contribute to
the sound development of the national economy through
implementing necessary measures for the rational use of energy
in factories, buildings, transportation, and machinery and
equipment, to comprehensively promote the rational use of energy,
while it seeks to ensure the effective utilization of fuel resources that
would meet the economic and social environment of energy

the Electric power consumption of a city hotel in 2009 and 2010.
It is easy to understand the drastic improvement in 2010 compare to 2009. In
this hotel ,the energy manager made an energy conservation team to reduce
energy consumption in 2009. After the action， they could reduce 10% electric
consumption.

Summary
(1) The EC Law of Japan has been played very important roles to
promote energy efficiency and conservation, and to achieve great
improvement.
(2) The methods of the EC Law are closely related to the management
in the manufacturing factories and the workplaces.
(3) The experience and the method of Japan for energy efficiency and
conservation under the EC Law is a very useful knowledge for the
countries
