WIND POWER

• Where the wind velocity is more than 32 kmph, wind mills can be used for lifting water.
• Experimental results show that a wind mill having 3.6 diameter wheel mounted on 12.0 m tower is able to produce from 0.1 to 0.9 hp with the wind velocity varying from 6.4 to 37 km/h.
• Thus, the average capacity of a wind mill would be about 0.50 hp.

Disadvantages

• Initial investment is high,
• Repair facilities are not available in rural areas,
• Even the matching pump sets and electric generators are not readily available in the country
• It not suitable for all situations in the country.
