Question

Describe one of the greatest drawbacks nto the extensive use of geothermal energy.

Answer 1

in many cases, a site that has happily been extracting steam and turning it into power for many years, may suddenly stop producing steam. This can happen and last for around 10 years in some cases.

Developers of such sites must be careful and aware that in some cases, harmful gases can escape from deep within the earth, through the holes drilled by the constructors. The plant must be able to contain any leaked gases, but disposing of the gas can be very tricky to do safely.
