https://www.lepoint.fr/economie/l-eolie ... 520_28.phpToday, no large-scale and reliable storage system exists. For example, if we transform excess wind power into hydrogen and then return it to the electricity grid, we lose 70% of the energy in the process: it's prohibitive. There will undoubtedly be progress, but it will take time. However, the lifespan of a wind turbine is twenty years. The devices that we install today will therefore be outdated before we find a correct storage method.
On average, offshore wind turbines therefore produce electricity in France at a price twice that of onshore wind turbines, which is itself twice the market price! And I'm not talking about the disadvantages of offshore wind farms for fishermen, tourism or the seabed. What I just said concerns bottom-mounted wind turbines. Maybe the performance of floating wind turbines will be better, but we don't have any feedback yet.

Between the few Wh of your Chinese batteries and the few GWh needed for a wind farm, there is a big difference in scale.I regularly buy batteries (of different types) in China for my electric paramotor project! The price of stored Kwh has been halved in 2 years...and performance has improved!
https://www.energystream-wavestone.com/ ... s-isolees/We can ask ourselves if the model will be generalized since, if in the case of an island environment, the wind x stationary storage coupling is justified, it is relevant to ask the question for other environments. Indeed, the costs of these installations remain prohibitive most of the time and the environmental impact is not always positive due to the extraction of metals from the batteries as well as the difficulty of recycling them.
and nuclear power plants when paradoxically there is enough water in the rivers to cool down. So the nuk is not the solution either with global warming and the water problem which will become more and more recurrent.It's fashionable among politicians, but it's just to consume the energy lost by wind turbines, when paradoxically there is wind
the nuk is no better!Indeed, the costs of these installations remain prohibitive most of the time and the environmental impact is not always positive due to the extraction of metals from the batteries as well as the difficulty of recycling them.
