Question

which energy source has no greenhouse gas emissions or health impacts on humans, but is only available in certain geographic locations?
a. geothermal power
b. nuclear power
c. hydrogen fuel
d. natural gas

Explanation:

• Geothermal power uses underground heat, has minimal greenhouse gas emissions, but is only viable in specific geographic locations (like tectonically active areas with accessible underground heat reservoirs).
• Nuclear power has low emissions but carries health risks from radiation and is not limited to specific locations.
• Hydrogen fuel can be produced anywhere with inputs, and while it has no tailpipe emissions, production may involve emissions depending on the method.
• Natural gas is a fossil fuel with significant greenhouse gas emissions and is widely accessible via infrastructure.

Answer:

A. geothermal power
