Question

energy source
pros

• easy to use
• cost of using is low
• does not add to global warming

cons

• cost of security is high
• creates radioactive waste
• exposure can cause cancer

which source of energy does the table describe?

• coal
• geothermal
• natural gas
• nuclear

Explanation:

• Coal: Burns to release CO₂ (adds to global warming), so pros don't match.
• Geothermal: No radioactive waste or cancer risk from exposure, cons don't match.
• Natural Gas: Burns to release greenhouse gases (adds to global warming), pros don't match.
• Nuclear: Easy to use in power plants, low operational cost, no greenhouse gas emissions (doesn't add to global warming). Cons include high security costs (due to nuclear materials), radioactive waste production, and radiation exposure causing cancer. This matches the table.

Answer:

D. Nuclear
