The article discusses how different regions of the world use geothermal energy based on their geological features. Countries like the United States, the Philippines, and Mexico are leading in geothermal energy production. Geothermal energy is mainly used for heating buildings, water, and industrial processes. For example, in Beijing, geothermal wells provide hot water for heating buildings and greenhouses. In Iceland, most of the country's heating needs are met by geothermal energy. Overall, geothermal energy is only used for 0.5% of global electricity generation, but it has great potential for sustainable energy production.
