World Energy Outlook

Energy consumption is known to be growing rapidly in regions such as Asia, where in recent
years of strong economic growth. According to IEA statistics (see Fig. 1
use of fossil fuels (see Figure 3), which will have a significant impact on
climate change on a global scale.

Meanwhile, in the long term, energy supplies will gradually decline,
as crude oil prices are rising and have already exceeded $90 per barrel, and in
In the future, the upward trend in energy prices can only strengthen. Also calls
the concern is that fossil fuels will be depleted.

Therefore, effective
the use of energy is one of the most important measures in terms of ensuring sustainable
economic development. The IEA is considering measures to reduce CO2 emissions and
energy conservation as parallel processes, since both imply
a number of activities in relevant sectors (see table 1), and Japan implements almost all of these
recommendations regarding technologies, equipment, products, etc., most of which

presented energy situation in Japan

In the 1970s, Japan experienced an oil crisis amid political instability in
Middle East. Not only industrial, but also private and municipal residential sector
joined forces in the direction of the use of new energy technologies.
Active work on new technologies has made it possible to create equipment, technologies and
earned across the country.

investment incentive programs when energy prices were high. As a result, in
over the course of about 15 years, starting in 1973, the country was able to double its GDP without increasing
dissemination of such energy-saving technologies. Its GDP to date has grown by 2.3
times compared to 1973. At the same time, the growth of energy consumption was restrained and the current
the level is only 1.3 times higher than in 1973. In particular, energy consumption in
the industrial sector decreased by 0.85 times (see Fig. 4).n this Products and Technologies catalogue.

If the situations described above are considered in terms of changes in Japan’s GDP in
compared with primary energy consumption (Fig. 5), it can be seen that more than 35% improvement
was achieved after the oil crisis, with energy saving activities
continues. The Goods and Technologies catalog introduces the reader to new technologies,
which have enabled Japan to make huge strides in building an energy efficient

Industrial Sector Energy Efficiency Analysis (1) Overall

On fig. 6 compares energy efficiency levels across industries
industries in different countries. Japan has reached the highest world standards
energy efficiency in almost all industries. It can be said that
high levels of energy savings have been achieved as a result of implementing high
energy-saving technologies, including those described in this Products and

stations, replacement of equipment and other innovations, the country as a whole will be able to receive a large
energy saving effect.
Assuming Japan’s electricity generation efficiency is 41%,
and in another country – 33%, then the country after the implementation of Japanese technologies will be able to reduce input
new power plants by about 80% of those previously planned. The country can also
reduce coal consumption by up to 80%.
Electricity companies in Japan provide consulting services for
building master plans, maintenance and fuel management
power plants. The examples described in our Products and Technologies catalog will allow
efficient use of your country’s fuel generating capacity.

efficient use of thermal energy. Many of them are described in this book – cogeneration,
waste heat recovery, high-efficiency blast furnaces, boilers,
efficient use of steam. In industrial processes that consume fuel and
heat energy.

the level of waste energy is high, so high energy-saving
the effect can be realized with the help of technologies that reduce thermal energy emissions,
or technologies that extract secondary thermal energy. Moreover, such technologies
favorably affect the state of the environment. In view of the foregoing, the introduction of these
technology happened quickly. They can be used not only in new facilities, but also in
as part of the reconstruction of existing production facilities.
On fig. 8 and 9 show some examples of the dynamics of the use of industrial
high efficiency cogeneration boilers.

Energy efficiency analysis in the commercial and residential sectors

As can be seen in fig. 4, energy consumption has grown rapidly since the second half
1980s, both in the commercial and residential sectors due to improved quality of life and
deployment of commercial activities in new sectors of the economy.

Politics called
“Best Energy Efficient Products Program” has made a great contribution to
development of these sectors. Were developed and supplied to the domestic market household
energy consumption in these sectors has been contained for about 15 years. Row
products with efficiencies above this upper standard level are presented in our catalog

energy transfer for heating, cooling and refrigeration equipment. She is sometimes called
heat pump because it transfers thermal energy. Japan gave a huge boost
the development of highly efficient heat transfer technology by applying it to air conditioners,
refrigerators, water heaters and other devices.

On fig. 10 presented results
the use of energy-efficient household air conditioners that do not use
only heat transfer technology, but highly efficient control system using
transducers operating with respect to environmental measurement data, including
temperature. Such air conditioners are prevalent throughout Japan. On fig. 11 comparison is made
