The concept of primary energy is used in energy statistics in the compilation of energy balances, as well as in the field of energetics. In energetics, a primary energy source refers to the energy forms required by the energy sector to generate the supply of energy carriers used by human society.
We use renewable energy sources mainly to make. electricity. Electricity and hydrogen are different from the other energy sources because they. are secondary sources of energy. Secondary sources of energyâenergycarriersâ are used to store, move, and deliver energy in easily usable form. Wehave to use another energy source to make electricity or hydrogen.
