Switch On To Green Lifestyle

SCMP – Updated on Jan 10, 2009

A number of your correspondents have written to these columns about energy saving light bulbs.

These light bulbs are collected for recycling in Hong Kong. Improper disposal may lead to pollution. However, proper use and disposal leads to massive environmental advantages – saving energy, saving the Earth’s limited resources and reducing greenhouse gas emissions.

Also, ordinary light bulbs generate more heat and in the hot weather this leads to increased energy consumption by air conditioners. I was in Britain in October and one large supermarket chain was selling a limited supply of energy saving bulbs for the equivalent of HK$1 instead of the usual HK$25.

In Hong Kong there is no excuse for people not to try to work harder to reduce energy use and live a greener life.
