Solar captures the constant energy from the sun's nuclear fusion using photovoltaic panels. Geothermal taps into the massive amount of heat within the Earth that's been building up over billions of years and uses the steam to run turbine generators. Geothermal heating and cooling technologies offer clean, efficient temperature control. . A Stanford study finds that adding geothermal power cuts wind, solar, and battery capacity requirements while keeping energy costs low. Enhanced geothermal systems could provide constant, low-cost, clean electricity while reducing land use and infrastructure needs in a global renewable energy. .

Geothermal energy draws on natural underground heat to make electricity, heat and cool buildings, or provide heat and steam for manufacturing. Like solar and wind power, this energy is clean and renewable. Wells ranging from a few feet to several miles deep can be drilled into. . A Stanford study finds that adding geothermal power cuts wind, solar, and battery capacity requirements while keeping energy costs low. But unlike solar and wind, it is also “firm”: available day in and day out, no matter the. . A new analysis from Oak Ridge National Laboratory (ORNL) and the National Renewable Energy Laboratory (NREL) found that, coupled with building envelope improvements, installing geothermal heat pumps in around 70% of U. buildings could save as much as 593 terawatt-hours of electricity generation. .
