WIND ENERGY - GROUP 2

What factors determine the efficiency of a wind turbine?

• Wind speed and turbine size

• Turbine color and blade shape

• Distance from the equator and elevation

• Number of blades and material composition

What device is used to capture wind energy?

• Solar panels

• Wind turbines

• Hydroelectric dams

• Geothermal plants

Which of the following is a benefit of offshore wind farms compared to onshore ones?

• Lower construction costs

• Less impact on marine ecosystems

• Closer proximity to urban areas

• Wind direction only

• Wind intensity

How is mechanical energy converted into electrical energy in a wind turbine?

• Through wind shear

• Through direct transmission

• Through electromagnetic induction

• Through wind direction

Which of the following statements best describes a major challenge of installing wind farms in remote locations?

• Difficulty in transporting electricity from wind farms to urban areas

• Higher construction costs due to difficult terrain

• Limited access to skilled labor

• Stricter environmental regulations in remote locations
