What is the difference between primary and secondary energy sources two
Primary energy can be further divided into two categories of renewable energy and non renewable energy. Renewable energy including solar energy, wind power, wind energy, biomass energy, wave energy, tidal energy, ocean thermal energy, etc.. They can be recycled in nature. Renewable energy, including: coal, crude oil, natural gas, oil shale, nuclear energy, etc., they can not be recycled, with a little, then a little less.
The primary energy obtained by processing the converted energy products, known as the two energy, such as electricity, steam, gas, gasoline, diesel oil, heavy oil, liquefied petroleum gas, ethanol, methane, hydrogen and coke etc..
An energy is taken directly from nature without a variety of energy and resources, processing including coal, crude oil, natural gas, oil shale, nuclear, solar, hydro, wind, wave energy, tidal energy, geothermal energy, biomass energy and ocean thermal energy and so on.
