CASE STUDY THE ENVIRONMENTAL IMPACT OF LED BULBS Why are LED bulbs a sustainable choice? In today s world, environmental concerns have become part of our daily lives; for this reason, it is more and more important to make sustainable choices. As far as lightning is concerned, LED lighting has been gaining popularity due to its great environmental benefits. Together with high energy efficiency and longevity, LED bulbs have many characteristics which make them highly sustainable. Reduced toxic elements: unlike older lighting technologies, LEDs contain no dangerous materials like mercury; this means fewer toxic materials released into the environment when bulbs are disposed of. The future of LED bulbs Studies on the spread of LED lighting make it possible to assume that LED lightning will substitute any other type of lightning by 2050, with 90-95 percent of household lighting and 80-90 percent of commercial lighting. As LEDs replace less-efficient lighting, 14-15 gigatons of carbon dioxide equivalent emissions could be avoided in residences and commercial buildings. Moreover, other additional climate and health advantages will derive from replacing other types of lighting with solar LED technology. Adapted from: https://drawdown.org/solutions/led-lighting Lower heat emissions: LED lights emit very little heat compared to incandescent bulbs, which can help reduce the energy required for cooling in homes and commercial spaces. Minimal light pollution: LED lighting can be directed more precisely, preventing unnecessary light pollution, which has harmful effects on both humans and animals; moreover, they are easily dimmable, which helps saving energy. Sustainable manufacturing: LED lights are manufactured with a focus on sustainability, often using recyclable materials and eco-friendly production processes. For the reasons above, people and businesses can make a significant contribution to environmental conservation by choosing LED lighting. dimmable: oscurabile 17 Answer the questions. 1.
