All Flashcards
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.
Why is geothermal energy considered renewable?
Earth continuously produces internal heat.
How do geothermal power plants access heat?
Wells drilled to underground hot water/steam reservoirs.
What drives the turbine in a geothermal plant?
Steam from heated water spins the turbine.
What heats the water in geothermal reservoirs?
Earth's core heat, radioactive decay, residual heat.
What is the environmental benefit of geothermal energy?
Reduced reliance on fossil fuels, low emissions during operation.
What are the limitations of geothermal energy?
Expensive to build, location limitations, releases some GHGs.
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.
