Geo significaterra e térmica está ligada à quantidade de calor.Devido a natureza, a energia geotérmica é uma das mais benignas fontes deeletricidade. Essa energia é de obtenção mais barata que os combustíveisfósseis ou usinas nucleares. A emissão de gases poluentes é praticamente nula. A energia geotérmica é restrita, não sendo encontrada em todos os lugares, oque dificulta a implantação de projetos em determinadas localidades.
PERSPECTIVAS FUTURASA energia geotérmica é uma fonte de energia alternativa que é encontrada emlocais especiais da superfície terrestre, que necessita de muita pesquisa paramelhor ser aproveitada, pois o rendimento que se consegue é ainda muitobaixo. O alto custo das construções das usinas, da perfuração, e os possíveisimpactos inviabilizam ainda muitos projetos.
