What are wind farms and what do they do?

• It's a power plant.

• A bunch of wind turbines that generates power everywhere.

• A bunch of windmills that generates power everywhere

• A bunch of people that blow to create wind energy

True or False; Wind energy is the most expensive energy in the world

• True

• False

Wind energy is a renewable source of energy

• True

• False

• It is partially both renewable and nonrenewable

Malaysia doesn't harness wind for power generation. Why do you think that is?

• The technology is too expensive

• Lack of interest in renewable energy

• Inconsistent and erratic wind patterns

• Insufficient wind speeds

With wind-electric turbines, electric energy is turned into rotational energy.

• True

• False

The kinetic energy of the wind is transferred to the wind turbine blade

• and is changed to potential energy when it hits the wind turbine blade

• and the blade gains all the kinetic energy

• and the wind loses all its kinetic energy

• when the wind collides with the blade and the wind loses kinetic energy

Which answer best completes this sentence correctly? Wind turbines do not contribute to the enhanced greenhouse effect while they are being used because:

• wind turbines produce only a minimal amount of waste heat energy.

• wind turbines do not produce any carbon dioxide gas.

• wind turbines are very efficient.

• wind turbines do not damage the ozone layer.

There are two wind turbines of different designs. One has a small number of large blades, the other has a large number of small blades.

Predict which turbine will be the most efficient.

ie. Which turbine will produce the most electricity?

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 going around the blades, pulls them along
