List 3 disadvantages of geothermal energy and explain it in a point, example, explanation form best answer gets !

Disadvantages of geothermal energy:

1. Potential emissions

The greenhouse gas below the surface tends to move up to the surface and this emission of gas contains sulfur dioxide and silica which also have considerable amount of toxic heavy metals such as mercury, boron and arsenic.

2. Surface instability

Construction of a geothermal power plant is quite difficult. It affects the stability of the land. In 1997, while constructing a geothermal power plant in Switzerland causes an earthquake of magnitude 3.4.

3. Location specific

Good geothermal reservoirs are not found at every place and the prime locations for the power plant are far from the population centers.
