What are the main challenges associated with wind energy?

  1. Intermittency

  2. High cost

  3. Visual impact

  4. Noise pollution


Correct Option:
Explanation:

Wind energy is intermittent, meaning that it is not always available when it is needed. It can also be expensive to install and maintain wind turbines. Additionally, wind turbines can have a visual impact on the landscape and can generate noise pollution.

How can the intermittency of wind energy be addressed?

  1. Energy storage

  2. Demand response

  3. Grid integration

  4. All of the above


Correct Option: D
Explanation:

The intermittency of wind energy can be addressed through a combination of energy storage, demand response, and grid integration.
