United Nations: help developing countries wipe out incandescent lamps thoroughly and change LED lights comprehensively.

The traditional incandescent bulb invented by Edison, which has actually been a patent, has been providing light for mankind since 1880. The efficiency of lighting was superior to that of traditional oil lamps and candles. But incandescent bulbs are one of the most energy efficient lighting tools in the world. The traditional fluorescent power saving lamp (CFL) is more than 5 times, but life expectancy is 1/3 to 1/6 of the fluorescent power saving lamp. When the LED bulb with longer power consumption and longer life begins to become popular, incandescent bulbs become the thorn in the energy saving campaign.

Under the trend of energy saving and carbon reduction, many countries have already banned the sale of incandescent bulbs, including the Taiwan area, which announced in 2008 that it could completely replace incandescent bulbs in 5 years. Under the prohibition of incandescent bulbs in various countries, global sales dropped from 12 billion to 2 billion in the past 10 years, but there are still many developing countries. Today, the United Nations has decided not to allow incandescent bulbs to linger, and plans to help developing countries introduce energy efficiency codes to eliminate the final incandescent bulbs.

In the United States, the new lighting energy efficiency regulations will come into effect on 2020, requiring that the lighting efficiency of bulbs must be above 45 lumens per watt. Under this standard, only fluorescent fluorescent bulbs and more energy-efficient LED bulbs can be cleared. Incandescent bulbs will be banned. Europe, which has long banned incandescent bulbs, is further in September 2018. We need to eliminate halogen bulbs. However, most of the developing countries do not have the relevant specifications. Although the LED bulbs and power saving bulbs are more economical to use for a long time, the consumers of developing countries do not have the concept of total cost of use. They only buy incandescent bulbs because of their cheap incandescent bulbs.

To solve this problem of energy waste, at the end of May 2018, on the Energy Efficiency Global Forum in Copenhagen, the United Nations Energy Program "United for Efficiency" (U4E) and the NGO Natural Resources Protection Committee (Natural Resources Defense) NDRC and Signify jointly launched the modular guidelines for lighting energy efficiency, which is expected to help the global switch to efficient lighting.

The guidelines provide the developing countries with the intention to adopt relevant specifications. As long as "clip and paste" can be easily legislated, if we intend to eliminate incandescent bulbs, halogen bulbs and fluorescent power saving bulbs at one time, we can directly replace the most energy-efficient LED bulbs in the country. We can choose "A A" (Option A); First, eliminate incandescent bulbs and halogen bulbs, but temporarily retain fluorescent power saving bulbs, but only encourage LED bulbs to choose the "B option" (Option B). The "energy efficiency solidarity" plan encourages countries to choose A options to maximize energy efficiency and avoid mercury pollution from fluorescent light bulbs.

At present, the guidelines issued by the plan are only for guiding general lighting installations, and will gradually expand to street lighting, office lighting, industrial lighting and other lighting areas in the future. The Natural Resources Defense Council believes that if the current lack of lighting energy efficiency related norms, this guideline can be adopted, which will save us $18 billion in annual electricity expenditure and reduce 160 million metric tons of carbon dioxide emissions.

As long as incandescent light bulbs are still legally sold in developing countries, global manufacturers will continue to produce and export to developing countries. Many non-profit organizations are developing waste dumps in China. They have discovered that incandescent bulbs are still widely used in the country, and because of the rapid growth of family members in developing countries, the power supply is also gradually developing. Popularization, if not standardized, will increase the amount of incandescent light bulbs, resulting in a sharp increase in electricity consumption. The construction of new power plants is a great burden on developing countries. Developing countries often choose coal-fired power generation, which is a big news for the global environment. The United Nations hopes to use this plan to help developing countries reduce energy consumption in the boom.

There are no practical benefits. "Energy efficiency and solidarity" is not just about writing norms, but also actively recruiting and developing countries to promote their application of lighting energy efficiency standards. At present, more than a dozen countries have responded, including South Africa, Chile, Bolivia, Indonesia, Nye and Leah, Costa Rica. Based on this modular guideline and writing national laws and regulations, when the United Nations successfully implements all relevant norms and implements relevant norms, the incandescent bulbs that accompany humanity for nearly 140 years will gradually disappear from the earth.

The "energy efficiency solidarity" plan is not only aimed at incandescent bulbs, but the next goal is to make similar specifications for air conditioners. It is expected that the global air conditioning power consumption will increase by 3 times in 2050, and air conditioning will consume more electricity than lighting. Therefore, improving the energy efficiency of air conditioning is also an imminent goal.
