In France, we know very well how to vary nuclear power, in particular to adapt to the intermittency of renewable energies (which are very expensive for users).

According to a study by the International Renewable Energy Agency, wind and solar will soon become as competitive as gas and coal.

Fossil fuels cost between $ 5 and $ 17 per megawatt hour, the study notes, against $ 3 to $ 10 for renewable energies.
Fossil fuels cost between 5 and 17 dollars per megawatt hour, the study notes, against 3 to 10 dollars for renewable energies.
One step closer to the ecological transition for a greener future. According to a study published on Saturday, the costs of new energies such as solar or wind will fall so much in the coming years that they will soon be cheaper overall than fossil fuels. The International Renewable Energy Agency (Irena) also indicates in its study that other green energies are also growing rapidly.
"All renewable technologies will be competitive with fossil fuels in 2020," says Irena in this new study on the costs of green energies. Average costs of renewables should reach between 3 and 10 dollars per megawatt hour (MWh) depending on technologies (wind, solar, geothermal, biomass, etc.), when fossil fuels cost between 5 and 17 dollars per megawatt hour, note the study. They vary from country to country, according to energy deposits or regulations.
Already last year, the average costs of new projects for onshore wind farms and solar power plants fluctuated between 6 and 10 dollars per megawatt hour, with several records below this average. This was the case in the United Arab Emirates, Chile, Mexico and Peru in the solar sector. In wind power, projects are already regularly commissioned at a cost of $ 4 per megawatt hour.
More competition
The cost reductions are driven by the constant improvement of technologies but also by increasing competition with many companies that develop renewable energy projects, notes the study. "Turning to renewables (...) is no longer simply a decision made in the name of the environment, but, more and more widely, an intelligent economic decision", according to Adnan Z. Amin, managing director of l 'Irena, quoted in the press release.
The “best” onshore and solar wind projects could generate electricity at a cost of $ 3 per megawatt hour, or even less in the next two years. And this drop in costs is also observed for other renewable energies, notes Irena. Last year, projects in geothermal energy, biomass or hydroelectricity developed with costs around $ 7 per megawatt hour. Concentrated solar and offshore wind are also making progress and some projects that will be commissioned by 2020 and 2022 will cost between 6 and 10 dollars per megawatt hour, predicts Irena. "This new dynamic shows a significant change in the energy model", according to Adnan Z. Amin.
This for the cost only!
An old saying goes that "
Paris was not built in a day"and ecology, renewable energies such as solar and wind power (which are not the only renewable energies) are still in their infancy. And for those with short memories, we must remember blunders nuclear which could only be established because France wanted its nuclear bomb at all costs and these plants had as main reason for being to manufacture fuel for this purpose. that a way to valorize the waste of the enormous thermal production (which would have boiled the rivers) and thus to justify what was hidden behind.
The only valid argument is that of intermittence due to wind and sun, obviously periodic.
The Hydroeolian can overcome this intermittence because the wind is permanent at sea, perhaps too much for pure wind. (We are still waiting for the first hydroeolians on our coasts!)
As for the photovoltaic photo, it is unfortunately extremely polluting in its manufacture and its reprocessing, currently, less despite everything than nuclear fuels which we still do not know how to avoid the risk of accidents for THOUSANDS of years to come and that at an enormous cost, there!
