Which option lists methods for conserving energy on a large scale?

• A. Deteriorating building design features.
• B. Improving fuel economy for transportation, using battery electric and hybrid vehicles, using public transportation, and implementing green building design features.
• C. Building more coal plants.
• D. Increasing personal energy consumption.

Answer: (B)

The main idea is reducing energy use across society by boosting efficiency and shifting to low-energy options. On a large scale, conserving energy means cutting overall demand through smarter transportation and building practices. This option fits best because it combines several proven strategies that lower energy use: improving fuel economy so each mile costs less energy, adopting battery electric and hybrid vehicles which use less energy per mile, riding public transportation to move more people with less energy, and applying green building designs that cut energy needs for heating, cooling, and powering a structure. Deteriorating building design features would raise energy losses and increase consumption, not conserve. Building more coal plants increases energy supply but not energy conservation, and it typically raises emissions. Increasing personal energy consumption directly works against conserving energy.
