This is much lower return than the ...
Geothermal Heated Streets In Reykjavik Iceland
Reykjavik''s geothermal heated streets system was first implemented in the late 1990s and has been expanded over the years to cover a significant portion of the city''s road network. The system relies on low-temperature hot water, typically around 60°C (140°F), which is a byproduct of geothermal power plants.
How electricity is generated
Most U.S. and world electricity generation is from electric power plants that use a turbine to drive electricity generators. In a turbine generator, a moving fluid—water, steam, combustion gases, or air—pushes a series of blades mounted on a rotor shaft. The force of the fluid on the blades spins (rotates) the rotor shaft of a generator.
