Harnessing The Wind: A Sustainable Future Energy For Malaysia By Prof. Ts. Dr Mohd Zamri Ibrahim Dr Aliashim Albani Yong Kim Hwang Eastern Corridor Renewable Energy (ECRE) School of Ocean Engineering, Universiti Malaysia Terengganu T he terms wind energy or wind power describe the process by which the wind, as kinetic energy, is exploited as a resource to generate mechanical power (Figure 1) and electrical power (Figure 2). Wind turbines operate on a simple principle - the wind turns the blades, which spin a shaft connected to a generator which generates electricity. Modern wind turbines can be divided into two basic groups (Figures 3, 4 and 5), the horizontal- axis wind turbine (HAWT) and the vertical-axis wind turbines (VAWT, Darrieus and Savonius Figure 1: Mechanical components of wind turbine (Source: Behera and Sarkar, 2012) Figure 2: Electrical components of wind turbine (Source: Behera and Sarkar, 2012) 33
