Geothermal sustainability

Geothermal sustainability refers to the ability to use Earth's internal heat for energy without depleting or damaging the resource. Since the Earth's heat naturally replenishes over time, geothermal energy can be a reliable, low-impact source if managed carefully. Sustainable practices involve monitoring reservoir pressure and temperature, re-injecting cooled fluids, and avoiding over-extraction. When properly maintained, geothermal systems can provide clean, stable power for decades, making them a dependable part of a balanced energy mix while preserving the Earth's heat balance for future generations.
