Geothermal power is a clean source of renewable energy. In Iceland, we're blessed with an abundance of naturally-warm sources of water which we use e.g. for house heating and for our swimming pools like Akureyri Geothermal Pool. We recommend you to visit it on your next visit and find out how good effects it has on you mind, body and soul.
