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.
Why is geothermal energy considered a renewable resource?
The Earth continuously produces heat, making it a resource that replenishes itself.
How does geothermal energy contribute to reducing reliance on fossil fuels?
It provides an alternative energy source that doesn't depend on finite fossil fuel reserves.
Explain the concept of a closed-loop system in geothermal power plants.
Cooled water is pumped back into the Earth after use, minimizing water waste and environmental impact.
What is the role of a turbine in a geothermal power plant?
The turbine is spun by steam, converting thermal energy into mechanical energy, which then generates electricity.
Explain why geothermal energy is location-dependent.
Geothermal resources are not evenly distributed; they are concentrated in areas with volcanic activity or tectonic plate boundaries.
What are the primary sources of heat within the Earth that contribute to geothermal energy?
Radioactive decay of materials in the Earth's core and residual heat from the planet's formation.
