LED street lamps reduce energy consumption and push and redress the big cities of the United States and Canada

Shakopee, the city of Minnesota, also plans to switch all 1500 street lights in the city to LED by the end of 2018, and Christian Fenstermacher, an engineer in charge of the project, estimates the replacement cost of $600 thousand. But the annual energy consumption and maintenance cost will be saved by 100 thousand dollars after completion, and the replacement LED street lamp will be expected to be used for 20 years.

In addition to American cities, in St. Catherine, Ontario, Canada, from November 2015 to May 2018, the local government pushed 93% of the city's street lights to LED lights, which cost $7 million 150 thousand, but it has begun to be effective in energy conservation.

According to local government statistics, the cost of energy consumption dropped from $2 million in 2015 to 1 million 190 thousand in 2017, and the maintenance aspect was $398 thousand in 2017, more than the previously estimated 350 thousand. Walter Sendzik, the mayor of St. Catherine, said the plan would not only save the government, but the residents would benefit from lighting improvement in the future.
