Wind energy is considered renewable because:
wind turbines can be easily replaced
no carbon dioxide or water vapour is produced during operation
no waste heat energy is produced
there is a continuing supply of wind energy
Windmills and wind turbines move because:
warm air rises against the blades
convection currents push air onto the blades
moving air pushes on the blade, slowing the air
moving air travels around the blades, pulling them along
When the kinetic energy of wind hits the wind turbine blade___
the energy changes into potential energy
the blade gains all the kinetic energy
the wind loses all its kinetic energy
the wind loses kinetic energy
A flow chart that shows the energy transformation occurring in a wind turbine
is best represented by:
heat energy → electrical energy + sound energy
gravitational potential energy → electrical energy + heat energy + sound energy
solar energy → electrical energy + heat energy + sound energy
kinetic energy → electrical energy + heat energy + sound energy
_____ changes wind energy into electricity.
Windmill
Windsock
Wind Turbine

what does a wind turbine look like
What is the force that propels an object upward, or at a right angle to the direction of the air stream?
Stream force
Drag force
Lift force
Air force
What do wind turbines, hydro electric dams, and ethanol plants have in common
All produce electrical current without pollution
All use generators to produce electrical current
All convert gravitational potential energy to electric current
All convert thermal energy to electrical energy
What is Rotational Energy?
