5. Non-renewable energy: Use a little less, mainly various fossil and nuclear fuels.
What is secondary energyndary?
1. Secondary energy: energy obtained after processing and conversion of primary energy, including electric energy, gasoline, diesel, liquefied petroleum gas and hydrogen energy, etc. There must be some degree of difference between secondary energy and primary energy losses.
2. Secondary energy can be divided into "processing energy" and "energy energy". Electric power is the most widely used processing energy, while gasoline and diesel are currently the most widely used energy.
