A CAMPAIGN to educate youngsters about squandering electricity was woefully inadequate to deal with Hong Kong's huge energy wastage, legislators and environmentalists said. Head of the Legislative Council's environmental affairs panel Peter Wong Hong-yuen said it was two years since campaign initiator China Light and Power (CLP) had paid $500,000 for a conference with Friends of the Earth on energy efficiency. ''I would like to challenge them to tell me how they've moved [since then],'' he said. Mr Wong said the power company ought to be targeting commercial buildings, which used 40 per cent of the territory's power with an enormous wastage of electricity. His comments follow CLP's launch of a drive to visit all 340 secondary schools in Kowloon and the New Territories. The company will give away rucksacks and plastic watches during its presentations of energy-saving tips, such as turning off lights when leaving the room. Jimmy Lui Wing-yiu, CLP general manager for distribution and customer services, denied suggestions that better energy saving could reduce the need to build more power stations. Simon Chau of lobby group Green Power dismissed the move as a publicity stunt which duplicated an effort by the Environmental Campaign Committee.
