The amount of light pollution will decrease. The air conditioner at the school will run less often. Fewer natural resources will be used to make electricity. Money will be saved on the electricity bill for the school.
I gave my students this multiple choice question: A school replaced all of their light bulbs with a new type of light bulb. The new light bulbs use less energy. How will the new light bulbs most likely help the environment?

Only one answer is correct among these 4 choices:
- The amount of light pollution will decrease.
- The air conditioner at the school will run less often.
- Fewer natural resources will be used to make electricity.
- Money will be saved on the electricity bill for the school.

Could you tell me which one is correct?

Fewer natural resources will be used to make electricity.
