Wind Power Quiz Worksheet

Explore how wind turbines generate power, then use the information and data below to solve the questions. Write your answers in the spaces provided.

Wind into electricity

Wind is moving air. It can turn turbine blades, which spin a shaft connected to a generator. The generator converts some of the turbine’s movement energy into energy that can power homes and businesses. Wind is renewable because it is naturally replenished; using wind to generate power does not use it up.

1.Which sequence best describes how a wind turbine generates electricity?

Wind turns the blades → the shaft spins → the generator produces electricity
The generator heats the air → the air turns the blades → electricity is stored
The blades make wind → the wind spins the Sun → electricity flows
Wind enters the tower → the tower burns fuel → electricity is produced

2.Complete the sentence: A wind turbine’s generator changes movement energy into energy.

3.Wind is a renewable energy source. Explain what renewable means in this context.

A windy-day test

A student compares the average wind speed at a small test turbine with its power output. The figures are simplified data for this activity.

Average wind speed (m/s)

Power output (kW)

4.Use the test turbine results. What power output was recorded when the average wind speed was 8 m/s?

5.Use the test turbine results. Between which two recorded wind speeds did the power output increase the most?

6.True or false: The test results show that power output increased as wind speed increased.

Benefits, limits and choices

Wind turbines generate electricity without burning fuel while they are operating. However, wind speed changes, and turbines do not generate the same amount of electricity all the time.

7.Anahera is planning electricity for a small coastal community. Which is a useful advantage of including wind power in the electricity supply?

It can generate electricity without burning coal or gas while operating
It guarantees the same electricity output in every kind of weather
It can store unlimited electricity inside the turbine blades
It removes the need for every other electricity source

8.Anahera’s community cannot rely on strong wind every hour. Give one reason it would be sensible to combine wind power with another source of electricity or with energy storage.

9.A community is considering a wind farm. Describe one benefit and one challenge the community should weigh up before deciding.
