Contrasted with intermittent renewables like solar and wind, geothermal is firm, or ‘baseload’, meaning it is always on, and does not require energy storage to operate. In this way, geothermal plays the same role on the grid as coal, nuclear, and natural gas.
Geothermal has the Smallest Footprint Compared to Other Energy Sources
Geothermal has the lowest lifecycle carbon emissions, smallest land footprint, and lowest water contamination concerns of all energy technologies including solar, nuclear, wind, fossil fuels, and battery storage. Geothermal operations are also weather and attack resilient, since much of the footprint of geothermal operations are located underground.
