Wind energy key advantage – UGC NET Question

Wind energy harnesses the kinetic energy of moving air using turbines connected to generators. During operation, this process does not involve combustion and therefore does not release carbon dioxide, sulphur dioxide, particulates or other typical power-plant pollutants. While there are impacts associated with manufacturing and installation, the operational emissions are very low compared with coal-based thermal power. Hence, the absence of direct greenhouse gas and air pollutant emissions during operation is a key environmental advantage.

Option A:
Option A is correct because it highlights the major environmental benefit of wind power, namely low operational emissions. This makes wind a critical component of strategies aiming to decarbonise electricity systems and reduce local air pollution.

Option B:
Option B is incorrect since wind farms do require land or offshore space for turbine placement and access roads. Land-use planning is an important consideration in wind-energy development.

Option C:
Option C is incorrect because wind turbines do not consume coal; they replace the need for coal-based electricity generation. Suggesting they use coal misunderstands the technology.

Option D:
Option D is incorrect as wind can blow at any time of day depending on local weather patterns. Wind availability is variable, but it is not restricted to nighttime.
