All Flashcards
What is the effect of drilling for geothermal energy?
Potential land disturbance during construction.
What is the effect of using geothermal energy?
Reduced reliance on fossil fuels.
What is the effect of pressure drop on hot water?
Causes it to flash into steam.
What are the effect of geothermal power plants?
Releases hydrogen sulfide and methane
How can reinjection of cooled water enhance the sustainability of geothermal energy?
Replenishes the geothermal reservoir, extending its lifespan and reducing water waste.
How can improved drilling techniques contribute to the sustainability of geothermal energy?
Minimizes land disturbance, reduces the risk of induced seismicity, and improves access to geothermal resources.
What are the steps in geothermal electricity generation?
Deep well → Hot water/steam → Turbine → Electricity → Cooling → Back to Earth.
Outline the process of accessing geothermal energy.
Drill wells, pump hot water/steam to surface under pressure.
How is electricity generated from geothermal sources?
Steam spins a turbine connected to a generator.
What happens to the steam after it spins the turbine?
Cooled, condensed into water, pumped back into Earth.
