The Hong Kong administration proposes to phase out energy-inefficient incandescent light bulbs to conserve energy and reduce carbon emission.
The administration has launched a three-month public consultation on whether to restrict the sale of such light bulbs, taking into account replacement options for these bulbs, Xinhua reported.
Electrical and Mechanical Services Deputy Director Chan Fan said 90 percent of the electricity used to light an incandescent light bulb by heating its tungsten filament is lost as heat, and only 10 percent is used for lighting.
“Replacing incandescent light bulbs with more energy-efficient products will achieve substantial saving in electricity consumption,” he said.
People can save money on electricity bills and reduce greenhouse gas emission, he added.
The scheme is expected to save around 390 million Hong Kong dollars ($50 million) from electricity bills annually and reduce carbon emission by 273,000 tonnes.
