletion of fossil fuels as energy resources as well as global warming as factors in global socio-economic development make it imperative for us to consider energy efficiency policies and measures as one of the most important priorities for policy-makers and every responsible global citizen. Japan has been a leading country in the area of ener gy efficiency. Since the 1970s when the oil crisis hit, Japan, which depends almost wholly on imported energy supplies from abroad, has been conducting various efforts on energy conservation and diversification of ener gy sources. As a result, Japan has achieved the lowest primary ener gy consumption per GDP in the world. Asian countries should learn from Japan’ s success in this area, especially since their economic growth is predicted to be one of the primary drivers for growth in global ener gy demand. The chapters in this book are based on presentations on Japan’s energy efficiency and conservation at ISEAS Energy Forums on two separate occasions. Professor Makoto Nishimura, former Executive Vice-President of the Mitsui Global Strategic Studies Institute Japan, and now an economic s professor at the Nagoya University ,

presented a paper on energy efficiency and new technology from the private business perspective, at the ISEAS Energy Forum on 7 March 2007. Together with Dr Ram Giri, Project Manager of the Mitsui Global Strategic Studies Institute (MGSSI), he addressed the challenges and problems on exporting Japanese ener gy saving technologies. Mr Yasushi Akahoshi, Executive Director of the Japanese External Trade Organization (JETRO) Singapore, which is the Japanese government agency dealing with cooperation in foreign trade, also wrote a chapter on the policy aspects of Japanese energy efficiency and conservation. This was based on his presentation at the ISEAS Energy Forum on 14 March 2007. We thank Professor Nishimura, Dr Giri and MrAkahoshi for their contributions to the ISEAS Energy Programme, as well as for sharing the experience of Japan’ s success in energy efficiency and conservation. We hope that this book will contribute to a greater understanding of Japan’s success in the increasingly important field of ener gy efficiency. I also would like to thank Mark Hong for coordinating the ISEAS Energy Programme and Agung Wicaksono for editing this book. K. Kesavapany Director, Institute of Southeast Asian Studies July 2007

1 Energy Efficiency and New Technology: Challenges and Problems in Exporting Japanese Energy Saving Technologies Makoto Nishimura and Ram Giri

At the Second East Asia Summit held in Cebu, Philippines on 14–15 January 2007, Japanese Prime Minister Shinzo Abe announced Japan’s intention to provide Japanese energy saving technologies to help Asian nations achieve efficiency in energy use and to reduce greenhouse gas emissions. The Prime Minister announced a US$2 billion aid package to help Asian nations develop energy saving technologies that can help to decrease the region’s dependence on oil. He also invited researchers and Japanese experts to come on board. These commitments from the Prime Minister himself show that Japan has highly ef ficient energy saving technologies and is commited to spread such technologies to other parts of the world. Before the “Oil Shock” hit Japan in 1973, the general view is that energy resources, especially oil, will not run out

of supply. In that year, a brief but serious panic occurred in Japan. The manufacturing of detergent and toilet paper had to be halted, and about half of the elevators in buildings had to be stopped to reduce ener gy usage. Television stations ceased their broadcasting at midnight, and car usage had to be decreased to save petrol. The year 1973 saw the dawn of ener gy conservation in Japan. Since then, many products, especially automobiles and household appliances, could only be sold if they have been proven to be energy saving (shoo-ene). Energy saving features are not restricted to general consumer products only but also to manufacturing facilities, transportation machines, houses, and buildings. Many Japanese products are now considered as a small package of ener gy saving technologies. Energy efficiency in Japan has improved by more than 37 per cent in the last thirty years (see Figure 1.1), and it has become the most energy-efficient country in the world.1 The Japanese Government has targeted a further energy conservation by 30 per cent in the next ten years (see Figure 1.2). Energy efficiency in the United States is half that of Japan, and in China it is is only one-ninth that of Japan (see Figure 1.3).2 If the whole world achieves the same level of energy efficiency as Japan, global oil consumption would go down by between one-third to half of 84 million barrels per day in 2005. At this rate, the peak out of oil reserves would be delayed by forty years, with a possibility to further extend it by another forty to eighty years. In the United States, a paradigm shift named “Katrina Shock” occurred in 2006. The shift occurred thirty years after it happened in Japan since the U.S. ener gy selfsufficiency rate is 63 per cent. The ratio in Japan is only 4 per cent. 3 See Figure 1.4.

In his 2007 State of the Union Address, U.S. President George W. Bush appealed for the introduction of sustainable energy and energy conservation. Among others, President Bush set a goal for reusable and alternative fuel production that is significantly higher than the goal set in the Ener gy Policy Act of 2005. However, it is believed that the United States is biased towards the production of biomass ethanol because of the following reasons: 1. to increase ener gy production in the country from an energy security perspective; 2. to execute its agricultural policy by providing incentives to farmers in the corn belt who support the Republican Party; 3. to promote automobiles that use biomass ethanol, which are produced by the Big Three automobile makers, in order to counter Japanese hybrid automobiles; and 4. to cope with the difficulty of constructing new gasoline refineries. It costs approximately US$20 billion to construct one new refinery, and the gasoline yield is only 50 per cent. In 1981, there were 325 refineries in the United States, and they produced 18 million barrels per day . In 2005, the number of refineries was only 148, which produced 17 million barrels per day (see Figure 1.5). 4 In terms of energy efficiency, developing a new energy source is equivalent to improving energy efficiency by energy conservation. It is comparable to making money through fund management, which is equivalent to returning a debt

and saving on the interest. However, people are more eager to create something out of nothing than to reduce something that is non-existent. For example, if the United States is concerned about ener gy security, they should encourage raising the temperature of air conditioners slightly or introduce car pooling. The wasteful consumption of energy by the United States and the increasing demand for ener gy in countries such as China and India will have a big impact on the world’s energy security. Many agree that Japanese ener gy conservation technologies should be made available to the whole world. However, there are significant issues to be addressed. First, energy conservation technologies that are established as products, such as hybrid cars, can be made available by producing, exporting and selling those car overseas. However, the hybrid car technology is an exception as most Japanese energy conservation technologies have not been commercialized. In addition, lar ge energy-conservation technologies are closely integrated to production technologies. In order to transfer the ener gy conservation technologies, the production technologies need to be transferred as well. There is a strong concern that transferring the production technologies would affect the competitiveness of Japanese companies. Therefore, energy conservation technologies need to be separated from production technologies. There are some ener gy conservation technologies that have been separated from production technologies and have been successfully commercialized, but the number is still very small. The English proverb “Rome was not built in a day” applies to Japanese ener gy saving technologies. These technologies come about from many years of improvements and experience.

An example of a Japanese energy saving technology in the production field is the well-known “Kanban” process. The Kanban process does not require stocking of goods but directly assembles more than 3,000 parts delivered just in time with precise inventory control. For some Japanese companies, there is an of ficial rule that a group of five members must submit an improvement proposal involving energy saving to their higher management every month; for a group of ten members the requirement is once every three months; and once a year for a group of thirty members. If their proposal is selected, the whole group including their family members are awarded with attractive incentives including overseas trips. The author had personally received such incentive when he was with a manufacturing company in the late 1980s. A group of thirty members had proposed an in-house ener gy-saving technique. In the system there were three spots to produce steam and eleven spots to use steam. The proposal was to reduce the steam-using stations from eleven to six and to reduce the distance of each station from the steam-producing station. After changing to the new layout, the company managed to save energy by 30 per cent by reducing heat loss and pump power consumption. When their proposal was selected, the thirty team members, including their families, were awarded with a two-week trip to Hawaii. This is an example of how Japanese manufacturing industries are promoting energy saving technology in each level of activity. Other than in manufacturing, many other Japanese industries have been developing their own inhouse energy saving technologies, which are the most efficient in the world. The strong support from the Japanese

Government has also promoted research and development (R&D) of these technologies. The government not only makes the policy but also provides financial support to newly developed ener gy saving technology . Almost all machineries and household appliances in Japan meet energy consumption efficiency standards. There are three standard value systems: (1) minimum standard; (2) average standard; and (3) maximum standard, also called “T op Runner Standard”. In other parts of the world, the minimum standard value system is the most popular standard. But in Japan, the maximum standard value system is the common standard. Another example of ener gy saving can be found at a metal wire manufacturing company . This company has reduced 37 per cent of its yearly ener gy consumption5 by controlling the circulation of cooling water , using highefficiency motors, adjusting the pressure of compressors, using high-efficiency lamps, reducing the number of lamps, adding sensors, and controlling the ventilation system. As mentioned earlier , the Japanese Government has targeted a further energy conservation by 30 per cent in the next ten years. To achieve this target, Japan has to focus on the energy consumption in of fice buildings. Nearly 80 per cent of the total ener gy consumption are from air conditioning, lightings and sockets. Many new ener gy saving technologies are being developed in order to reduce energy consumption in office buildings. For example, JFE Engineering Company has developed the clathrate hydrated slurry air conditioning system, which is capable of conserving energy in air conditioning systems (see Figure 1.6).6 The developed clathrate hydrate has latent heat over the temperature range of 5 to 12 degrees Celsius, and a

mixture of clathrate hydrate and aqueous solution (referred to as hydrate slurry) has greater cooling capacity compared with cold water . The utilization of hydrate slurry in air conditioning system is expected to reduce the consumption of pumping power substantially . This technology was originally developed as an in-house energy saving technology at a steel factory . It can be utilized to cut down power consumption of air conditioning by a maximum of 40 per cent. This technology has been introduced in Southeast Asia. An office building near Changi Airport in Singapore is experimenting the use of this new technology . The second reason for the dif ficulty in transferring Japanese energy conservation technology overseas lies in the countries receiving the technology . There are various hurdles, such as regulations, customs, and the attitude towards energy conservation. For example, in Singapore, there is a tendency to set the air conditioning in of fices to very low temperature. This leads to over-cooling the office environment. Even though the ener gy effectiveness of hydrated slurry has been proven, using the new technology involves investment in new plant and equipment. Needless to say, the investment could be easily recouped in a few years from lower power consumption and lower electric bills. However, building owners are not interested in new investment and additional construction work. As mentioned above, transferring Japanese energy conservation technology overseas requires an understanding about ener gy conservation by the countries and companies that receive those technologies. Therefore, a change of attitude towards energy conservation and engineering to physically introduce the energy conservation technology is required.

The third issue is who is to be financially responsible for energy conservation technologies. This issue is related to the issue of attitude. In the case of buildings, it is dif ficult to determine who benefits from energy conservation technologies — the owner or the tenants. It creates a dilemma when the payer cannot be ascertained. As has been shown above, it is not easy to transfer Japanese energy conservation technologies overseas. Nevertheless, some methods are under development. One such method is the Smart Of fice Environment System. 7 This system makes it possible for lights and air conditioning, which consume the most power in a building, to evolve from a dumb centralized system to an autonomously dispersed intelligent system. This newgeneration system conserves energy significantly, provides comfort to those in the building, and enhance of fice productivity (see Figure 1.7). It is a breakthrough system, considering the three effects of the system. In the Smart Of fice Environment System, a microchip that controls brightness is embedded into adjustable fluorescent lights and/or LED lights that are used in a building. Those working in the building will each be given a card-type photometer that contains information about their preference on the brightness of the lights. They can adjust the brightness by putting the card on their desk. The photometer controls the brightness of fluorescent and LED lights by detecting light coming out from computer displays and light coming in from windows. As a result, 40 to 50 per cent of electricity saving is possible. The control of air conditioning works on the same principle, but it achieves “personal air conditioning” by utilizing floor heating and an air conditioning system that is similar to a car air conditioner .

Incidentally, while doing research on the system it was found that air conditioning has more to do with perception than performance (see Figure 1.8). Coolness is felt when a person’s face feels cool, and he feels warm when his back and feet are warm. Even though the output of a car air conditioner is very small, coolness is felt in a car because cool air blows directly to the face. Using the same reasoning, a person will feel relatively warm if his back and feet are warm, even though his face is cold. This finding may not come as a surprise, but it that has bearing on the performance of air conditioning system. The reason that air conditioning in buildings may not feel cold even if it is set at 25 degrees Celsius is because it cools the feet, not faces. About 50 per cent of cold air that controls the temperature of a whole building to 25 degree Celsius is used to cool down ducts. The same principle applies to heating. Warm air is used to warm up ducts and ceiling, and people only get to enjoy the remaining warm air. With the Smart Of fice Environment System technology, those working in offices will experience optimum conditions with their preferred lighting and temperature levels. Changeable colour of lighting and slight breeze with air conditioning are also being developed. With these independently adjustable features, people will be able to work in more comfortable environment. This will lead to less stress and increased productivity.8 In other words, added value is created. Significant ener gy conservation can be achieved with the technology, but the challenge lies in selling the technology with added value as a sales point and consequently creating a business model to materialize ener gy conservation. If successful,

2 Energy Efficiency and Conservation Policies and Measures in Japan Yasushi Akahoshi

Introduction In previous years, the situation regarding regional economic cooperation and integration has been developing actively. One tangible development was the East Asia Summit (EAS), a 16 member-country cooperation. Two EASs or leaders’ meetings have been held, in Kuala Lumpur in 2005, and in Cebu, Philippine in early 2007. The Third EAS leaders’ meeting will take place in November 2007 in Singapore. There are several issues that the leaders have decided as possible fields for cooperation. Ener gy issues have been regarded as the most important, as shown in the EAS leaders declaration entitled “Cebu Declaration on East Asian Energy Security”. Singapore has been one of the most active countries for energy cooperation, and has proposed to host the First East Asia Energy Ministers Meeting, a move welcomed by the other leaders. This paper discusses the policy side of Japanese energy efficiency and conservation. Chapter 1 by Makoto Nishimura,

Executive Vice-President of the Mitsui Global Strategic Studies Institute, Japan, is on ener gy efficiency from a private business perspective. This paper is divided into three parts. The first part examines the situation on ener gy consumption in Japan as a brief background. The second part discusses ener gy conservation policies and measures. International cooperation for energy efficiency is discussed in the final part. The material for this chapter was mainly contributed by colleagues in Tokyo. Therefore, credits go to the Agency for Natural Resources and Ener gy of the Ministry of Economy, Trade and Industry (METI). The Present Energy Consumption in Japan Figure 2.1 compares ener gy consumption in three sectors from 1973 onwards, when the first oil shock took place. The figures in the second column indicate the amount of energy consumption in each sector , with the amount in 1973 taken as 100. The figure shows that the ener gy consumption in the commercial and residential sector and the transportation sector has been steadily increasing, as indicated by the number 247 and 212 respectively.Meanwhile, the industrial sector’s indicator has been almost flat. This does not mean that the ener gy conservation effort has been conducted only in the industrial sector . Energy efficiency in the other two sectors has been improving on an individual equipment base, while the impact of the increase of the quantity of equipment, such as automobiles and air-conditioners, has significant effect much beyond the compensation of such ef fort. Various factors might have

affected the levelling of energy consumption in the industrial sector, such as the recent recession in the Japanese economy. Nonetheless, credit should be given to the industrial sector for making a tremendous ef fort in energy conservation. Figures 2.2 and 2.3 show a more detailed breakdown of the statistics shown in Figure 2.1. Figure 2.4 compares the ener gy consumption in some countries. Japan has the world’ s lowest primary ener gy consumption per GDP. The figure shows that countries such as Russia, India, and China have much room for improving their energy efficiency, and as well as other countries in ASEAN, which would af fect the overall economic performance. The figure for Singapore is not shown in this chart, but it is 2.3. TABLE 2.1 Diversification of Energy Sources in Japan after Oil Crises (In percentages)

renewable energy, and has been stockpiling crude oil. As a result, dependency on oil has decreased from around 77 per cent in 1973 to 49 per cent in 2005, while share of other energies have increased in the same period, such as natural gas from 2 to 14 per cent, and nuclear from 1 to 11 per cent. Looking at the statistics in Figure 2.5, one of the efforts made after the oil crises was to reduce the dependency on the Middle East. However , that dependency , which had once declined, had increased again from the 1990s when domestic consumption in former oil exporting countries like China and Indonesia began to rise. Figure 2.6 shows the breakdown on trend of ener gy consumption in Japan in the industrial sector . As noted earlier, the energy consumption in the industrial sector has been generally steady since the oil crises. The major contributing factor has been the improving ener gy consumption intensity per index of Industrial Production for the manufacturing industry. Even though this intensity has been increasing slightly, Japan’s figure is much lower than other developed countries, as is shown in Figure 2.7. On the other hand, the ener gy consumption in the commercial and residential sectors has been increasing steadily as shown in Figure 2.8. Figure 2.9 shows the comparison of ener gy consumption per capita in major developed countries, and it indicates that Japan’s figure has been growing but it is still below other countries. Although the total ener gy consumption of commercial and residential sector has been growing, the energy efficiency on individual equipment base has improved dramatically . As Figure 2.10 shows, the energy needed for CRT television has been reduced by almost 50 per cent in twenty years, and

the energy for air-conditioners has been improved for more than 40 per cent in just ten years. One factor contributing to the increasing ener gy consumption is social change. As shown in Figure 2.11, the number of households has been increasing very steadily . Twenty to thirty years ago in Japan, it used to be very common for three generations to live in one household. However, the size of each household has reduced since many young couples prefer not to live with their parents.As such, the number of households has been increasing, and that has contributed to the growing ener gy consumption. Another factor for the increasing energy demand in this sector is the change in lifestyle. As shown in Figure 2.12, while many appliances have improved their energy efficiency standard, the number of appliances per household is increasing. As a result, energy consumption per household is rising. From my own personal experience, in 1973, when I was 8 years old, my apartment was not equipped with any air conditioner, and my family did not own a car . There was just one television for the entire family , but that did not mean that my family was poor. Nowadays, it is common for each room in a household to be equipped with an air conditioner and a television set, and for one family to have more than two cars. Even college students can af ford to own a car. The improving standard of living has definitely contributed to the increase in energy consumption, and the decisive factor for more ener gy saving lies in these areas. It should be noted that in the residential sector, standby power consumption is not negligible; it is as high as 7 per cent of total consumption. Therefore, the measure to deal with this issue would be indispensable.

Figure 2.14 shows the trend in the transportation sector. Energy consumption in that sector had increased even after the oil shock, but has levelled of f in recent years. Figure 2.15 shows that the expanded energy consumption in the transportation sector could be attributed to the increasing number of private passengers vehicles, even though energy consumption intensity is relatively low compared with other transportation. Energy Conservation Policy and Measures The energy conservation policies and measures in Japan consist of some elements, the core of which is the Ener gy Conservation Law, its literal translation from Japanese is “the Law concerning the Rational Use of Energy”. This law and other supplementary measures comprise the whole policies and measures. The preceding section examines the overall situation on energy consumption in Japan, by looking at three sectors: industrial, commercial and residential, and transportation. The Energy Conservation Law was originally designed for factories, but it has been expanded to include other sectors such as commercial and transportation sectors. For the residential sector and private vehicles in transportation sector, it is dif ficult to place such a wide range under government regulation. Therefore, various complementary measures have been planned and implemented. The basic concept of the Ener gy Conservation Law is illustrated in Figure 2.16. Factories and business establishments that have high ener gy consumption are designated as “Type 1”, and those with medium consumption

as “Type 2”. The current thresholds are annual consumption of 3,000 kl in crude oil equivalent for Type 1 and 1,500 kl for Type 2. Once factories or business establishments are so designated, they have to appoint qualified persons for energy management. The factories classified in Type 1 have to appoint licensed “ener gy managers”. Those factories or business establishments then have to submit periodical reports on its energy usage. They also have to submit medium and long-term plans for measures to achieve ener gy conservation targets. As shown in the flow chart in Figure 2.17, for Type-1 factories or business establishments, the government conducts on-site investigation or factory inspections to check if they meet the standards. If the results of assessments are below the threshold, they have to prepare and submit a rationalization plan, then implement the plan, and take other relevant steps. If they are deemed to be extremely insufficient against the set criteria, the government will then disclose the factory’s name and issue an order . The Energy Conservation Law is a regulatory measure. However, the regulation or restriction is one-sided and insufficient. Therefore, the government provides “incentives” to support the effort towards energy efficiency in the private sector. For example, the government supports: (i) lar gescale and joint energy saving efforts such as petrochemical industrial complexes, (ii) the installation of the industry’ s first model plant for highly ef ficient plants, and (iii) the installation of highly ef ficient industrial furnaces, whose energy saving ef fect is more than 30 per cent, thanks to waste-heat recovery mechanism and so on (see Figure 2.18).

Figure 2.19 illustrates a well-known system for ener gy improvement in Japan, called Top Runner Program under the Energy Conservation Law. This program was introduced in 1998 and is applicable to home and of fice appliances as well as to automobiles. Taking automobiles as an example, the basic concept is to set the standard of ener gy efficiency at the best performer currently available in the market. In this example, the standard is set at 16 km per litre. Secondly , a target year is set and all manufactures are required to meet this tar get. Eventually, it can be expected that even the worst ener gyefficient automobile’s performance would meet the tar get of 16 km per litre. At present, twenty-one items are designated under this program, as shown in the list. The Top Runner Program aims to urge manufacturers to accelerate their efforts to compete with their rivals in terms of energy efficiency. The target year, which has been set differently for each item, has already been surpassed for some items, and many items have achieved the outcome beyond the tar get initially set even earlier than the tar get year (see Table 2.2). To further illustrate, Figure 2.20 shows the improvement in energy efficiency of automobiles. In 1999, the tar get for automobiles in the Top Runner Program was set at 2010. In 2004, the average fuel needed for 1 km was 15 litre, compared with the 12.1 km per litre in 1995, which was the “base year” for automobiles, and it was a 22 per cent improvement. Again, the target year is 2010. However, almost 80 per cent of automobiles had already achieved the ener gy-efficiency target for 2010 in advance, as shown in the figure.

Next, there is another measure for ener gy-efficiency in the households sector . It is called the Ener gy-Saving Labelling System.1 For the thirteen assigned products, such as air conditioners and fridges, manufacturers are required to label their products to show whether and how the product achieves or fails the target set in the Top Runner Program. This allows consumers to easily identify and compare products in terms of energy efficiency, which would affect the utility costs that they have to pay. High performers can use green labels, while lower performers have to use red labels, which might seem a little harsh for them. The labels on the left in Figure 2.21 are for display by retailers, and the one on the right is an example of a label attached to the unit itself. In 2006, the Uniform Energy Saving Label for retailers was introduced. Retailers are now required to provide accurate information in their stores in a uniform manner . In this system, energy-saving performance is indicated by the number of stars. The label also indicates the utility cost in Japanese yen. In this example, the consumer who buys this product has to pay roughly 9,900 yen per year (see Figure 2.22). Figure 2.23 shows appliances that have been designated the uniform labelling system. A system called Energy Efficient Retailer Assessment System was also introduced in 2003. This is the system for evaluating retailers instead of products.This system is based on the idea that retailers play an important role in ener gyefficient efforts. This system targets retailers whose sales of home appliances account for 50 per cent or more of total

sales. METI recognizes retailers who actively promote energy-efficient products or provide appropriate ener gy conservation information. Those retailers may display the logo shown in Figure 2.24, which states “excellent retailer who promotes energy-efficient products”. It is earlier stated that standby power consumption is not negligible. In order to reduce such consumption, voluntary programmes have been conducted by relevant industry associations, such as that of the electronic and gas industry, as shown in Figure 2.25. High-efficiency equipment are also being promoted in Japan. Taking into consideration that ener gy demand for hot-water supply comprise almost 30 per cent of total energy consumption in a household, the introduction of energy-efficient hot-water supply system, such as the HeatPump Boiler which has 30 per cent ener gy-saving effect, is promoted (see Figure 2.26). High-ef ficiency air conditioning systems as shown in Figure 2.27 are also being promoted. Regulation measures in the Ener gy Conservation Law are also applied to residential and building sectors, and the application was strengthened by the amendment. In such cases, METI cooperates with relevant agencies and local governments. In the past, only lar ge-scale buildings are governed by the regulation, but now it is also applied to large residential construction. Those who intend to construct, extend, or repair extensively these types of buildings have to submit their plan for ener gy conservation to local governments, and if they are regarded as insuf ficient, administrative instructions shall be given (see Figure 2.28).

In such cases, besides the regulation, we provide promotional measures to improve the ener gy efficiency in houses and buildings. We have a programme called “Government program to foster the introduction of high efficiency energy systems in houses and buildings” as shown in Figure 2.29. There are energy-management systems utilizing IT. Such systems for homes are called Home Ener gy Management System (HEMS). The system for buildings is called Building Energy Management System (BEMS). A new business called Ener gy Service Company (ESCO) offers comprehensive services on ener gy conservation to their clients, and the clients pay a part of their energy saving gain, such as savings on utility bills. As shown in Figures 2.30 to 2.32, the ESCO market has been growing since the mid-1990s, and it has reached almost 50 billion yen, which is equivalent to US$400 million. The government promotes such kind of business by partial subsidies and low interest loans. METI also had a contract with one ESCO service provider for METI’ s building in order to accelerate the usage of ESCO in public sectors. It pays 20 million yen for a four-year contract and the contractor guaranteed the minimum reduction of 5.5 million yen per year . Figures 2.33 and 2.34 show ener gy conservation measures in the transportation sector . The regulatory measures are similar to those for the industrial sector . Transportation business operators, as well as other business operators who act as consigners, are subject to the regulation. They have to submit their energy saving plans and periodical

• Energy in houses and buildings is effectively saved by the comprehensive introduction and utilization of highly heat insulating buildings, high-efficiency equipment and appliances, and energy management systems. • Therefore, highly-motivated efforts to introduce multiple "high-efficiency energy systems" are supported with an aim to promoting wide use thereof in a wide range of applications. • As for houses, in particular, it is important to make the functions and advantages of highly energy-saving houses known widely to consumers. For this purpose, studies are now under way in a direction to effectively utilizing budgetary measures by evaluating higher performance in a suitable and appropriate manner and enhancing the collaboration with the program to visualize such performance.

reports to the relevant ministries. If these are regarded to be insufficient, they will be given some advice, and if the advice is not followed through, measures such as disclosure of names or fines may be applied. Relevant ministries, METI, National Police Agency, Ministry of Land, Infrastructure andTransport, and Ministry of Environment are also promoting eco-driving, which could have a 25 per cent ener gy-saving effect. We have also been promoting cars with the “idlingstop” system that can improve fuel economy by almost 10 per cent, through subsidy and other measures. Japan has also introduced the “automobile greening tax”, which reduces the burden on the purchaser of automobiles with excellent fuel-economy (see Figure 2.35). Measures such as Electronic Toll Collection (ETC) have been promoted as one of the tools for energy conservation. The Government of Japan published a New National Energy Strategy in 2006. The target for energy efficiency is at least 30 per cent improvement by 2030. Based on this strategy, METI has prepared a Strategy for Ener gy Conservation Technology. This strategy focuses on five priority fields, such as energy conservation technology for living space or technology for advanced traffic society. The budget will be distributed according to its priority in the strategy . The government is promoting the development of energy conservation technology in many ways and spends almost 50 billion yen, equivalent to US$400 million, per year .

International Cooperation for Energy Efficiency and Conservation Figure 2.37 shows the projection by the Institute for Energy and Economy of Japan (IEEJ). According to their Asia/ World Energy Outlook 2006, the ener gy demand in Asia would grow rapidly by 2.8 per cent per year up to 2030, compared with 1.7 per cent for world and 1 per cent for North America. Therefore, Asia will use up nearly twothirds of world’s energy demand in 2030, while the figure in 2004 was only half of world’ s demand. Among the Asian countries, growth of ener gy demand from India and China are expected to have the most significant impact (Figure 2.38). From 2004 to 2030, while Asia’s increase would be twofold, China’ s increase would be 2.1 times and India’s would be 2.9 times. Energy intensity per GDP indication, compared with Japan set as 1.0, are 18 in Russia, 9.2 in India, and 8.7 in China (Figure 2.39). Figure 2.40 shows the progress in ener gy conservation in Japan from a different perspective. The growth in energy consumption in Japan remains at a low level compared with its economic growth. Figure 2.41 shows the dif ferent perspective for ener gy consumption. The energy intensity, shown as a figure of ton-oil equivalent divided by billion yen, has improved 37 per cent over the last thirty years. Japan believes that the cooperation in energy efficiency and conservation should be the main focus of cooperation in Asia, and it has been very aggressive in promoting the widespread use of Japan’ s advanced ener gy-saving

technology. In that context, Japan supports the capacitybuilding of Asian countries in the ener gy efficiency and conservation field by dispatching experts and accepting trainees. Dispatched experts provide information and lectures on Japan’s energy saving technology, legal system, among others. Invited trainees study Japan’s energy saving efforts and visit energy saving facilities (see Figure 2.42). The New Energy Development Organization (NEDO), a semi-governmental or ganization, has been conducting projects by which Japan transfers its ener gy-saving technology into Asian countries. Examples of these projects are shown in the right-hand-side of Figure 2.42. China’s surging energy demand will af fect the world energy balance. Therefore, the need for energy efficiency is most critical in China. Last year, Japan held a Japan-China Energy Conservation and Environment Forum, whereby both government officials and private sectors exchanged a wide range of opinions regarding energy and environment. Both sides have agreed to continue such dialogues in the future. Following the forum, the cooperation between the two countries has been developing in various ways, which include training and sending missions, at both governmental and private sector levels. Both sides also agreed to establish the Policy Dialogues between Japanese and Chinese Ener gy Ministers and to implement some model projects in the energy conservation and environment fields (see Figures 2.43 and 2.44). It is expected that energy demand of India and ASEAN countries would continue to grow . Under such situations, ASEAN countries and India are now addressing ener gy

conservation, and Japan is also willing to support such efforts through various measures (see Figures 2.45 and 2.46). According to IEEJ projections (Figure 2.47), there would be room for energy reduction of 15 per cent or 940 million ton equivalent in Asia in 2030, if we can take advantage of the energy saving technology. This is 1.8 times the scale of Japan’s current primary energy demand. The Government of Japan published the New National Energy Strategy in 2007. Based on the strategy, METI also formulated an Asian Energy Efficiency and Conservation Program, by which Japan strengthens the support for Asian countries in this field (Figure 2.48). In conclusion, we note that the Second EastAsia Summit in Cebu in January 2007 discussed ener gy as the most important issue (Figure 2.49). At the summit, Japan’s Prime Minister Abe proposed the cooperation plan named “Fuelling Asia-Japan’s Cooperation Initiative for Clean Ener gy and Sustainable Growth”, which was welcomed by other leaders. It contains cooperation measures including biomass energy and clean use of coal, but the ener gy efficiency and conservation is top priority, as shown in Figure 2.50.

Singapore government’s National Environmental Agency (NEA) also sets up a “green” label as a mandatory requirement for air conditioners and refrigerators starting January 2008. The scheme was actually introduced in April 2002, but so far only about 20 per cent of those appliances have been labelled. This is in line with steps taken in other countries such as Australia, China, and United States, apart from Japan. (“ ‘Green’ labels a must for air -cons, fridges”, Straits Times, 30 June 2007.)
