What is one major drawback of geothermal energy?

One major drawback of geothermal energy is that it is primarily feasible in volcanic regions or areas with significant tectonic activity. This limitation arises because geothermal energy relies on the Earth's heat, which is more accessible in locations where geological conditions allow for the efficient extraction of thermal energy. Regions with active geothermal features, such as hot springs or geysers, are ideal for harnessing this energy. Therefore, the geographical constraints mean that not all areas can take advantage of geothermal resources, which limits the widespread applicability of this type of energy on a global scale.

The other options have their own contexts: while geothermal energy is considered renewable, it does not inherently lead to high greenhouse gas emissions like fossil fuels do, and it typically does not require vast amounts of land compared to some other renewable energy sources such as wind or solar.
