All Flashcards
What are the steps in geothermal electricity generation?
Drill wells, extract hot water/steam, spin turbine, generate electricity, cool steam, return water to Earth.
Describe the process of using geothermal heat pumps for building climate control.
Circulate fluid through underground pipes, absorb/release heat from/to the Earth, transfer heat to/from building.
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.
Define geothermal energy.
Renewable energy from Earth's internal heat, used for electricity, heating, and cooling.
What are geothermal power plants?
Facilities that tap into underground hot water or steam reservoirs to generate electricity.
What are geothermal heat pumps?
Systems that use the Earth's stable temperature to heat and cool buildings.
Define renewable energy.
Energy from sources that are naturally replenished, such as geothermal, solar, and wind.
