Why LED lighting hasn’t yet reduced energy consumption

Owner of the Altitude bike shop in Waterford, Ireland, Eamon Barrett, advises lighting up a bicycle if you want to sell it. The chrome, the glossy new spokes, and the glossy technicolor paints all gleam in the brilliant light. However, Mr. Barrett started to get uncomfortable with fluorescent lights burning nonstop to support the move to a supposedly green mode of transportation. Approximately three years prior, he made the decision to convert Altitude’s showroom, workshop, cafeteria, and back offices to LED lighting that is more energy-efficient.

Certain places now only have lights on when someone enters the room thanks to motion sensors. A battery and some new solar panels power the system in part. “Everyone benefits,” Mr. Barrett claims. “The quality of the lighting is better.” Moreover, he claims that his yearly electricity bill has decreased by 35%. Mr. Barrett continues, “If not for Russia’s invasion of Ukraine, which sharply increased energy prices, those savings would be even greater.”

Despite being around for decades, not many businesses have installed LED lights. That has anything to do with the initial switchover cost. Mr. Barrett estimates that he replaced the lights on his 6-7,000 square foot property for about €10,000 (£8,800; $10,900). In addition to the increased expense of the solar panels and battery, he predicts that it will take about seven years to recover this. LEDs achieved a major milestone last year. The International Energy Agency stated that they accounted for 50% of lighting sales worldwide. On the other hand, the amount of energy used for lighting is actually increasing as more and more individuals install electrically powered lighting worldwide.
