# Geothermal Energy

## What is Geothermal Energy? 

Geothermal is a form of [renewable energy](https://www.cegal.com/en/dictionary/renewableenergy) harnessed from the heat stored beneath the earth's surface. It involves extracting and converting thermal energy from subsurface hot water and steam reservoirs, or directly from hot dry rock formations, into usable power for electricity generation, heating, and industrial applications.  

Geothermal energy systems typically include geothermal wells, heat exchangers, and turbines, designed for efficient energy capture and transfer. It offers a clean, virtually inexhaustible energy source and low operational costs. The scalability of geothermal systems supports diverse applications, from large power plants to localized heating solutions, fostering energy independence and resilience. 

Using geothermal energy sources significantly reduces greenhouse gas emissions compared to fossil fuels, contributing to climate change mitigation. Geothermal energy systems have a minimal environmental footprint, with low land and water usage, and they produce reliable base-load power, enhancing energy security and stability. By promoting geothermal energy, we can decrease dependency on non-renewable resources, reduce air pollution, and support long-term environmental health and resilience, aligning with global sustainability goals.
