Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the betz's limit?Theoretical maximum efficiency for wind turbines, approximately 59.3% of wind's kinetic energy
2. What is the operational emissions?Zero greenhouse gas emissions and air pollutants during electricity generation
3. How do wind turbines make electricity?Wind pushes the blades, which spin a rotor. The rotor turns a shaft, goes through a gearbox, and a generator turns that motion into electricity.
4. Why is wind power good for the planet?It doesn't produce harmful gases while it works, so it helps clean the air and fights climate change by replacing dirty power from fossil fuels.

Horizontal-Axis Wind Turbine (HAWT): A wind turbine where the main rotor shaft and generator are positioned at the top of a tower.
Decarbonization: The process of reducing or eliminating carbon dioxide emissions from human activities.
Intermittency: The characteristic of some renewable energy sources, like wind and solar, to not be available constantly.
