About 15% of the world's electricity consumption is used for lighting, and inefficient lamps not only increase electricity bills, but also increase carbon emissions. With the increase in environmental awareness, energy-saving lamps have changed from "optional" to "must-have". Choosing an environmentally friendly lamp is not only to save money, but also for the future of the earth.
The Elimination of Incandescent Lamps: The End of An Era
The incandescent lamp was invented in the 19th century, but its energy efficiency is extremely low - 95% of the electricity is converted into heat, and only 5% is used for light. Since 2009, the European Union, the United States, China and other countries have successively banned the sale of incandescent lamps and turned to more efficient CFL (energy-saving lamps) and LEDs. This policy has reduced global lighting energy consumption by about 30%.
LED Revolution: A Combination of Energy Saving and Long Life
The energy consumption of LED lamps is only 1/10 of that of incandescent lamps, but the life span is more than 25,000 hours (equivalent to 20 years). If all households around the world switch to LED, carbon emissions can be reduced by about 180 million tons per year, which is equivalent to shutting down 160 coal-fired power plants. In addition, LEDs do not contain mercury and are more environmentally friendly than CFLs.
Solar Lamps: The Future of Off-grid Lighting
In areas with unstable electricity such as Africa and South Asia, solar lamps are changing the lives of millions of people. For example, the "M-KOPA" solar system in Kenya allows families to obtain lighting on an installment basis, replacing expensive kerosene lamps. This type of technology is not only environmentally friendly, but also promotes social equality.
Recycling And Sustainable Design
The environmental protection of lamps is not only in the use stage, but also in the treatment after disposal. Brands such as IKEA have launched the "Old Lamp Recycling Program" to encourage consumers to return discarded lamps to recycle metal and glass. In addition, designers have begun to try degradable materials such as bamboo, mycelium, and even recycled plastic bottles to make lampshades.
Everyone Can Become A Promoter of "Green Lighting"
Choosing energy-saving bulbs, supporting recycling programs, and making rational use of natural light... Small actions together can make the earth more sustainable. The next time you change a lamp, you might as well ask yourself: Can this lamp also reduce the burden on the environment?
