According to Taiwan Ministry of Economic Affairs, the island has completed the replacement of all 696,700 incandescent traffic lights with LED signals this year , which comes after Singapore to become the second city to hifted entirely to LEDs.

Compared to traditional incandescent traffic signals, LED traffic lights consume 85 percent less energy, meaning that the new lights will help the island save 247 million kilowatt-hours of electricity a year. Additionally, the LED lighting project will further expand to include the replacement of mercury-vapor streetlights next year.

Since the energy conservation campaign was launched, the government has issued over 166 million "energy labels" to products with energy conservation features. With the program, the city saves energy equivalent to 122,000 kiloliters of oil a year and reduce carbon emissions by 310,000 metric tons a year.

Currently, 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.
