Wind Energy

Wind is what type of energy?

• Renewable

• Non-Renewable

• Both renewable and non-renewable

Wind energy is considered renewable because:

• wind turbines can be easily replaced.

• no carbon dioxide or water vapour is produced during operation.

• there is a continuing supply of wind energy.

• no waste heat energy is produced.

How can wind become energy?

• When a windmill goes fast enough.

• When a wind turbine converts wind's energy into electricity.

• The sun heats it, so it becomes solar energy.

• It just naturally is.

How do wind turbines affect the environment?

(multiple correct answers)

• Cuts the clouds which affects the water cycle.

• Produces noise pollution.

• Can harm birds and other wildlife.

• Hits trees around them which blows up the wind turbine.

Answer explanation

Wind turbines can produce noise, which is a form of environmental impact. Depending on the specific location and design of the wind turbines, noise pollution can be a concern.

While wind turbines have environmental benefits, they can also pose risks to wildlife, particularly birds and bats.

Which answer best completes this sentence correctly?

A flow chart that shows the energy transformation occurring in a wind turbine is best represented by:

• solar energy → electrical energy + heat energy + sound energy

• heat energy → electrical energy + sound energy

• gravitational potential energy → electrical energy + heat energy + sound energy

• kinetic energy → electrical energy + heat energy + sound 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 do not produce any carbon dioxide gas.

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

• wind turbines do not damage the ozone layer.

• wind turbines are very efficient.
