Does geothermal energy smell

Answer 1

If by geothermal energy, you are referring to electricity produced using geothermal energy, no it doesn't smell, because energy in any form doesn't smell.

On the other hand, a geothermal power plant may give off a "rotten eggs" smell. This is due to hydrogen sulfide being present in the steam collected from the geothermal reservoir. Although the hydrogen sulfide is treated to reduce it to non-toxic levels, hydrogen sulfide can be smelled at levels as low as a few parts per billion. Since geothermal plants won't always be able to remove all of the hydrogen sulfide, some will be released, accounting for the smell.
