Question

question 5 of 10
what makes solar energy \green\?

a. it is cheaper than nuclear power.

b. it does not pollute the air.

c. it does not work at night.

d. it does not require any work.

Explanation:

"Green" energy refers to environmentally friendly energy. Solar energy is considered green because it produces electricity without emitting pollutants into the air (unlike fossil fuels). Option A (cost vs nuclear) isn't about environmental friendliness. Option C (doesn't work at night) is a limitation, not a green feature. Option D is incorrect as solar energy systems require setup/maintenance. So B is correct as it relates to environmental cleanliness.

Answer:

B. It does not pollute the air.
