All Flashcards
What is geothermal energy?
Renewable energy from Earth's internal heat.
Define geothermal power plant.
Facility using underground hot water/steam to generate electricity.
Define geothermal heat pump.
System using stable Earth temperature to heat/cool buildings.
What is a renewable resource?
A resource that can be replenished naturally over time.
What is a closed-loop system (in geothermal context)?
Cooled water is pumped back into the Earth after use.
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 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
