Abstract:
The growing concern over climate change has prompted an intensified ex-
amination of sustainable energy sources, and geothermal energy is a promising can-
didate in this regard. This sustainable energy source, derived from the Earth's internal
heat, offers many advantages that position it as a viable solution for reducing green-
house gas emissions and transitioning towards a low-carbon future. Therefore, the
objectives of this systematic review were to (1) comprehensive synthesis of the exist-
ing body of research on the relationship between geothermal energy utilization and
its role in climate change mitigation, (2) explore the opportunities, challenges, and
potential outcomes associated with geothermal energy adoption and provide valuable
guidance for policymakers, researchers, and stakeholders invested in achieving a sus-
tainable and resilient energy future. We reviewed 50 scientific papers published from
2000 to 2022 using the Scopus search engine, and” climate change”, “geothermal en-
ergy”, “renewable energy and power” were the main keywords. We focused our
search on scientific articles written in English. The relationship between geothermal
energy utilization and its role in climate change mitigation was reviewed. Further, the
opportunities, challenges, and potential outcomes linked with adopting geothermal
energy and practices to achieve a sustainable and resilient energy future were ex-
plored. As a stable and renewable power source, geothermal energy reduces green-
house gas emissions (97%), helps decrease reliance on fossil fuels, and supports cli-
mate-resilient infrastructure. Compared to the fossil fuels, primary shared obstacles
to geothermal resources include high initial expenses, intricate and costly technolo-
gies, extended production periods, and significant financial risk without rewards.
Nevertheless, geothermal energy offers multiple advantages: it remains unaffected by
weather, exaggerated widespread accessibility, lacks geographical constraints, eco-
friendly, and cost-efficient. Geothermal energy has become a robust partner in the
global struggle against climate change.
