To enhance technological efficiency for reducing power consumption, which sectors should be prioritized?

The correct answer highlights the importance of prioritizing the residential and commercial sectors to enhance technological efficiency for reducing power consumption. The residential sector involves a significant amount of energy use, primarily due to heating, cooling, lighting, and powering appliances. By improving the efficiency of homes—through better insulation, energy-efficient appliances, and smart technology—substantial reductions in power consumption can be achieved.

Similarly, the commercial sector encompasses offices, stores, and other buildings that also consume large amounts of energy for heating, cooling, and electronics. Implementing energy-efficient practices, such as retrofitting buildings to be more energy-efficient, adopting LED lighting, and utilizing smart building technologies, can lead to significant savings in energy use.

Focusing on these two sectors can provide an immediate and impactful way to reduce overall power consumption levels in society, given their collective contribution to energy demands. While the other sectors, such as industrial and transportation, also require attention for efficiency improvements, the residential and commercial sectors provide a broader opportunity for widespread change and influence on both consumer behavior and market trends toward energy-saving technologies.
