The next big thing in lighting technology may be the use of LED lighting in the home.
According to a new report from the UN Climate Institute, by 2050, one billion people will be lighting up their homes with LED light.
The report estimates that by 2027, by far the biggest contributor to the global CO2 footprint will be the power industry, with the majority of this attributable to energy-intensive lighting.
“This is the tipping point where we can have a significant impact on the energy mix of the world and our ability to meet the goals we set for ourselves,” said Alex van der Vliet, executive director of the UN Environment Program.
“By 2030 we will have reached a point where the use and emissions of energy in the world will be equivalent to the amount of CO2 emitted by the entire world economy.”LEDs have become more affordable over the past few years, but they still represent a significant contribution to global emissions.
In the UN’s most recent Global Greenhouse Gas Inventory (GWGI), LED lighting accounts for nearly 40 percent of the total CO2 in the atmosphere, and that figure has risen to more than 50 percent by 2025.”LED lighting is a key contributor to energy efficiency and clean power in the homes of many countries, and we have already seen the benefits from the introduction of this technology in the United States,” said UNEP’s van der Vaart.
“This will only get better, and with the introduction in 2027 of new technologies, we can expect a substantial contribution from the energy sector to CO2 reduction.”
The UN report comes after another report from COVID-19 researchers revealed that there are now more than 6 million LED bulbs in the US.
The bulbs use about 20 percent less energy than the standard fluorescent lightbulbs, according to the report, and the use rate of LEDs is similar to the use rates of LED bulbs.
The COVID outbreak has caused a boom in LED bulbs, which can last for several years and offer many advantages over traditional incandescent bulbs.
In recent years, the number of LED lightbulb installations has doubled, while the price of the bulbs is down dramatically.
According to the UN report, by 2029 the number one contributor to CO 2 emissions will be electricity, with LEDs contributing the largest portion to CO 3 emissions.
That would mean more than half of all CO 2 that enters the atmosphere will be caused by the use in lighting.
The UN said the use could be so large that it would need to shift from electricity to biofuels or bioenergy-based products.
“A switch to LEDs will help us avoid the devastating impact of climate change on our climate, our food security, and our health,” said van der Velde.
“The switch will also help us get a clearer picture of how to improve our energy mix and help us ensure the continuation of economic growth.”
