Is nuclear power the most promising or declining energy
"the relative price of power generation has changed. In most countries, solar energy and wind energy are now the most convenient. This information often uses 1000 (5) 000n tensile test opportunistic combined energy."
this sentence sounds like a draft to promote renewable energy, or propaganda from environmental protection organizations, but in fact it is one of the main conclusions of the 2018 version of the "state of the nuclear industry report" (wnisr)
the report is published annually, based on the views of third parties, and aims to openly discuss the sustainable development of nuclear energy and reasonable thinking methods of the nuclear industry
the report shows that the nuclear capacity increased by only 1% in 2017, while the share of wind energy and solar energy increased by 17% and 35% respectively. The share of nuclear power in global electricity production has fallen sharply from 17.5% in 1996 to 10.3% in 2017. In 2017, the total investment in nuclear power was only US $16billion, while the global investment in wind energy and solar energy was US $100billion and US $160billion respectively. Investment in new nuclear power plants is mainly driven by public support and nuclear weapon states, rather than private sector support; If it cannot be proved that commercial, small, factory assembled modular reactors with reliable passive safety functions can be developed at a lower cost, nuclear power will have little competition in the future. Most importantly, if it fails to attract private investors, its prospects seem remote
the accuracy is ± 1% of the starting indication of 20% of each range. The document also states that some countries support nuclear power projects, which often facilitates the conduct of batch experiments; Rent and corruption. Especially because of their large scale (1 GW to 1.6 GW), nuclear power facilities are considered to be an infeasible solution for many African developing countries. Their power systems are usually small and unable to integrate large capacity
according to the report, only four reactors were put into operation in 2017, including three in China and one in Pakistan, while five other nuclear power plants around the world are under construction. In addition, the number of reactors under construction decreased from 68 at the end of 2013 to 50 in 15 countries by mid-2018, 16 of which are in China. China's nuclear power increased by 18% in 2017, and its share in the country's power structure increased from 3.6% in 2016 to 3.9% last year
as of the middle of 2018, 115 nuclear power plants are being decommissioned, but so far, only 19 units have been completely decommissioned: 13 in the United States, 5 in Germany and 1 in Japan
experts say that what really impacts nuclear power is economic benefits. According to the report, "The electricity auction has led to record lows in the prices of onshore wind power (US $20/MWh), offshore wind power (US $45/MWh) and solar power (US $25/MWh), while the implementation price of a nuclear power project of Hinkley point C project (US $120/MWh) 。
although heating is considered a secondary issue, the report highlights the impact of nuclear power on global warming. Because nuclear reactor cooling requires a lot of water, which makes the water flow warm and accelerates global temperature change. Governments, especially in Europe, are imposing operational restrictions to avoid excessive River heating. To alleviate the problem, some reactors have been shut down, including at least four in France
value in recent years, vehicle lightweight has become an effective measure to reduce vehicle emissions and improve combustion efficiency. It should be noted that the French government has clearly stated that it will reduce the share of nuclear power from about 71% at present to 50% in 2025. EDF, a French power giant, has announced its intention to sell non core assets worth $11.4 billion. The project was finally approved in September 2016. At the same time, EDF announced a 30 gigawatt solar energy plan to offset the losses of nuclear power
