<span>Affects of geothermal plants on the environment
</span> Although geothermal plants have many advantages over other conventional fossil fuels units such as it is a renewable resource, but it has many affects as well on the environment.
Forexample
Geothermal plants discharge approximately 6.5 times as much heat, 5.5 times as much water vapours, and 0.5 times as much sulfur per unit of power produces as would a coal plant.
They also release hydrogen sulfide, carbon dioxide, arsenic, and mercury at a concentration that have an adverse but not calamitous effects.
ground subsidence is acknowledged as a potential problem.
pollutant formation may be independent of the power production rate.
Effluent pathways may change abruptly generating hazards that have not been anticipated.
Pre-operational testing and random bore holes contribute negatively to the overall impact.
Waste water may be discharged at temperatures high enough so that utilization of the waste heat becomes both practical and imperative.
