How Clean Is Geothermal Energy?

Earth’s heat powers geothermal energy, offering a sustainable electricity source with minimal environmental impact. Clean energy from thermal reservoirs produces significantly lower emissions compared to fossil fuels.

Geothermal plants generate baseload power consistently, making them reliable alternatives to traditional energy sources.

Let’s compare geothermal emissions to other energy sources:

• Coal: 820-1,000 g CO2e/kWh
• Natural Gas: 490 g CO2e/kWh
• Solar PV: 48 g CO2e/kWh
• Wind: 11-12 g CO2e/kWh
• Geothermal: 38 g CO2e/kWh

Eco-friendly heating from geothermal sources provides carbon-neutral options for various applications. Underground steam powers turbines, while binary cycle plants utilize lower-temperature resources. Direct use applications include district heating systems, greenhouse cultivation, and aquaculture. Balneology harnesses geothermal waters for therapeutic purposes.
Heat exchangers transfer thermal energy efficiently, enabling enhanced systems to maximize output. Dry steam technology and flash steam plants convert high-temperature resources into electricity. Ground source pumps utilize shallow earth temperatures for heating and cooling buildings.

Thermal Reservoirs: Nature’s Power Plants

Geothermal reservoirs harness Earth’s internal heat, offering sustainable electricity generation opportunities. These natural power plants come in various forms, each with unique characteristics and potential applications.
Types of geothermal reservoirs:
