Geothermal Power
What is energy from the Earth's heat?
What is geothermal power?
What is energy from moving water
What is hydropower?
This gives energy to solar panels
What is the Sun?
Tidal energy comes from the rising and falling of these.
What are ocean tides?
Wave power uses the energy from these moving on the ocean.
What are waves?
What’s the difference between dry steam, flash steam, and binary cycle plants?
Dry Steam: Uses steam directly from the Earth.
Flash Steam: Uses hot water that turns into steam when pressure is lowered.
Binary Cycle: Uses heat to warm another liquid that turns into steam.
What’s the difference between a dam and a run-of-river?
Dam: Stores water.
Run-of-River: Uses water directly.
These panels go on roofs to make electricity from sunlight.
What are solar panels?
Tides are caused mostly by the pull of this space object.
What is the Moon?
Waves are mostly made by this moving over the water.
What is wind?
How does the Earth’s temperature affect geothermal energy?
The hotter the Earth, the more energy it can make?
How does the height of water affect energy?
The higher the water falls, the more energy it makes?
Solar power is a type of this energy that doesn’t run out.
What is renewable energy?
Tidal power is strong when this difference is large.
What is the tidal range (or difference between high and low tide)?
Some wave machines float and move up and down to make power.
What is a point absorber?
What are the risks of geothermal energy?
Small earthquakes,
Water pollution?
What are some impacts of hydropower?
Blocking fish,
Changing water flow,
Flooding land
This tool changes the electricity from solar panels so it works in homes.
What is an inverter?
A tidal barrage works kind of like this water-blocking structure.
What is a dam?
It’s hard to build wave machines because oceans have this kind of weather.
What are storms?
What are the challenges of deep geothermal energy?
Expensive to drill,
Equipment may break?
What is pumped storage hydropower?
When water is stored, then used to make power later?
A big solar plant uses these to reflect sunlight to one point.
What are mirrors (or heliostats)?
This country built one of the first big tidal power plants.
What is France?
This country has a big wave energy test site in Orkney.
What is Scotland?
