Question

Simone created a chart to summarize the energy transformations that take place when energy from the wind is used to generate electricity.

A 2-column table with 2 rows titled Energy from Windmills. The first column labeled Process has entries wind spins turbines, turbines activate generators. The second column labeled energy Energy transformation has entries ?, mechanical energy transformed to electrical energy.

Which best completes the chart?

nuclear energy transformed to electrical energy
chemical energy transformed to electrical energy
radiant energy transformed to mechanical energy
kinetic energy transformed to mechanical energy

Answer 1

Kinetic energy transformed to mechanical energy.

Reason: moving air (wind) has kinetic energy, and when it spins the turbine that kinetic energy becomes mechanical (rotational) energy, which the generator then converts to electrical energy.
