The electricity is transmitted to end users through transformer towers and along transmission lines.
To heat or cool a building using geothermal energy, heat pump systems transmit warm or cool fluid along pipes throughout the structure and transfer it back through pipes to a body of water or into the ground.
To generate electricity with geothermal energy, wells are drilled, similar to oil extraction. Operators use a production well to drill down into the ground to access the warm water. An injection well is usually also installed, to return the water to underground reservoirs after it has gone through the power generation process at the plant. Geothermal power plants use equipment similar to that used in more traditional plants, including turbines, generators and transformers.
Like other plants that use turbines to create electricity, geothermal energy is transmitted to end users from the plants through transformer towers and along transmission lines long distances to community substations.
