Primary energy: energy resources that exist in nature in their original form and have not been processed or converted. Also called natural energy, including fossil fuels (such as raw coal, crude oil, natural gas, etc.), nuclear. fuel, biomass energy, hydro energy, wind energy, solar energy, geothermal energy, ocean energy, tidal energy, etc.
Secondary energy: Secondary energy refers to the energy obtained after processing and conversion of primary energy, such as: electricity, steam, gas, gasoline, diesel, heavy fuel oil, liquefied petroleum gas, alcohol, biogas, hydrogen and coke, etc.
Renewable energy: hydropower, wind power, solar power, geothermal power, bioenergy, tidal power
Once Energy includes: raw coal, crude oil, natural gas, nuclear power, energy solar,hydropower, wind energy, wave energy, tidal energy, geothermal energy, biomass energy. and the energy of the ocean temperature difference, etc.
Secondary energy includes: electricity, steam, gas, gasoline, diesel, heavy fuel oil, liquefied petroleum gas, alcohol, biogas, hydrogen and coke, etc.
Primary energy can be divided into two categories: renewable energy and non-renewable energy. Renewable energy includes solar energy, hydropower, wind energy, biomass energy, wave energy, tidal energy, ocean temperature difference energy, etc. They can be recycled into nature, while non-renewable energy sources include: coal, crude oil, natural gas, oil shale, nuclear energy, etc. The more they are used, the less they will be.
EnergyPrimary energy, also known as natural energy, refers to energy obtained from nature and used directly without modification or transformation. Such as raw coal, crude oil, natural gas, hydroelectric power, wind power, solar power, ocean power, tidal power, geothermal power, natural uranium ore , etc. Primary energy is divided into renewable energy and non-renewable energy. The first refers to natural energy that can be produced repeatedly, including solar energy, wind energy, tidal energy, geothermal energy, etc. ; various fossil fuels and nuclear fuels.
Primary energy refers to energy extracted from nature and used directly. This is the energy contained in natural resources (such as coal, crude oil, sunlight, uranium, etc.) that has not been transformedmated or converted by man. .
Secondary energy refers to the energy obtained after processing and conversion of primary energy, including electric energy, gasoline, diesel, liquefied petroleum gas, energy hydrogen, etc. Secondary energy can be divided into "processing energy" and "energy energy". Electric energy is the most widely used processing energy, while gasoline and diesel are currently the most widely used energy energy.
Secondary energy can also be explained as energy that is reused in primary energy. For example, burning coal to produce steam can power a generator, and the electricity produced can be called secondary energy.
Secondary energy is different from primary energy. It does not come directly from nature and can only be obtained by processing and converting primary energy. By conséWhat, strictly speaking, is not an “energy” but should be called “primary energy”. secondary energy. "capable". The energy crisis, renewable energies, etc. do not involve secondary energy.
