Question

guided practice one drawback of wind - generated energy is that ______. a. energy cannot be stored b. winds are not constant c. aerogenerators are too lightweight d. spinning vanes are dangerous

Explanation:

Wind energy depends on consistent wind flow. Since wind speed and availability vary (due to weather, time of day, location), this inconsistency is a core drawback. Option A is incorrect because wind energy can be stored in batteries or converted to other storable forms. Option C is wrong as aerogenerators (wind turbines) are built to be heavy and sturdy. Option D is a minor concern compared to the fundamental issue of inconsistent wind supply.

Answer:

B. winds are not constant
