Passage Summary: It is so hot that everyone's air conditioning is crashing the power grid. Even if people try to use less AC at home, the experts think the power will still keep going out.

Reasoning: The region's power grid is currently overloaded by air conditioner use during a heat wave, and even if residents voluntarily reduce their usage, blackouts are still expected to continue.

Analysis: We are faced with a situation where a proposed solution—voluntary residential cutbacks—is predicted to fail. To resolve this paradox, we need to find a reason why these cutbacks aren't enough to stabilize the grid. Perhaps residential use is only a small fraction of total energy consumption, or maybe the heat wave is so intense that the hardware itself is failing regardless of the load. Look for an answer that introduces a factor the residents can't control.
