-A geothermal heat pump is measured in coefficient of performance (COP), meaning that if the heat pump is operating at COP 4.0 during a heating season it will provide 4 units of heat for each unit of energy consumed. For each dollar spent on energy, you will receive 4 dollars back.

- CO2 and CH4 are greenhouse gases that contribute to global warming

- H2S, when released into the atmosphere, reacts to become SO2, which contributes to acid rain

- Land subsidence can occur as a result of pumping groundwater; this is an event in which the ground level sinks beneath the norm due to instability - increased seismic activity can also occur

- Chemicals used for geothermal power plants are generally pumped back into the earth, which stimulates production and reduces threats to the environment - to the effect of decreasing exposure - but this can create groundwater contamination

-Flash steam power plants: hot water pumped to service, reduces pressure quickly to produce a blast of steam

-Binary cycle power plants: Used to get energy from geothermal reservoirs that are too cool to create steam. Water is pumped  to the surface and passes through a heat exchanger with a liquid with a lower boiling point than water. The heat from the water causes the other liquid to turn into steam, spinning the turbine.
