Extended data
Green electricity means that in the process of producing electricity, its carbon dioxide emission is zero or close to zero, because it has lower impact on the environment than electricity produced in other ways (such as thermal power generation). The main sources of green electricity are solar energy, wind energy, biomass energy and geothermal energy. In China, solar energy and wind energy are the main sources.
Clean energy, clean energy or green energy refers to energy that does not emit pollutants. The narrow definition is renewable energy, which refers to energy with renewable raw materials, such as hydropower, wind power, solar energy, biomass energy (biogas), geothermal energy, tidal energy, seawater temperature difference power generation and so on. At present, if the two are almost established, renewable energy has no possibility of energy exhaustion, so it is paid more and more attention by many countries, especially those with energy shortage.
It is worth noting that hydropower and solar energy are not green energy, because the process of building reservoirs and manufacturing solar panels will pollute or even destroy the environment. It should be carefully evaluated before use.
Nuclear power consumption of uranium fuel, uranium fuel is not renewable energy, high investment, almost all countries, including countries with the most advanced technology and management, can not guarantee the absolute safety of nuclear power plants (of course, no energy station is absolutely safe, and even reservoirs are in danger of dam failure). )
