A wind engineer measured the amount of kinetic energy a prototype turbine produced when placed in locations with different average wind speeds around the United States. A graph of the results is found above. What
inference can be made about operating this type of turbine at a location with an average wind speed of > 20
kph?

Monthly Energy Output/kWh
A The stronger the wind blows, the greater amount of energy that can be produced
B. The average speed of the wind is not as important to energy production as daily speed of the wind
C in strong winds the air pressure is too great for the blades of the turbine to turn
D. There is no energy produced when the winds are blowing strongly
