All Flashcards
What is the effect of drilling for geothermal resources on land stability?
Can cause land subsidence or trigger seismic activity in certain areas.
What is the effect of releasing hydrogen sulfide from geothermal plants?
It can cause air pollution and has a distinct, unpleasant odor.
What is the impact of geothermal energy on greenhouse gas emissions compared to fossil fuels?
Generally lower emissions, but some methane and carbon dioxide can still be released.
How does geothermal energy promote sustainability?
Provides renewable energy source, reduces fossil fuel dependence.
How does reinjecting water promote sustainability?
Maintains reservoir pressure, reduces water waste.
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.
