U.S. cities implement LED street lamp renovation plans, greatly reducing energy consumption costs
Because LED bulbs have the advantages of reduced energy consumption, relatively low maintenance frequency, and longer life span, many cities in the United States have successively promoted plans in recent years to convert traditional bulbs such as high-pressure sodium lamps and mercury lamps into LED bulbs. Shakopee, a city in Minnesota, also plans to switch to LED street lights by the end of 2018.
The city of Shakopee in Minnesota, USA, also plans to convert all 1,500 street lights in the city to LEDs by the end of 2018. The engineer in charge of this plan, ChrisTIan Fenstermacher, estimates that the replacement cost is $600,000. However, the annual energy consumption and maintenance costs will be saved after the completion of 100,000 US dollars, and the replacement LED street lights are expected to last 20 years.
In addition to cities in the United States, St. Catharines, Ontario, Canada, from November 2015 to May 2018, the local government promoted relevant plans to switch 93% of the city’s street lights to LED lights. It costs 7.15 million US dollars, but it has begun to show results in terms of energy saving.
According to local government statistics, the cost of energy consumption dropped from US$2 million in 2015 to 1.19 million in 2017. As for maintenance, the annual saving was US$398,000 in 2017, which was more than the original estimate of 350,000. The mayor of St. Catharines, Walter Sendzik, said that this plan will not only save the government costs, but residents will also benefit from lighting improvements in the future.
