"Edison invented the light bulb" (in fact, it was improved after buying the patent), which has provided light for human beings since 1880. At that time, the lighting efficiency was better than traditional oil lamps and candles, but nowadays incandescent bulbs are the most energy efficient. One of the poor lighting tools, the same illumination of the incandescent bulb, the power consumption is more than 5 times that of the traditional fluorescent power-saving bulb (CFL), but the life is one-third to one-sixth of the fluorescent power-saving bulb, when it is more provincial The longer-lived LED bulbs have become popular, and incandescent bulbs have become the eye of energy-saving sports.
Under the trend of energy conservation and carbon reduction, many countries and regions have already stipulated the ban on the sale of incandescent light bulbs. Including the Taiwan region, it also announced in 2008 that it will replace the incandescent bulbs in five years. The incandescent bulbs have been banned in various countries. In 10 years, global sales fell from 12 billion to 2 billion, but many developing countries still sell and use incandescent bulbs. Now, the UN has decided not to let incandescent bulbs linger, plans to assist developing countries to introduce lighting. Energy efficiency regulations to completely eliminate the last incandescent bulb.
In the United States, the new lighting energy efficiency regulations will come into effect in 2020, stipulating that the lighting efficiency of the bulb must be above 45 lumens per watt. Under this standard, only the fluorescent energy-saving bulb and the more energy-saving LED bulb can pass, the incandescent bulb will Disabling; Europe, which has long since disabled incandescent bulbs, will further phase out halogen bulbs in September 2018. However, in developing countries, most of them have no relevant regulations, and although LED bulbs and power-saving bulbs are more economical to use for a long time, consumers in developing countries do not have the concept of total cost of use, only because of incandescence. The bulb itself is cheap to buy an incandescent bulb.
In order to solve this energy waste problem, at the end of May 2018, at the Energy Efficiency Global Forum in Copenhagen, the United Nations energy plan "United for Efficiency (U4E), non-profit organization natural resources The Natural Resources Defense Council (NDRC) and Signify have jointly introduced modular guidelines for lighting energy efficiency, which are expected to help the world switch to more efficient lighting.
This guide provides developing countries interested in adopting relevant regulations. As long as "clip-cut" can easily legislate, if you intend to eliminate incandescent bulbs, halogen bulbs and fluorescent power-saving bulbs in one go, directly replace the most energy-saving LED bulbs. , you can choose "A option" (Option A); if you plan to be more gradual, first eliminate incandescent bulbs and halogen bulbs, but temporarily retain fluorescent power-saving bulbs, but countries that encourage LED bulbs, you can choose "B option" (Option B) ). The “Energy Efficiency Unity†program encourages countries to choose the A option as much as possible to create maximum energy efficiency and avoid mercury contamination of fluorescent power-saving bulbs.
At present, the guidelines introduced by the plan are only guidelines for regulating general lighting devices. In the future, they will gradually expand to street lighting, office lighting, industrial lighting and other lighting fields. The Natural Resources Guardian Committee believes that if the current lack of regulations on lighting energy efficiency can adopt this guidance, it will save $18 billion in electricity bills each year and reduce 160 million metric tons of carbon dioxide emissions.
As long as incandescent bulbs are still legally sold in developing countries, global manufacturers will continue to produce and export to developing countries. Many non-profit organizations find that incandescent bulbs are still widely used in the country in dump sites in developing countries. As the population of developing countries grows rapidly, the power supply is gradually becoming more popular. If it is not rushed to regulate, it will increase the use of a large number of incandescent bulbs, causing a surge in electricity consumption. It is necessary to build new power plants, which is a big The burden, while developing countries often choose to burn coal, is a big drain to the global environment. The United Nations hopes to use this program to assist developing countries to reduce energy consumption in the surge.
It’s just that there is no practical benefit in talking about paper. “Uniting for energy efficiency†is not just about writing norms, but also actively recruiting developing countries to promote their application of lighting energy efficiency regulations. At present, there are more than a dozen countries responding, including South Africa, Chile, and Bolivia. Indonesia, Nigeria, Costa Rica, are writing their own legal norms based on the modular norm guidelines. When the United Nations smoothly implements relevant regulations in all countries and implements relevant regulations, the incandescent bulbs that accompany humans for nearly 140 years will gradually The ground is extinct from the earth.
The "Unity for Energy Efficiency" program is not only aimed at incandescent light bulbs. The next target is to make similar specifications for air conditioners, because it is expected that global air-conditioning electricity will be tripled in 2050, and air conditioners are more power-hungry than lighting, so air conditioners are upgraded. Energy efficiency is also an urgent goal.
