According to the United Nations (UN) study, CFC compact lamps or LED lamps have an energy saving advantage of 20% to 50% and have a lifetime of 10 times higher than incandescent bulbs. same capacity.
Therefore, if all countries in the world replace incandescent light bulbs with energy-saving compact bulbs, the world's lighting demand will be reduced by 2% / year compared to the current. This is equivalent to reducing 800 million tons of CO 2 emissions.
The Telegraph reported that the study was presented at the UN Climate Change Summit, which took place in Cancun (Mexico) to call for countries to further promote the use of secret light bulbs. Energy saving to cope with global warming.
The report also provides specific examples of the benefits of replacing incandescent bulbs with energy-saving light bulbs. For example, Indonesia could save $ 1 billion a year and could cut 8 million tons of carbon dioxide released into the atmosphere each year if it completely replaced the incandescent light.
Meanwhile, small and underdeveloped countries like Cambodia can also save 30% of their electricity demand and reduce CO2 emissions into the air every year if they use a full lighting system. energy saving lamp.
The UN says that countries can choose the best ways depending on their own conditions to encourage people to use energy-saving light bulbs. These measures may include: banning the use of incandescent bulbs, taxing incandescent light companies and subsidizing prices for compact lamps.
Currently, the countries of the European Union, the US, Australia, Cuba, Canada and the Philippines have completely banned the use of incandescent bulbs. The UN is also working with representatives from China, Russia, Vietnam and Morocco to convince these countries to adopt similar bans.
