Question

review it!
enhanced geothermal systems (egs) actively inject cool or cold water into wells to be heated and pumped back out.
select the statement(s) that accurately describes how egs will increase the availability of geothermal power.
egs have a small land footprint.
egs requires less water than a hydroelectric plant.
egs increases the temperature underground.
egs have a small emissions output.
egs increases hydrothermal energy sources.

Explanation:

• EGS uses a closed-loop (or targeted well) system, so it has a small land footprint compared to many energy sources, which helps expand where geothermal can be used.
• EGS recirculates most of its water, so it uses far less water than hydroelectric plants that rely on large reservoirs/flow, making it feasible in more areas.
• EGS operates with minimal combustion or chemical processes, leading to small emissions output, which does not limit its deployment like high-emission sources, and supports wider use.
• EGS does not increase underground temperature; it uses existing geothermal heat. It also does not increase hydrothermal sources, as it is engineered to work in areas without natural hydrothermal reservoirs.

Answer:

EGS have a small land footprint.
EGS requires less water than a hydroelectric plant.
EGS have a small emissions output.
