What are the energy resource classifications?
Classified by their form, characteristics, or level of conversion and utilization. The World Energy Council promotes classifications: solid fuels, liquid fuels, gaseous fuels, hydropower, nuclear energy, electrical energy, solar energy, biomass, wind, ocean and geothermal energy.
According to the formation, it can be divided into primary energy or primary energy directly obtained from nature without changing its basic form, such as coal, oil, natural gas, solar energy, wind energy, hydro energy, biomass energy, geothermal energy, etc.; after natural or artificial The processing is converted into another form of secondary energy, such as electric energy, gasoline, diesel, alcohol, gas, hot water hydrogen energy, and the like.
According to whether it can be regenerated, it can be divided into renewable energy sources that can be continuously supplemented for use, such as wind energy; non-renewable energy sources that cannot be regenerated in a short period of time, such as coal and oil.
According to the degree of environmental impact, it can be divided into clean energy sources such as wind energy; polluting energy sources such as coal.
According to the utilization situation, it can be divided into conventional energy sources that have been mass-produced and widely used under existing economic and technological conditions, such as oil, natural gas, hydropower and nuclear fission energy; new energy sources currently being promoted, such as solar energy , ocean energy, geothermal energy, biomass energy, etc. Most of the new energy is natural and renewable and is the foundation of the world's long-lasting energy system.
