Wind Power Basics
This is moving air that can push objects.
wind
This machine turns motion into electrical energy.
generator
Old windmills were used to turn grain into this.
flour
This type of energy powers lights and video games.
electricity
Using resources so there is enough for the future is called this.
sustainability
The layer of air around Earth
atmosphere
This machine turns motion into electrical energy.
generator
Old windmills were used to pump this.
water
Electricity travels through these to reach homes.
wires
Wind energy is clean because it does not produce this.
pollution
This word means something that spins around a center point.
rotation
When wind spins blades, it causes this motion.
rotation
Modern wind machines are called this.
turbines
The generator changes motion into this kind of energy.
electrical energy
Wind energy is good for the Earth because it is a _______ energy source.
renewable
Wind is an example of this type of energy because it can be replaced quickly.
renewable energy
A group of parts working together is called this.
system
Modern turbines use generators to make this.
electricity
Wind energy helps reduce the use of this harmful energy source, that comes from animals and plants that died millions of years ago.
fossil fuels
Name one natural source of energy like wind.
sun, water, or geothermal
Wind uses this kind of force to move things.
A. Heat force
B. Mechanical force
C. Light energy
D. Sound energy
Mechanical force
Just like water pushes a water wheel, wind pushes this part to create energy.
turbine (or blades)
Which is more efficient at making electricity: old windmills or modern turbines?
modern turbines
This happens when energy changes from one form to another.
transformation
Why is wind energy important for the future?
clean, renewable, sustainable
