The significance of energy conservation and emission reduction

The significance of energy conservation and emission reduction

In recent years, severe typhoons, sandstorms, high temperatures and droughts, and extreme precipitation have occurred frequently worldwide, causing increasingly serious harm. The most important and undeniable reason for this is the global climate change caused by excessive consumption of carbon based fuels - extreme weather is just a reflection of energy consumption.

A survey by the Chinese Academy of Sciences shows that China is one of the countries with the most severe natural resource waste in the world, ranking 56th out of 59 surveyed countries. According to statistics, China's energy efficiency is only 26.9% of that of the United States and 11.5% of that of Japan. Therefore, promoting energy conservation and emission reduction is urgent.

It is reported that industrial production, which accounts for more than half of the country's energy consumption, especially the electrical equipment manufacturing industry, has an unfavorable energy usage situation. Although we are constantly phasing out outdated equipment and technologies to improve energy efficiency, a large number of inefficient technologies still exist widely in our manufacturing plants.

Our country has over 500 million kilowatts of electric motors, which consume 80-100 billion kilowatt hours of energy annually, accounting for 75% of industrial energy consumption and 60% of total energy consumption. Among them, 70% of the motors used to drive blowers and electric pumps, with a total output of 250 million kilowatts, should use variable speed drive. But the fact is, only 20% use variable speed drive - a huge waste of electricity goes without saying.

In the 11th Five Year Plan, the Chinese government prioritizes energy efficiency. In the next 15 years, China will be more committed to transforming itself from a current inefficient energy user to an efficient energy user. But improving the current energy consumption situation requires unremitting efforts from multiple industries, including electrical equipment, coal, petroleum, and construction.

Reducing energy consumption is the responsibility of the electrical equipment industry. While phasing out outdated equipment, enterprises should also draw on advanced management experience and technology from abroad. With the help of Rockwell's automation solutions in the power generation field, Weihai Power Plant has reduced energy consumption by 45%; The Liuzhou Iron and Steel Plant in Guangxi has also achieved immediate results in energy conservation and consumption reduction by implementing automation, reducing electricity consumption by 63%.

In addition, to ensure the continuous improvement and progress of energy efficiency and energy management, talent cultivation is also crucial. Therefore, energy conservation and consumption reduction should not only be limited to pure industrial production, but also extend to upstream talent cultivation and higher education in China, continuously improving the teaching level of energy efficiency and energy management courses, and making them more in line with China's market demand.

Energy conservation and emission reduction require promoting the adjustment of energy structure. However, as long as the Chinese economy continues to develop, it needs to continuously increase energy. Therefore, for a certain period of time, thermal power as a primary energy source still accounts for a certain proportion.
