What steps are involved in the production of hydroelectric power?

water falls down a pipe to generate electricity.

moving water turns a paddle wheel that generate electricity.

falling water turns a turbine that generate electricity.

potential energy of water is directly transformed into electrical energy.

I would say C.) Falling water turns a turbine that helps generate electricity.  The falling water is able to move faster if it is falling down.  When it is falling down it goes faster when it hits the turbine it is able to help generate power more efficiently.

I think it’s the 3rd option.
