It should be noted that it is often difficult to differentiate the man-made emissions from a geothermal power plant from the emissions that would occur naturally because of the natural geothermal activity of the site.
Opozoriti je treba, da je pogosto težko razlikovati med emisijami, ki jih povzroči človek z geotermalno elektrarno, in emisijami, ki bi nastale naravno zaradi naravne geotermalne dejavnosti na območju.
