Use energy efficiently and economically
(Baonghean.vn) - Using energy economically and efficiently to meet the energy demand for socio-economic development is an important goal in implementing the national target program on economical energy use...
As a province with a large area and large population, the annual electricity consumption in Nghe An is quite high and increases rapidly over the years. According to statistics of Nghe An Electricity Company: In 2007, the whole province consumed 1,063,090 kWh, in 2008 it was 1,171,296,090 kWh (increased by 101%/2007), in 2009 it was 1,314,471,911 kWh (increased by 12.2%/2008), in 2010 there was a severe power shortage due to drought but still consumed 1,201,903,205 kWh, in 2011 it consumed 1,485,700,000 kWh... Along with that, the annual electricity loss is large (in 2007 it was 8.37%, in 2008 it was 7.7%, in 2009 it was 9.21%, in 2010 it was 11.65%, in 2011 it was 11.65%). is 10.75%).
The aluminum glass door production line at Austdoor company helps businesses save tens of millions of dong in electricity bills every month.
Faced with that reality, in order to use energy economically and effectively, in recent times, our province has focused on enhancing the role of state management in the field of electricity use, while actively promoting and raising public awareness to use energy economically and effectively; supporting manufacturers of energy-saving products to bring products to businesses and people; using energy economically and effectively in buildings and transportation activities.
Thanks to that, in 2011, although the number of enterprises with large electricity consumption in the area increased with about 135 production and business establishments using 500,000 kWh/year; 137 administrative units using 50,000 kWh/year, 279 lighting works using over 1,500Wh/year,... but with the efforts of the whole province, especially key energy-using enterprises, the whole province saved 16.3 million kWh of electricity and equal to 1.27% of the commercial electricity output of the whole province in 2011. Thanks to that, the electricity supply situation in 2011 was much better than expected, contributing significantly to the overall development of the province.
Also through this program, many businesses have proactively improved techniques, increased productivity and saved electricity. For example, at Austdoor Nghe An Joint Stock Company - Nghi Phu Small Industrial Park. To save energy, the company has invested about 50,000 USD to equip a synchronous production machinery system. Thanks to that, although the production lines always operate at full capacity, the company only has to pay about 6 million VND for electricity each month (about 1/3 compared to other production units in the same industry). In parallel, during these summer days, the company often sprinkles water on the roof of the production area to cool the air and increases production shifts during off-peak hours to limit electricity use.
Although certain results have been achieved, in many enterprises, due to being established for a long time, the equipment and machinery are old, outdated, and have low efficiency, thus wasting and inefficiently using energy; Buildings are increasing, but many buildings are designed and constructed without paying attention to the use of natural light, so they waste electricity.
In the current situation, the public lighting system still mostly uses energy-consuming light bulbs that have not been replaced by energy-saving light bulbs. No lighting projects using solar energy have been implemented, most people are not interested in saving energy, and the awareness of saving electricity among the people is not high, including officials and civil servants. There is still a situation of not turning off the lights when not in use, using electrical equipment such as air conditioners, water heaters, etc. inappropriately.
To solve this situation, there must be many long-term solutions on a province-wide scale. In particular, in addition to strengthening state management, the province will implement a program on economical and efficient energy use through the model of "economical and efficient energy use in each household", promoting, mobilizing, and guiding households in designing and building houses that can take advantage of natural light and ventilation; using insulation materials, energy-saving household appliances; increasing the use of vehicles and equipment using renewable energy... Popularizing high-performance, energy-saving equipment, new forms of energy, renewable energy, bio-energy, gradually eliminating low-performance equipment. Using energy economically and efficiently in production and business establishments, in construction and public lighting, in agricultural production...
It is expected that in 2012, the province's highest electricity usage capacity will be 200 MW, 10% higher than in 2011, and the expected output will be 1.57 billion kWh, nearly 140 million kWh higher than in 2011. Therefore, using electricity effectively and economically is still an important solution to ensure electricity supply for socio-economic development needs.
