There are several forms of energyWhat are they called? What is the use?
The primary energy is divided into renewable energy (hydro, wind and biomass) and non renewable energy sources (coal, petroleum, natural gas, oil shale, etc.). According to the production method can be divided into primary energy (natural energy) and two energy (artificial energy). Primary energy refers to the nature the natural form and without processing or conversion of energy resources, energy resources including a hydraulic renewable and non renewable coal, petroleum and natural gas resources, three kinds of energy including water, oil and gas, is the core of primary energy,
They become the basis of global energy; in addition, solar energy, wind energy, geothermal energy, ocean energy, biomass energy, nuclear energy and other renewable energy is also included in the scope of primary energy; two energy refers to the primary energy directly or indirectly into other types and forms of energy resources, for example electric power, gas, gasoline, diesel, coke, clean coal, gas and other energy laser and belong to two energy.
In accordance with the energy form can be classified into two primary energy and energy. The former refers to the nature of natural energy, existing energy, such as coal, petroleum, natural gas, water and so on. The latter refers to the secondary energy converted into energy products, such as electricity, gas, steam and various petroleum products
