Geothermal heating plants use which energy source?

Geothermal heating plants use which energy source?

• A. Solar
• B. Geothermal
• C. Biomass
• D. Wind

Answer: (B)

Geothermal energy is the heat stored beneath the Earth's surface that can be tapped to warm buildings. In a geothermal heating plant, hot water or steam from underground reservoirs or hot rocks is brought to the surface and used to transfer heat into buildings, often through a heat pump or a direct heat exchanger. This relies on the Earth's internal heat rather than energy from the sun, wind, or organic matter. Solar would require sunlight to generate heat, biomass uses burning organic material, and wind relies on moving air to capture energy. None of those sources is what geothermal heating plants draw from, which is why geothermal energy is the appropriate answer.
