The falling water (kinetic) turns the turbine, which turns a crank
on a generator (mechanical), causing it to produce electricity.

Energy Conversion Diagrams
Draw cross sections of the following topics, Hair dryer, wind turbine, car engine, riding a bike, water wheel, electric generator, light bulb, toasterThe cross section should include.
Be sure to include:
--A detailed diagram of how the structure works.
--A list of the specific energy conversions and where they occur

Conclusion Answer
The motor changes electrical
energy into mechanical energy
which converts into kinetic
energy as the fan blades move.
