Unleashing the Power Beneath: A Dive into Geothermal Energy

Introduction

In the quest for sustainable and renewable energy sources, geothermal energy emerges as a formidable contender. It’s a natural source of power harnessed from the Earth’s internal heat. This article delves into the world of geothermal energy, exploring its applications, benefits, and the role it plays in driving the green revolution.

What is Geothermal Energy?

Geothermal energy is derived from the Earth's natural heat. This heat originates from the planet's core and is transferred to the surface through various geological processes. Unlike solar or wind energy, geothermal energy is not dependent on weather conditions, making it a reliable and consistent energy source.
