(1) 1 natural gas: 3 wind energy; 4 hydraulic power; 5 petroleum energy; 8 geothermal energy; 10 solar energy; 12 gas pipeline energy; energy belongs to once Energy;
2 Hydrogen; 7 Electrical energy; 12 Piped gas;
(2) Among them, non-renewable energy sources include 1 Natural gas; ; 5 Oil; 6 Coal; 10 nuclear energy, 2 hydrogen; 3 hydraulic energy; 7 tidal energy; 9 solar energy; /p>
(3 ) Among them, the conventional energy sources are: 1 natural gas; water energy; 5 coal; 12 chemical energy; 2 hydrogen; 3 wind energy, 8 tidal energy; 9 geothermal energy; 10 solar energy; 14 biomass energy
(4) Among them, 2 hydrogen; ; 7 electrical energy; 8 tidal energy; 9 geothermal energy; 11 solar energy; 13 chemical energy.
So the answer is: (1) 1, 3, 4, 5, 6, 8, 9, 10, 11, 13, 14;
(2) 1, 5, 6, 10; 2, 3, 4, 7, 8, 9, 11, 12, 13, 14
(3) 1, 4, 5, 6, 7; , 12, 13; 2, 3, 8, 9, 10, 11, 14
(4) 2, 3, 4, 7, 8, 9, 11, 13; 10,12,14．
Energy can be divided into primary energy and secondary energy, or renewable energy and non-renewable energy. The following five energy sources: wood, coal, solar energy, oil,
| Inside the sun, hydrogen nuclei undergo nuclear fusion at ultra-high temperatures, releasing huge amounts of nuclear energy. It is solar energy, so solar energy is not a fossil energy or a secondary energy, but a primary energy obtained directly from nature and is a renewable energy. Then choose D. |
(1) The energy which is to be obtained through primary energy consumption is called secondary energy. Of the four types of energy, only electrical energy requires it.consumption of other forms of energy. It can be converted into electrical energy, so electrical energy belongs to secondary energy.
(2) Energy that can be supplied for a long time or can be renewable is a renewable energy source, so firewood and solar energy are energy sources renewable.
So the answer is: electrical energy; firewood, solar energy.
