L'énergie géothermique, une source d'énergie renouvelable et durable, exploite la chaleur à l'intérieur de la croûte terrestre. Cette chaleur, générée par le noyau de la planète et la désintégration radioactive, se manifeste sous différentes formes :
1. Vapeur géothermique :
2. Eau chaude géothermique :
3. Conversion directe de la chaleur en énergie :
Avantages de l'énergie géothermique :
Défis de l'énergie géothermique :
Avenir de l'énergie géothermique :
L'énergie géothermique a un potentiel immense pour devenir un acteur plus important dans le mix énergétique mondial. La recherche et le développement en cours, en particulier dans les technologies de conversion directe de la chaleur en énergie, pourraient améliorer encore son efficacité et sa rentabilité. Alors que les préoccupations concernant le changement climatique s'intensifient, l'énergie géothermique est appelée à jouer un rôle crucial dans la transition vers un avenir énergétique plus propre et plus durable.
