Marktübersicht
Geothermie, die aus der in der Erdkruste gespeicherten Wärme gewonnen wird, hat sich als eine der zuverlässigsten erneuerbaren Energiequellen erwiesen. Im Gegensatz zu Solar- oder Windenergie bietet Geothermie eine rund um die Uhr verfügbare Stromerzeugung mit minimalen Schwankungen und ist damit eine zuverlässige Ergänzung zu anderen erneuerbaren Energiequellen.
Das Marktwachstum wird durch die zunehmende Besorgnis über Treibhausgasemissionen, den steigenden Strombedarf und die zunehmende Nutzung erneuerbarer Technologien durch Regierungen weltweit vorangetrieben. Darüber hinaus erweitern technologische Fortschritte bei Bohrtechniken, Reservoirmanagement und binären Kreislaufkraftwerken das geothermische Potenzial über traditionelle Regionen hinaus.
