This is from Chapter 10 of Sustainable Energy second edition by Richard Dunlap Two locations have the same average wind velocity. Location A has a constant wind velocity of 10 m/s, while Location B has a wind velocity of 5 m/s for 12 hours per day and a wind velocity of 15 m/s for 12 hours per day. Compare the total energy produced per day for identical wind turbines at the two locations. The energy is given by the formula E = 0.5*(air density)*(efficiency)*velocity^3*(Turbine area)*time. Keep the answer in terms of (efficiency)*(Area). **Also is v average velocity or regular, non-average velocity?***
