What are the limitations of extracting energy from:

(a) the wind?

Dear Student



(i) It can be extracted only at limited sites where the wind blows most of the time in a year.
(ii) The minimum speed of wind should be 15 km/h.
(iii) Large area is required to build the wind farm/wind mills which is expensive affair.
(iv) Efficiency, is low.
