Making streetlights LEDs is best way forward, EPA says

By Lee I-chia  /  Staff reporter

The Environmental Protection Administration (EPA) yesterday said if all streetlights nationwide were replaced with LED lights, an estimated 15.4 trillion units of electricity could be saved annually.

Environmental Protection Administration Minister Stephen Shen (沈世宏) made the remarks at the opening ceremony of a two-day forum on achieving a sustainable and low-carbon environment.

He said up to NT$60 billion [US$2 billion] in fuel costs for generating electricity could be saved if all streetlights used LED lights.

In a press released later in the day, the EPA said there were about 2.14 million traditional mercury streetlights and high-pressure sodium lamps in the nation.

Calculating an energy saving rate of 60 percent after switching to high efficiency lighting, about 15.4 trillion units of electricity — approximately the amount of electricity generated by a power plant, could be saved each year, the administration said, adding that it could also save up to NT$3 billion in fuel costs each year, amounting to NT$60 billion over the 20-year life span of the lamps.

However, the EPA said its initial estimated cost for switching over all streetlights to high-efficiency lamps was between NT$50 billion and NT$90 billion and it was negotiating with agencies and private corporations for contributions.

According to the Ministry of Economic Affairs’ Bureau of Energy, the Executive Yuan has approved the use of LED streetlights, and will invest NT$2.8 billion over three years, starting from this year, to replace 3.26 billion mercury streetlamps with lamps of 60 percent electricity saving rate.
