1. Introduction Green lighting is a descriptive term for lighting systems that are highly efficient, energy-saving, and environmentally friendly. New light sources such as high-efficiency fluorescent lamps, high-pressure sodium lamps, low-pressure sodium lamps, metal sulfide lamps, and compact fluorescent lamps all possess high efficiency, energy saving, comfort, and reduced environmental pollution, hence the name "green lighting" (i.e., energy-saving lamps). 2. Prominent Problems in China's Lighting Electricity Consumption 1) The growth rate of electricity consumption lags behind the development demand for lighting electricity. In recent years, China's lighting electricity consumption has grown rapidly. In 1995, China's lighting electricity consumption was 100 billion kWh, and by 2000, it was expected to reach 140 billion kWh, almost consuming the annual power generation of two Three Gorges Dams. Furthermore, according to estimates from 1984 to 1989, China's average annual growth rate of electricity generation was 95%, while the average annual growth rate of lighting electricity consumption was only 14.5%. 2) Lighting technology is relatively backward, with most still using incandescent lamps with low luminous efficacy. In recent years, incandescent lamps have accounted for over 85% of all lighting sources in China, and rural electricity consumption reaches as high as 98%. If 10% of these were replaced with energy-saving light sources, billions of kWh of electricity could be saved annually. 3) Low level of lighting maintenance and management. Especially in public places and roads, lighting is not switched on and off on time, and regular cleaning and maintenance are even less frequent. 4) Unreasonable lighting design. Mainly, the lighting power is high but the luminous efficiency is poor, especially the application effect of control devices, resulting in serious waste of electricity. 5) Poor awareness of energy conservation throughout society, leading to significant waste. 3. Benefit Analysis of Implementing Green Lighting Projects Indeed, implementing green lighting projects in China can improve lighting quality on the one hand, and save about 20% of lighting electricity on the other, i.e., 30 billion kWh, equivalent to saving more than 15 million tons of raw coal. At the same time, it will effectively reduce the emission of pollutants such as dust and ash. Clearly, its economic, social, and environmental benefits are considerable. A detailed analysis follows. 3.1 Energy Saving: From nothing to something, electric light source products have developed from a single incandescent light source to over 40,000 types today. Every stage and every variety of development is closely related to energy saving in lighting. Energy saving has gradually become a crucial indicator of the survival and development of electric light source products. Tests have shown that only 10% of the electrical energy of an incandescent lamp is converted into visible light, while 90% is wasted as invisible infrared radiation. In air-conditioned rooms, the heat generated by incandescent lamps increases the load on the air conditioner, resulting in even more energy waste. The energy-saving effect of using energy-saving lamps is shown in Table 1. 3.2 Cost Saving: Due to the excellent energy-saving effect of energy-saving lamps, the electricity savings can offset the extra cost of purchasing lamps within just a few months, as shown in Table 2. 3.3 Environmental Protection: The so-called green lighting project aims to save electricity for lighting while ensuring lighting quality, reducing emissions of waste gas and particulate matter generated by power generation, thereby protecting the global environment. As is well known, during coal-fired power generation, coal combustion in boilers produces CO2, SO2, NO, and dust ash, polluting the atmosphere and affecting human health. Promoting the use of energy-saving lamps obviously saves coal while also purifying the environment. 3.4 Peak Suppression In recent years, the country has accelerated power construction and urban and rural power grid transformation. Although power supply in most areas has eased somewhat, reducing peak demand and adjusting load still has technical and economic significance. Moreover, in some areas, power outages and rationing still occur frequently during peak seasons. If energy-saving lamps are widely promoted, peak electricity consumption for lighting can be reduced, decreasing the pressure on peak electricity demand and the installed capacity of power generation equipment. 4. Policy Recommendations for Implementing Green Lighting Projects 4.1 Extensive Publicity and Changing Mindsets It is recommended to vigorously publicize the practical and long-term significance of green lighting projects through various media such as radio, television, and newspapers. Through extensive publicity, people can adapt to the demands of the times and change their consumption concept of low investment and high energy consumption. 4.2 Improve methods and manage scientifically. Design the best lighting scheme according to the different requirements of different occasions and levels; reduce the lighting time while meeting the needs. At the same time, in terms of lighting management, it is also necessary to introduce TPO management [Time, Place, Occupation]. Its key factors can be summarized into three points: First, eliminate waste of electricity; second, adopt efficient lighting measures; and third, strengthen the inspection and maintenance of lighting equipment. 4.3 Improve standards and strengthen supervision. It is recommended that all energy management departments effectively implement their supervisory and management authority and use lighting sources with high luminous efficiency as much as possible within their jurisdiction. For example, fluorescent lamps or energy-saving fluorescent lamps should be used instead of incandescent lamps for indoor lighting; high-pressure sodium lamps and metal sulfide lamps should be used instead of high-pressure mercury lamps and tubular tungsten lamps for factory workshops and large-area outdoor lighting; high-pressure sodium lamps and low-pressure sodium lamps should be used instead of high-pressure mercury lamps for road and square lighting. Incandescent lamps of 100W or more should not be used for residential lighting, and should be replaced with energy-saving fluorescent lamps or high-efficiency fluorescent lamps.
