Sample questions
01In wind energy, what does the term 'capacity factor' represent?
- AActual energy output versus the theoretical maximum
- BThe peak power the turbine can produce in a gust
- CThe wind speed at which the turbine shuts down
- DThe ratio of blade length to tower height
Why: Capacity factor is the ratio of actual energy output to the theoretical maximum if the turbine ran at rated power continuously.
02Which factor most significantly affects wind turbine power output?
- AHumidity
- BTemperature
- CWind speed
- DAir density
Why: Wind speed has the most significant impact on power output, with power proportional to the cube of wind speed.
03Which wind turbine design is most common for utility-scale installations?
- AVertical axis with a Savonius rotor
- BHorizontal axis with a three-blade upwind rotor
- CDucted shrouded turbine
- DHorizontal axis with a downwind rotor
Why: Three-blade horizontal-axis turbines with an upwind rotor are the dominant design for utility-scale wind installations.
