1. Macroeconomic pressures

Energy is an important material basis for national economic and social development. China's lack of resources and energy shortage have become an important factor restricting the sustainable development of the national economy. Due to the extensive economy at this stage, energy utilization efficiency is low and energy consumption is high, resulting in serious waste of energy. The phenomenon is very serious, and the shortage of energy has caused huge pressure on my country's lack of resources and environmental governance.

p The world's available energy has dropped sharply, threatening the survival of human beings

p International energy shortage threatens national security

p Energy conservation and improvement of utilization efficiency are related to the sustainable development of the country

p Energy has a growing impact on economic development

p my country's per capita fresh water, oil, natural gas and coal occupancy is far lower than the world average, and energy and water resources consumption is higher than the world level. China's energy consumption in 2007 was higher than the world average, accounting for 50% of the growth in global energy consumption. Energy consumption and water consumption per 10,000 yuan of GDP are higher than those of developed countries.

p Energy saving and emission reduction: The 1992 United Nations Framework Convention on Climate Change/1997 Kyoto Protocol has become a common measure to reduce emissions and protect the earth.

Consumption of coal and fossil fuels not only pollutes the environment, but also induces problems such as the greenhouse effect, acid rain, disease, and agricultural production reduction. Reducing energy consumption and improving energy efficiency can reduce emissions, reduce harm, and promote sustainable development.

2009 Copenhagen World Climate Conference - China pledged to reduce carbon emissions by 40%--45% per unit of carbon emissions in 2020 compared to 2005, and it is imperative to save energy and reduce emissions.

2. Experience from Micro-Energy Management Practices

There are three main ways of industrial energy saving: structural energy saving, technical energy saving and management energy saving. In energy management, it is gradually recognized that the development and application of energy-saving technologies and equipment is only one aspect of energy-saving work, and simply relying on energy-saving technologies cannot ultimately solve problems such as the contradiction between energy supply and demand. The key to energy management is to apply systematic management methods to reduce energy consumption, improve energy utilization efficiency, promote behavioral energy conservation, and build an energy management system. The characteristics and effects of energy conservation management include:

p High input-output ratio of management energy saving

p Management energy saving is the support of technical energy saving and structural energy saving

p Low investment in energy conservation management, suitable for developing countries

p Management energy saving can be widely applied at the enterprise level

p The application effect is good. For example, Ireland saves energy consumption by 7% through the energy management system (MSE). In China, due to the relatively poor level of energy management at this stage, the proportion of energy saving through management is estimated to be as high as 10%.
