Question

which energy source has no greenhouse gas emissions but has waste products that present a health hazard for humans?
a. geothermal
b. petroleum
c. nuclear
d. coal

Explanation:

• Petroleum and coal are fossil fuels that release large amounts of greenhouse gases (like CO₂) when burned, so they are eliminated.
• Geothermal energy produces minimal greenhouse gas emissions, but its waste products are generally not a major health hazard.
• Nuclear energy generates no greenhouse gas emissions during operation, but its radioactive waste products pose a serious, long-term health hazard to humans if not managed properly.

Answer:

C. nuclear
