The diagram below shows a simple set-up of a hydro-electric power station. The water turns the blades in the turbine so that electricity is produced by the generator to light up the bulb. In the
set-up, energy changes take place to produce electrical energy.

Fill in the blanks according to the info provided.
[ ] energy of water at A -> [ ] energy of water at B -> [ ] energy of generator at C.
