Possible sources of geothermal pollution how we can avoid it
Answers
Thermal pollution is the degradation of water quality by any process that changes ambient water temperature. Geothermal energy is the naturally occurring thermal energy that is produced by the Earth's molten inner core.
Geothermal energy can be used in two main applications. The first is on a large scale generation of electricity and using the resulting steam to drive turbines. The second is on a building or household scale to supply heat from ground to home and vice versa for air conditioning and heating purposes by using a loop of tubing that goes into the ground.
Geothermal electricity generation does involve a small amount of geothermal pollution in that the steam coming up from below ground carries some toxic gases, but in most plants, these gases, as well as the steam, are condensed and reinjected into the ground so the effect on the environment is negligible. There are no CO2 emissions from geothermal energy so it is a much better source of electricity than coal or natural gas or nuclear (or even large-scale hydro generation which requires the flooding of large areas of land).
Answer:
A few steps that can be taken to ensure little or no geothermal pollution are using less electricity, reduce temperature and volume of discharge, storing and reusing heated water, and discharging the wastes in less vulnerable zones
