Which factor is NOT a consequence of extreme weather on the electrical grid?

Extreme weather events can have a profound impact on the electrical grid, leading to various challenges and consequences. Among the choices presented, the factor that stands out as not being a consequence of extreme weather on the electrical grid is improved grid efficiency.

In fact, extreme weather typically does the opposite, causing increased demand for electricity due to factors such as elevated temperatures requiring more cooling or severe weather resulting in heating needs. Additionally, such weather can lead to significant damage to infrastructure, including power lines and substations, resulting in outages and reduced reliability. Furthermore, disruptions to supply networks can occur, making it difficult to maintain a balanced flow of electricity and affecting overall grid stability.

Therefore, the idea that extreme weather improves grid efficiency contradicts the typical impacts observed, making it the correct choice for what is not a consequence of extreme weather on the electrical grid.
