Geothermal technology harnesses the Earth's natural heat to generate energy. This heat comes from the Earth's core and can be found in hot springs, geysers, and underground reservoirs. By drilling wells into these areas, we can access steam or hot water, which can then be used to produce electricity or provide direct heating for homes and businesses. This renewable energy source is environmentally friendly and sustainable, as it produces very low greenhouse gas emissions. Countries like Iceland and the United States have successfully implemented geothermal systems, showcasing its potential to reduce reliance on fossil fuels and combat climate change.
