Electricity is a secondary source of energy because we get electrical energy by converting primary sources of energy, like, natural gas, nuclear energy, solar energy, and wind energy into electric powerElectricity is referred to as an energy carrier, which means it can be converted to other forms, such as mechanical energy of the turbine is converted into electricity or heat energy to rotate the turbine for generating electricity. However, electricity is neither renewable nor non-renewable. Therefore, electricity is a secondary source of energy though it cannot be classified into renewable or non-renewable sources of energy.
