More condescension... any renewable kWh with little CO2 is good to take!

You are not aware of technological developments and the fall in the price of kWh that can be stored in batteries...There are however a lot of subjects on this on the forum...

So much contempt and you cry that the sea ice is melting?

It's just anecdotal, don't tell salads...

In reality
Today, 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 The devices that we install today will therefore be outdated before we find a correct storage method.
https://www.lepoint.fr/economie/l-eolie ... 520_28.php

On the contrary, wind power is sold at a negative price when there is wind.
No better for offshore wind
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.

Germany, which has thrown itself fully into wind power, is forced to depend on Russian gas to compensate for the intermittency : roll:

The means of storage and production of alternative energy to nuclear exist, but not the political will of a world plagued by money. You've been here for eight years and you refuse this reality. How does it feel to live a lie all the time?

The objective is to produce as low-carbon and competitive as possible and we are far from it with the "alternative" : roll:

Blablabla...why are you talking about hydrogen?

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!

If here it does not fall in Europe it is simply that big pigs get greased! As they did with the PV... : Lol:

So no, it's not anecdotal!

You're clogged with emery, well no, you're well aware of it since you skip the main point: it's a POLITICAL problem.
Money in the background...

How does it feel to live a lie? It gnaws?

Yes, deciding to subsidize a little, a lot, madly or not at all any sector that is not competitive at a given moment in the electricity market is indeed a political decision. This explains why subsidy schemes and deployment objectives vary from country to country depending on their specific situation.
So what?

It's fashionable among politicians, but it's just to consume the energy lost by wind turbines, when paradoxically there is wind
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!
Between the few Wh of your Chinese batteries and the few GWh needed for a wind farm, there is a big difference in scale. : roll:

There are projects that work for small islands but it is not ready to generalize
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.

It's fashionable among politicians, but it's just to consume the energy lost by wind turbines, when paradoxically there is wind
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.
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.
the nuk is no better!
