7.26. The conversion of the kinetic energy of wind to electricity may be an attractive altemative to the use of fossil fuels. Typically, wind causes the rotor of a turbine to turn, and a generator converts the rotational kinetic energy ofthe rotor into electricity. Power generated by a wind turbine (Ws) can be estimated from the density of the air (p), wind speed (u), and turbine rotor diameter (D) using the following formula лD? 1 W. ти* х п, where...
