Changes
/* Horizontal Axis and Vertical Axis Wind Turbines */
* It can be constructed in off-shores.
* It produces large amount of electricity with high efficiency.
|
* These are easy to build and maintain, safer, easier to transport and they can be mounted close to the ground.
* It operates with any direction of wind
* Production of electricity is less due to low wind speeds near to ground
