Electricity is an energy currency, rather than an energy source, which means that electrical generation needs to start from a primary energy source like a fuel or a primary energy flow. These fuels and flows are usually turned into electric current which transmits electric power to the grid.
An electric generator is a device that converts a form of energy into electricity. Most of world electricity generation is from generators that are based on scientist michael faraday’s discovery in 1831 that moving a magnet inside a coil of wire makes (induces) an electric current to flow in the wire.

The process of producing electric energy or the amount of electric energy produced by transforming other forms of energy into electrical energy; commonly expressed in kilowatt-hours (kwh) or megawatt-hours (mwh).
Electrical energy comes from renewable and nonrenewable sources; it is generally inexpensive and readily available, but it leaves many appliances and heating units defunct when power supplies are interrupted. The benefits and drawbacks of electrical energy depend primarily on its source.
Electric power, energy generated through the conversion of other forms of energy, such as mechanical, thermal, or chemical energy. Electric energy is unrivaled for many uses, as for lighting, computer operation, motive power, and entertainment applications.

Electrical energy is easy use and move from one location to another, but it is almost impossible to store in any large quantity. It can be used for running computers and most appliances, home heating, and even transportation.
Centralized generation requires transmission lines, which also use land. In addition to these environmental impacts, much of the primary energy (total energy content) of fossil fuels burned at power plants is wasted during generation and delivery to end-users.
