I was thinking of industrial-sized sites.
Tens of thousands of energy deposits with a power between 5kW and 50kW just waiting to be exploited for the energy autonomy of their operators
Good for them if they live near a good river.
and decentralized supply to the local network, i.e. without the considerable line losses resulting from the excessive centralization of the French network (it is estimated that 1kWh consumed at the outlet in France required 2,54kWh at the outlet of the power plant ) ...
Who is that? RTE announces 2.14% loss on its network in 201320m² on my roof produce 3000kWh per year, my electricity bill (household of 4 people) was 4000kWh (excluding gas heating). Between tiles that consume energy to make and do not produce and solar panels that will make 4 or 5 times the amount of energy consumed to make and recycle them during their life cycle, my choice is made ... Waiting better is useless since the prices inflated by subsidies are finally reasonable and at such low levelsRégsB wrote: For the PV, heuuuu, frankly, I would wait for better yields and efficient storage means before installing them on my roof, if I have one, one day.
It is true ! The financiers are gone and remain the industrialists who held the shock. As I am rather in the north, it seems to me for the moment still that thermal solar has the advantage.
thatin Spain, a "royal decree" prohibits individuals from making their own solar electricity because it is cheaper than electricity sold through the grid... The yield of the tiles is negative, I much prefer the 20m² of panels with the "meager yield" of 15% which gave me 12MWh (yes, MegaWatt hour) in 4 years than the tiles which cost me for their purchase and their maintenance without producing anything ...
This incompetence seems to be maintained,RégsB wrote: In total, around four times more production capacity, for actual production of the same order of magnitude. It is the price of the intermittence of the winds and the sun. And the target of 100% renewable energy has not been reached since this huge fleet of gas power plants remains.
Mhmmmm, I don't think the Frauenhofer Institute is incompetent!
but technological solutions exist and go through storage ... This will be the major challenge of the century that has just started.
Absolutely: storage will condition the success of intermittent RES, it is absolutely necessary to intensify research in the field.I just discovered this site which seems to emanate from anti-ecological lobbies.RégsB wrote: Or :

Yep, you also have to stop seeing conspiracy theories everywhere.When we point the finger at the fluctuating aspect of renewable energies, we must ALSO remember that consumption is fluctuating, even if this consumption is globally predictable.the imperative to stabilize the electricity network despite the massive and erratic influx of solar and wind power plants that produce energy unrelated to real needs, has pushed operators to their limits. Now, with a combined share of only 13% of total electricity production, the contribution of renewables is unreliable and massively jeopardizes the stability of the electricity network.
But consumption does not fluctuate at the same time as supply, hence the need for storage.
We must also admit the MAJOR handicap of nuclear energy which is very difficult and slow to modulate
This is not what is asked of it, nor, moreover, from the powerhouses.
and also requires the addition of energies that are easy to regulate, hydraulics is currently the most reactive energy with an instantaneous response time, unlike thermal power plants ...
Yes, it is absolutely essential to do without a thermal power plant!Nor will it be able to bear the additional cost of dismantling nuclear power plants ...RégsB wrote: I am indeed convinced that even Germany will not bear such an additional cost!
The cost of dismantling is 15 to 20% of the cost of manufacturing; we have already done in France, and the most difficult, and in the USA
As far as I'm concerned, I've been running on electricity for more than 120.000km, and I'm therefore trying to make my own energy transition, for more autonomy and economy ... But I am mocked and criticized by people who don't want to know or are afraid, like I was afraid 6 years ago ...
Now I go for it and railing all the time I have lost listening to others ...
What I have achieved with few skills (at the start) is achievable by many people, and I do not intend to stop, and even less to let say the nonsense that I read ...
As with electric mobility, the energy transition is an accessible grail which powerful lobbies do not want to see happen ...
I am absolutely convinced that an energy transition is essential quickly and is even inevitable!
But I refuse to be dictated by affect. You seem to have succeeded in your transition in a reasoned way, I admire those who succeed in this. You will still agree that your example cannot be extrapolated for the entity France. The needs are simply not the same.
