Wind Energy

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

Which answer best completes this sentence correctly? 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

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.
