Vietnam’s Energy Efficiency Outlook
In 2011, total final energy consumption in Vietnam was about 85.6 billion kWh, increasing 400% compared to energy consumption in 2001.
Vietnam’ emission increased 376% from 5.8 million metric tons of carbon in 1990 to 27.8 tons in 2005, ranking first in CO2 emission worldwide between 1990 and 2005.
Energy consumption in Vietnam is forecast at 451TWh by 2030 of which energy consumption of industry sector accounts for more than 50%
In the last five years, Vietnam has started to import steam coal and oil products for its energy need. Continued GDP growth, increased foreign investment, and industrial growth are expected to triple energy demand in the next decade
In order to meet the growing power demands and to ensure a sustainable economic growth, Vietnam indeed needs to invest in energy efficiency.
The law on energy efficiency and conservation took effect in 2011 requiring major energy users to apply energy management systems => creating a concrete legal framework for energy efficiency and conservation activities.

Energy Consumption in Food Processing Sector
Food sector overview
Vietnam’s food-processing industry comprises around 260 seafood-processing plants (mainly for export), 24 slaughter houses and meat-processing plants, 160 beverage plants, 65 fruit- and vegetable-processing plants, 27 plants manufacturing instant noodles and 23 confectionery manufacturers.
Common types of energy used in the sector is electricity and fuel, of which electricity is consumed the most.
Equipment that consumes much energy include: HVAC (heating, ventilation, and air conditioning), freezing machine, ice maker, cold storage, pumps, fans and other electrical motors.
A majority of Small to Medium Enterprises (SMEs) is using outdated and inefficient energy equipments, either the boiler, heater, refrigerator, or lighting system such as high-pressure mercury lamp, incandescent and T10 fluorescent light bulbs. Many steamers have leaking issue.
Electricity 45%
Coal 21%
Oil 29%
Water 5%

Garment sector overview
Garment industry is a key sector and the largest employing sector.
There are about 2400 textile and garment manufactures in Vietnam that employs almost 2 million people, of which there are about 1500 garment companies.
Vietnam’s textile and garment industry earned about 15.6 billion US$ export turnover in 2011 and currently accounts for 2.5% of the total global garment market share and is the fifth largest textile and garment supplier in the world
Energy and water cost at Vietnamese garment companies is higher compared to other Asian countries. Energy cost to produce same products is 1.5-1.7 times higher than that in Thailand, China, Malaysia. Water amount used in dyeing is 3 times higher than that in Japans
Energy waste is up to 30% due to old technologies and outdated energy management systems. Approximately 50% of the equipment of garment industry of Vietnam has been used for over 20 years

Food Sector
Energy saving potential for food processing industry is up to 20%
EE motors and variable speed drive (VSD) are promising products.
The market size for EE lighting and EE equipment such as freezing machine, ice making machine, boiler…; insulation materials; inverter; heat pump; solar water heater are expected to be high.
Garment Sector
Energy saving potential for garment industry is up to 30%
Energy cost accounts for 10-15% of production cost whereas energy waste is up 20-32% due to old technologies and outdated energy management systems.
EE motors and variable speed drives are promising products as SMEs are willing to invest.
The sewing saver also has a lot of potential
