Promote efficient use of energy

Mùa khô năm 2010 chứng kiến sự quá tải của các nhà máy thủy điện khi thời tiết khô hạn.
Economic development requires a relatively large amount of energy has put pressure on the electricity sector while the energy wasted in the process of people use is not eliminated.

According to experts, Vietnam is in the top of the energy consumption is relatively large compared to the region and the world. In the period 2010-2020 energy demand in Vietnam will be increased 3 times.

Energy intensity of the continuous rise Vietnam

According to the report of the experts in meeting common law use of energy saving and efficiency by the Ministry of Trade and Industry held on 30/11/2010 in Hanoi, in the period 1999-2006, energy use in our country has increased by 12.4% per year while only 7.2% of GDP. Coefficient of elasticity between energy use / GDP is 1.7. Energy intensity of economy 387kgoe/US Vietnam increased from $ 1,000 of GDP in 1998 to 569 kgoe / U.S. $ 1000 of GDP in 2006 (constant 2000 prices).

Energy consumption per unit of product in many industries in our country is much higher compared to developed countries. Energy intensity in industry in Vietnam higher than Thailand and Malaysia, about 1.5 to 1.7 times. Between the growth rate of energy demand compared with the country's GDP growth to nearly 2 times, while in developed countries this ratio is below 1.

The experts, industrial growth is one of the main factors increasing the energy intensity of Vietnam. Industrial energy use in recent years has increased from 3.6 million TOE in 1998 to 12.3 million TOE in 2006 - only 3 times in the past 8 years.

In 1998, industrial countries accounted for one third of energy use, last but by 2006 accounted for 45%. Energy intensity of industrial production increased from 129kgoe / 254kgoe 1998 to $ 1000 / $ 1000 in 2006 (in constant prices of 2000). Rapid increase of energy intensity is due to the contribution of industries with high energy intensities, such as cement and steel industries grow faster than low intensity.

Energy consumption in the residential blocks has increased faster than GDP with an average speed of 11.5% annually in 1999-2006 period, contributing to the growth of energy intensity.

Electricity accounts for more than 70% of total energy consumption in the family. Growth in electricity consumption reached 10.2% in the same period, partly because rural network was expanded but mainly due to the significant growth of demand for lighting and appliances.

Many barriers in energy use

According to statistics, total electricity demand per capita kWh / person in Vietnam in 2006 is 656 kWh per person, higher than some countries in the region such as Indonesia, less developed countries such as Korea, China and the increasing. Electricity consumption in 2006 the average household in Vietnam is 245kWh/dau people, higher levels of developing countries. Moreover, people are not aware that improving the use of electricity in households and offices also waste significant. This makes energy supply more difficult, causing big pressure for the power sector especially in the dry season.

According to the Ministry of Construction, the total floor area of commercial buildings and residential high-rise growth rate of 6-7% per year. During the investigation shows that about 95% of commercial buildings and high-rise housing built in Vietnam, not the efficiency of energy use in the basic design and operation of the facility.

The studies and calculations show that potential energy savings in industry, cement, steel, porcelain, fisheries, consumer products .. in our country can reach over 20% field of civil construction, transportation can reach over 30%, manufacturing sector service activities are also potential savings are not trivial. Needless to say, consumption of industrial and consumer protection are the two major electricity users in Vietnam, of which industry accounted for 48% while 43% of civil total consumption.

Degree of depletion of energy resources that we must consider alternative energy, renewable energy to ensure energy security. According to calculations by experts, the world average of 41.4 more years we will run out of oil, 60.3 years, depletion of natural gas and 117 years of coal resources will be exhausted. Uncertainty of the world's energy depends mainly on politics, wars and conflicts around the world. So experts believe that investment in energy efficiency is much cheaper compared to invest to develop additional energy supplies. If Thailand, for Electrical 1kWh to invest about U.S. $ 2 cents, Vietnam needs to invest 4-6 cents for coal, oil, while saving energy consuming only one third to half of the first This investment in the plant.

Energy use efficiency savings to be institutionalized by law

Use energy-saving and efficient service of economic development and social policy is one of the top priorities of the Party and State. Law on energy saving and efficiency were 12 National Assembly adopted on 17/06/2010 and is effective from 01/01/2011. Law 48 of 12 chapters of regulations on energy saving and effective policies and measures to promote energy saving and efficiency; rights, obligations and responsibilities of organizations, households individuals in the use of energy saving and efficiency.

The Act also specifies the implementation of energy labels for electric appliances products to market before. 2012 will begin labeling for appliances, lighting, air conditioning, refrigerator, electric water heaters, electric fans .. In 2013 will be mandatory labeling for industrial products, electric motors, boilers, small and medium-sized, three-phase transformer .. In 2014 will be mandatory labeling of office equipment such as photocopiers, computer power supplies, commercial refrigeration cabinets .. 2015 will implement mandatory labeling of products with RE equipment and materials.

According to Hoang Mai, professional office management plan, the Institute of Technology under the Ministry of Trade and Industry, the "Law on the introduction of energy saving and efficiency in life is essential. Thereby, promote action, awareness of each person, each agency or production units to contribute to concrete actions to save energy. Himself as a woman in my family will also guide the family, friends and other people use daily to ensure electricity saving lives, reducing spending. "

At the Summit common law use of energy saving and efficiency, Mr. Nguyen Dinh Hiep, director of the Department of Science & Technology, Ministry of Trade and Industry said that the responsibility of the Ministry of Trade and Industry is very big in management, urge units according to law enforcement. The Ministry will coordinate with other ministries concerned to answer questions as well as to acquire the exchange to the Law on energy use and efficiency into the life and many people welcome.

Use energy saving and efficiency is the application of management measures and techniques aimed at reducing losses, reducing energy consumption of vehicles and equipment while ensuring the needs and objectives set for with the production and life.
