Taiwan has completed the replacement of all 696,700 incandescent traffic lights around the country with light-emitting diode (LED) signals this year, the Ministry of Economic Affairs said yesterday.
It makes Taiwan the second country after Singapore to have shifted entirely to LED traffic lights, according to officials at the Bureau of Energy.
The officials said LED lights consume 85 percent less energy than incandescent traffic signals, meaning the new lights should help the country save 247 million kilowatt hours of electricity a year.
The LED lighting project is set to be expanded next year to include the replacement of mercury-vapor streetlights, the officials said.
Since the energy conservation campaign was launched, the government has issued more than 166 million “energy labels” to products with conservation features, the officials said, adding that the program has helped the country save the equivalent of 122,000 kiloliters of oil a year and it has reduced carbon emissions by 310,000 tonnes a year.
In the first three quarters of this year, energy intensity dropped 6.92 percent from the same period last year, the biggest improvement in any year with economic growth over the past two decades, they said.
So far, 20 business groups have signed a voluntary energy conservation agreement, with the goal of decreasing energy consumption by 5 percent, or 14 million kilowatt-hours, over a three-year period until 2013, the officials said.
