Electricity waste is mainly due to equipment.

The shortage of electricity for economic development is becoming increasingly severe. Increasing electricity prices is considered a “leverage” for business owners to save electricity, but in reality, this scenario does not happen exactly as expected.

According to the Ministry of Industry and Trade, after 5 years of implementation, the energy saving program has attracted 40% of key energy-using enterprises nationwide to participate, building a model of efficient and economical electricity use. However, the results are still very modest.

The potential for energy savings, in the industrial sector alone, is quite large. Calculations show that textiles can save 5-15%, cement 10-20%, chemicals more than 20%, civil construction and transportation can save 25-30%...

The Ministry of Planning and Investment, the Ministry of Industry and Trade and the Vietnam Electricity Group (EVN) have repeatedly warned about inefficient use of electricity. Due to inefficient use of energy, to increase GDP by one percentage point, Vietnam's electricity production growth rate must be doubled or even higher.

A recent study conducted by ABB (a company specializing in manufacturing and supplying motors and electrical systems headquartered in Zurich, Switzerland) also showed that up to 60% of manufacturers have not invested in improving the energy efficiency of basic machinery and equipment in the past three years.

There are three barriers preventing businesses from investing more in energy efficiency. These are: business executives citing a lack of clear financial policies for energy efficiency investments, lack of information, and lack of energy efficiency solutions.

In reality, saving electricity in businesses only revolves around using compact light bulbs, turning off lights when not needed, and recently some ideas about energy-saving building models... without touching much on areas that consume large amounts of electricity, such as electric motors.

According to a recent study by the International Energy Agency (IEA), motors consume the most electricity, accounting for about 45% of global electricity consumption, followed by lighting at 19%. The agency believes that if the problem of inefficient, oversized or unnecessary motors can be solved, it is entirely possible to save 20-30% of total motor electricity consumption.

“It is surprising that motors account for two-thirds of the electricity used in industry, and the annual cost of electricity to operate an industrial motor can be as much as seven times its purchase price,” ABB research said.
