More than 1,000 students were invited to Lamma Island as part of an eco-tour organised by Hongkong Electric last month. The visit aimed to raise students' awareness of energy conservation and environmental protection. The students, who joined the HK Electric open day, visited the old coal and gas burning power station and the new wind-powered generator at Tai Ling. The new plant is called Lamma Winds. It was commissioned in 2006 and is the first of its kind in Hong Kong. After visiting the turbine, volunteers led the students on an eco-tour that introduced them to the island's rich ecological resources. 'Home use is a major source of energy consumption. Where possible, choose electrical appliances with energy-saving labels and avoid keeping them in stand-by mode when not in use,' said Francis Cheng Cho-ying, HK Electric's general manager. He hoped the open day would encourage the students to think and act green.
