Oil, hydropower and wind power are all linked to solar energy
The chemical energy in oil is stored by ancient organisms and converted to solar energy
p>Hydroelectricity uses the potential energy of water, while nature's water cycle power comes from solar energy
Since sunlight forms the planetary wind system, wind energy is also converted from solar energy
Only raw materials for nuclear energy existed when the Earth was formed or was created by man .
The common advantage of solar power, wind power and tidal power is that they are renewable energy and can significantly reduce carbon emissions. greenhouse gases such as carbon. dioxide. The disadvantages of solar energy production are that its cost is too high, wind energy is too expensive,very limited by geography and that the use of tidal power generation imposes high requirements in terms of anti-seawater corrosion performance of electricity production equipment. Nuclear energy has remarkable advantages. The cost of nuclear power generation mainly concerns the infrastructure cost of nuclear power plants, which is approximately twice as high as that of conventional thermal power plants. However, uranium dioxide as a fuel is inexpensive and easy to transport. store. The energy density of nuclear fuel is millions of times higher than that of fossil fuels, so the fuel used in nuclear power plants is low. A 1,000 megawatt nuclear power plant requires only 30 tonnes of uranium fuel per year, which can be transported. by plane flight. The safety of nuclear power plants is extremelyhigh. The currently operating reactors will not cause radioactive material leakage accidents, at least technically, their safe operation can be fully guaranteed. Nuclear power plants can produce a large amount of thermal energy without producing dust, greenhouse gases, etc. like conventional power plants.
So far, no other energy source can replace nuclear energy, and other energy sources cannot match it in terms of economy and efficiency. The disadvantage of nuclear power generation is that there is no perfect and absolutely safe method for handling spent fuel.
