Question 5:

Which of the following is a challenge in the integration of intermittent renewable energy sources into the grid?

A) High predictability of energy output
B) Low potential for storage technologies
C) Inadequate renewable energy resources
D) Reduced grid stability and reliability

Show Answer

Explanation: The correct answer is D) Reduced grid stability and reliability. One of the challenges in the integration of intermittent renewable energy sources, such as solar and wind, into the grid is the variability and intermittency of their energy output. This can result in fluctuations in power supply, making it necessary to balance supply and demand, enhance grid flexibility, and develop energy storage and grid management technologies to ensure grid stability and reliability.
