Information about Primary Energy
Primary energy is energy that has not been subjected to any conversion or transformation process.
Primary energy is energy contained in raw fuels and any other forms of energy received by a system as input to the system. The concept is used especially in energy statistics in the course of compilation of energy balances.
Primary energy includes resource energy and renewable energy.

Conversion to secondary energy
Primary energies are transformed in energy conversion processes to more convenient forms of energy, such as electrical energy and cleaner fuels. In energy statistics these forms are called secondary energy.See also
Fuel is any material that is burnt or altered in order to obtain energy.[1] Fuel releases its energy either through chemical means, such as combustion, or nuclear means, such as nuclear fission or nuclear fusion.

Resource energy or non-renewable energy is a the energy taken from a source which is depleted by extraction. It rely on consumable materials. Non-renewable energy sources come from the earth and appear as either solids, liquids, and gases.
