Essay on Wind Turbine: Top 7 Essays
Wind turbines can rotate about either a horizontal or a vertical axis, the former being both older and more common. B. Vertical-Axis Wind Turbine: Vertical-axis wind turbines (or VAWTs) have the main rotor shaft arranged vertically. Key advantages of this arrangement are that the turbine does not need to be pointed into the wind to be effective.
