ELECTRICAL ENERGY

WHAT IS ELECTRICAL ENERGY?
It is a form of energy that is transported by an electrical current. It is very usually used because:
1-It can be easily transformed in other types of energy.
2-It can be transported over long distances in ways that are cheap and efficient.

ELECTRIC POWER STATIONS
A power station is a place where energy from natural resources is transformed into energy that we can consume. After the electricity has been generated, it can be transported to locations where energy is needed.

How electricity is generated
In electric power stations they use generators to transform energy into electricity. The electric generators used in power stations are called alternators.
An alternator usually has a stationary part, called stator, and a moving part, called a rotor.

THE TRANSPORTATION AND DISTRIBUTION OF ELECTRICITY
Electrical energy must be transported from power stations to the places where it is needed. The transportation of electrical energy includes:
-Raising the voltage: it is to avoid the loss of energy as heat
-High voltage lines: routes for high voltage lines are carefully planned
-Reducing the voltage: (they use substation transformers)
-Final: now, the power is distributed where it´s necessary.
