Energy-saving standards will be upgraded again, and high-efficiency motors may become explosive models!

Energy-saving standards will be upgraded again, and high-efficiency motors may become explosive models!

In order to continuously promote the updating, upgrading and application of energy-saving standards, support energy-saving and carbon-reducing reforms in key areas and industries, accelerate the research and development, promotion and application of advanced energy-saving and carbon-reducing technologies, and resolutely curb the blind development of high-energy consumption, high-emission, and low-level projects, the national development and reform The Committee worked with relevant departments to study and formulate the "Notice of the National Development and Reform Commission and the General Administration of Market Supervision on Further Strengthening the Updating and Application of Energy Conservation Standards (Draft for Comment)" and solicit opinions from the public. Looking at the full text of the opinion draft, the overall promotion effect on high-efficiency motors is very obvious. High-efficiency motors in the true sense will become the mainstream of the market, and a new motor market structure will surely be formed.
