How is electricity made?

Question

Could we ever run out of it?

Answer 1

Electricity results from the movement of electrons from the negative pole of a source (e.g. battery) to the positive.

As long as there is movement, electricity can be "created"; e.g. fast flowing water (dams), wind (windmills) ...

Sun light (solar energy) can also be used.

Of course, currently, most countries still rely on the burning of coal to run turbines so as to generate electricity.

Answer 2

Electricity is made by converting kinetic or potential energy into electrical energy. When a magnet moves over a conductor, electrical charge is generated.

Potential energy that is in oil and coal is burned to create steam which pushes a magnet around the conductor.

Kinetic energy of moving water does the same thing as the steam above.

We can only run out of sources to convert, however, we have so many sources of seemingly never ending energy: Sun, Water, Nuclear, and Wind to name a few.
