Which of the following is NOT listed as an advantage of geothermal energy?

• A. Cost effective
• B. Reliable
• C. Weather stability
• D. Environmentally friendly

Answer: (C)

Geothermal energy is valued for its reliability, low operating costs, and low environmental impact. It provides a steady, baseload supply because it taps heat from the Earth, which isn’t tied to the weather in the same way as solar or wind. These characteristics are the ones most commonly highlighted as advantages: it can run consistently, it usually has lower fuel costs over time, and it emits very little pollution.

The phrase weather stability isn’t typically listed as a distinct advantage in standard summaries. The stability of geothermal output is usually discussed in terms of reliability or baseload capability, and the weather-related benefits are more characteristic of solar or wind energy. Because of that, weather stability isn’t treated as a separate listed advantage, making it the one option that doesn’t fit the typical list.
