Before the electricity can be generated, conduits between geothermal reservoirs and the Earth's surface must be provided. This is done by drilling production and injection wells.
During the drilling process, a special drilling mud is used to prevent the well from collapse. A metal pipe is then installed inside the well to allow the steam and water to travel to the surface.
At the top of the well, a master valve is connected together with pipelines that will carry the water and steam to the power station.
Geothermal Energy and The Environment
Unlike fossil fuelled power plants, no smoke is emitted; only steam is emitted from geothermal power plants.
Emissions of nitrous oxide, hydrogen sulfide, sulfur dioxide, particulate matter, and carbon dioxide are extremely low, especially when compared to fossil fuel emissions.
Geothermal power plants have been built in deserts, in the middle of crops, and in mountain forests. Geothermal plants produce almost no emissions because they do not burn fuel to generate electricity.
