Renewable Energy Quiz

What type of renewable energy is depicted in the image?

• Solar energy

• Hydroelectric energy

• Wind energy

• Geothermal energy

Which additional renewable energy source is shown in the image along with wind turbines?

• Biomass

• Solar panels

• Nuclear energy

• Wave energy

What is the function of the "yaw drive" in a wind turbine as shown in the diagram?

• It controls the angle of the blades.

• It generates electrical power.

• It measures wind speed.

• It rotates the nacelle to face the wind.

According to the diagram, which part of the wind turbine is responsible for converting mechanical energy into electrical energy?

• Rotor

• Gear box

• Generator

• Anemometer

What is the purpose of the "anemometer" on a wind turbine as indicated in the diagram?

• It controls the turbine's operations.

• It measures wind speed.

• It generates power.

• It adjusts the blade angle.

How tall are wind turbines typically, as mentioned in the image?

• Over 200 feet tall

• Over 300 feet tall

• Over 400 feet tall

• Over 500 feet tall

What is the primary function of the tower in a wind turbine system as described in the image?

• To generate electricity

• To support the nacelle and all parts associated with it

• To convert wind energy directly into mechanical energy

• To store the electricity generated by the turbine

What additional role does the tower play in the functionality of a wind turbine system?

• Acts as a lightning rod

• Provides a base for cables that carry the electricity to the ground and out to the power grid

• Regulates the speed of the wind

• Measures the wind speed and direction

What is the function of the nacelle in a wind turbine?

• It stores the electrical energy produced.

• It contains all the equipment associated with making electricity.

• It supports the structure of the wind turbine.

• It captures wind energy directly.

What does the gear box in a wind turbine do?

• It reduces the speed of rotation from 1800 RPM to 18 RPM.

• It converts wind energy into mechanical energy.

• It increases the speed of rotation from 18 RPM to 1800 RPM which is required for the generator.

• It stops the turbine when the wind speed is too high.
