How are hydroelectric power stations built?
Firstly, the topographer makes a detailed study of the topography on the local, in which the hydroelectric power plant will be built. Then on an appropriate place the terrain is lowered to form the waterfall which will move the turbines that will generate electricity. The river is blocked to form a huge dam and it has a channel to make the water fall from the top of the dam. Many stages to be followed until the turbines begin to generate electricity.

Why can metals conduct electricity but remain unchanged?
Only the free valence electrons forming the electron "gas" move and as many move in as move out. Only metals form this electron "gas".
What is steam power made from?
Steam power could be described as pressure. Water heated above the boiling point turns to steam and the molecules move very rapidly and want to separate. If the water is in an enclosed area, the pressure will increase. This pressure can be used to move components of an engine that generates electricity. Generally, steam power is used to generate electricity or in the case of old railroad engines, it was used to actually push the train forward. Generally steam power isn't very efficient because you need an extreme source of heat to bring the water to boiling.
How does electricity pass through lead?
The same as it does in any metal. Metals have a number of electrons that can move about freely; these carry the current.
