Question

question 16 of 26 how are geothermal and hydroelectric energy similar? a. they both produce greenhouse gases. b. they both use the motion of rivers to produce electricity. c. they are both nonrenewable energy sources. d. they both use turbines to produce electricity.

Explanation:

• Option A: Geothermal and hydroelectric energy are clean energy sources and do not produce significant greenhouse gases, so A is incorrect.
• Option B: Geothermal energy uses heat from the Earth's interior, not the motion of rivers. Hydroelectric uses river motion, so B is incorrect.
• Option C: Both geothermal (if using sustainable reservoirs) and hydroelectric are renewable energy sources, so C is incorrect.
• Option D: Geothermal energy systems use turbines (driven by steam from geothermal heat) and hydroelectric plants use turbines (driven by water flow) to generate electricity. So D is correct.

Answer:

D. They both use turbines to produce electricity.
