Geothermal energy is a renewable and sustainable energy source derived from the natural heat within the Earth's interior. It can be used for heating or electricity generation. Geothermal energy is virtually inexhaustible, making it an environmentally friendly alternative to fossil fuels, as it emits minimal amounts of greenhouse gases. Since it provides a consistent energy supply regardless of weather conditions, geothermal energy is a reliable resource that plays a vital role in reducing carbon dioxide emissions and combating climate change.
