The difference in kilowatt hours of monthly energy production between an average local wind speed of 15 miles per hour and an average local wind speed of 10 miles per hour would be of a third less kilowatts produced with a 10 miles per hour wind than with a 15 miles per hour wind.
Step-by-step explanation:
This is because 10 corresponds to 2/3 of 15, 1/3 being the remaining value of electrical production that would not be generated with a wind of 10 mph rather than a 15 mph wind.
