Wind is an inexhaustible source of energy and aerogenerator can convert it into electricity. Through not much has
so far been done in this field, the survey shows that there is a vast potential for developing wind as an alternative
source of energy. The wind survey has four components -- direction, duration, speed and distribution.
On this basis U P. hill areas have been found an ideal place for setting up aerogenerators. In U.P. hills alone, as
many as 58 sites have been identified.
Wind, as a source of energy, can replace exhaustible sources of energy.
Answer: D
According to the passage, wind is an inexhaustible source of energy and efforts are being made to develop wind as an alternative source of energy. This clearly implies the given fact.
