Energetska kriza često prisutna u različitim oblicima, stvara prostora za korištenje „manje značajnih“  vidova energije. Jedan od tih vidova energije je geotermalna energija, koja se može koristiti u mjestu njenog postojanja, za različite energetske svrhe. Veoma je prihvatljiva i najčešće povoljnije cijene u odnosu na komercijalne vidove energ...
