Renewable Energy: Wind Power Essay

747 words - 3 pages

Wind is one type of renewable energy that can be developed to generate free and clean energy replacing the one that be renewed and cause the pollution such as fossil fuel. Wind energy can be extracted by using the suitable wind turbine that is suitable with the current wind speed at observe location which is eastern coast of peninsula Malaysia. Generally, Malaysia has a potential to use the wind as alternative energy because of the wind speed in Malaysia can reached until 12 m/s and this is the advantages for Malaysia to using wind power to generate power for using such as generating electricity.

Figure 2: iWIND Vertical Axis Wind Turbine (VAWT)

The main advantages of using this, VAWT can catch winds from all directions which is (360 degrees). So, it can start-up at lower wind speed about 0.8 m/s and cut-in (generate power) at wind speed 2.5 m/s. They are very low in noise, occupies less space and light in weight. VAWT are also safer for wildlife such as birds and bats. They suitable to be installed in metropolitan area including in high rise place. Other that, iWind VAWT have the following features:
a. Turbine rotor blades are made from FRP composites which are light weight. The rotor surface smoothness is 0.9 micron.
b. The rotor blades are anti-UV, acid and alkaline resistant and heat and cold resistant. They are suitable for installation in most area and climates.

The rotational axis is perpendicular to the wind direction. The generator is on ground level so they are more accessible and they don’t need a yaw system. Because of it on the ground, wind speeds available are...
