La energía geotérmica

Geothermal energy, a heat source hotter than the Sun's surface, is generated by radioactive decay in the Earth's magma. It produces significantly more energy than fossil fuels but is accessible only in specific geological locations. Iceland effectively utilizes geothermal energy for heating and electricity, with power plants emitting minimal carbon dioxide. Technological advancements may enhance geothermal energy's role in sustainable energy solutions.
