What is a major advantage of wind turbines compared to traditional power plants?

• They can operate without wind.

• They require less maintenance.

• They produce no pollution or greenhouse gases.

• They are cheaper to build.

Why are taller wind turbines more effective?

• They are easier to maintain.

• They are less likely to be damaged by storms.

• They can capture more wind due to higher wind speeds at greater heights.

• They are cheaper to construct.

What is the main challenge of transporting large wind turbines?

• They require special permits for transportation.

• They are too heavy for most vehicles.

• They are too large to transport easily onshore.

• They are difficult to maneuver through narrow roads.

How do wind turbines generate electricity?

• By rotating blades that move a magnet inside wire coils, creating an electrical current.

• By using water to turn a generator.

• By using chemical reactions to produce energy.

• By converting solar energy into electrical energy.

Why is specific wind prediction important for power companies?

• To reduce the cost of wind energy production.

• To optimize the integration of wind energy with other power sources.
