Question

Quizplus · Accepted Answer

Installing efficient geothermal systems to cool homes in the summer would directly reduce the demand for electric power, as air conditioning is a significant contributor to peak electricity demand in the summer months. Increasing the number of hybrid cars (B) may reduce demand for gasoline, but it wouldn't directly impact electricity demand. Adopting policies to promote salmon migrations (C) would have little to no impact on electricity demand. Requiring companies to turn off lights on weekends (D) may reduce electricity consumption somewhat, but it wouldn't have as significant an impact as installing efficient geothermal systems.
