Different Types and Parts of a Horizontal Axis Wind Turbines

Onshore and Offshore Wind Turbines

Onshore wind turbines	Offshore wind turbines
Advantages It requires cheaper foundations Easily intergrated with the electrical- grid network cheaper Installation and access during the construction phase. It can be operated and maintained easily and cheaply Source:Onshore Vs Offshore Wind Turbines	These are two types, namely Near shore and Off shore. Advantages: The roughness of the water surface is very low Wind and obstacles to the wind are less. so, large turbines can be installed Noise pollution is also not a factor because these are too far from shores Less affected to turbulance in wind and low wind shear
Disadvantages Neagtive visual impact or noise. Limted avaliability of lands Restrictions asscociated with obstructions like buildings, mountains, etc. Noise pollution Afftected to more turbulance Sources:Wind Power,Types of Wind Farms	Disadvantages: Installing offshore windturbines is much more complex and costly Connection to the utility grid is also much more complex and expensive Operation and maintanances is also a complex task with off shore wind turbines Source:Offshore Technology
