To make petroleum consumption efficient in Malaysia, cooperation survey was conducted for the purpose of finding out needs for energy conservation and environmental technology and giving technical cooperation. Malaysia reserves oil and natural gas, and exports a part of them. To get rid of petroleum dependence, Malaysia started to give priority to natural gas, coal and palm oil as energy, and the rate of petroleum in the domestic energy demand reduced from 71% in 1985 to 60% in 1990. However, utilization by energy source is unbalanced, and promotion of efficient petroleum consumption and energy conservation/environmental technology is not sufficient. Policies for energy conservation and environment have just started on a national level, and it takes a little time to make them diffuse to individual enterprises. For this, required are promotion systems, training of engineers, PR campaign, recognition and establishment of the system of energy saving equipment. Facilities and equipment in energy multi-consumed sections are old-fashioned, and subjects in question are promotion of efficiency and measures taken for environmental protection. It is necessary to make a continued concentrating survey in these sections. 5 refs., 3 figs., 5 tabs.
