Show answer & explanation
Correct answer: B
CONCEPT
Renewable-energy technologies use naturally replenished flows. Wind turbines convert the kinetic energy of moving air into electricity, so their output follows the availability and speed of wind.
Wind power has low operational emissions, but clean energy does not mean zero environmental effect. Location and design can create wildlife, land-use, noise, and visual impacts.
APPLICATION
Apply these principles to the five statements:
Statement A describes variable wind availability, so wind generation is intermittent.
Statement B reflects that small or distributed wind systems can supply remote and isolated places where grid extension is difficult.
Statement C conflicts with the operating mechanism: turbine output depends directly on wind conditions and therefore on weather.
Statement D reflects electricity generation without fuel combustion during operation, which is why wind is classified as clean energy.
Statement E is absolute and overlooks site-specific effects such as bird and bat collisions, noise, visual change, and land use.
CROSS-CHECK / CONTRAST
The supported statements are A, B, and D; C reverses wind dependence, while E turns a low-impact claim into an unsupported zero-impact claim.
RESULT
Therefore, the most appropriate set is A, B, D only.
