Begründung, dass Windräder negativ für Elche sein sollen würde mich interessieren.
In Finnland ziehen die Windräder die Elche eher an. Der Elche wegen sollten sie also erst recht Windräder bauen.

Outo ilmiö kummastuttaa metsästäjiä: Miksi tuulimylly houkuttelee uroshirviä?
Hirvien erikoinen käytös kummastuttaa metsästysporukoita. Havaintojen mukaan hirvet ovat alkaneet kerääntyä tuulivoimaloiden läheisyyteen, sen sijaan että pelkäisivät niitä.
Spekulaatiota on käyty si...

🔹 The rate of expansion of renewable energies strongly influences the necessary hydrogen import volumes
🔹 Hydrogen storage is essential for the success of the energy transition.
🔹 The European Hydrogen Backbone can handle the supply task.

🔹Industry is the main driver of hydrogen demand.
🔹Largest customers: chemical industry, iron and steel production and high-temperature process heat (glass, cement, lime)
🔹 Demand will not increase significantly until 2035.

Yep there is quite good data from VTT for several A2A heat pumps. Quite some differences for different models.

Unfortunately down to "only" around -30°C.
For A2W I am not aware of similar data.

Here is the original chart with the numbers from @rautiainen on X.
Strong demand reduction (1) at high DA prices (2) can be seen even though temperature (4) is low.

But including demand flex in the bids would have probably reduced DA prices. This time underestimating demand flex lead to too high DA prices.
Demand flex creates quite some challenges for retailers, so they will need improve their demand forecasting. Certainly a challenge!

The aggregated curves shows the tight and steep situation on the day-ahead market and how much lower prices would have been hypothetically with actual demand.
Obviously the question remains, whether a price signal of 150 €/MWh would have caused this big demand flex.

The challenge to forecast that day's demand is shown by the TSO's forecast vs. the actual demand. Deviations of up to 1,4 GW = 10% of total load.
Previous data was missing as prices and temps set records. (And TSO Forecast is calculated before DA auction)

For electricity retailers this situation caused problems. They overestimated their (dynamic) customers' demand and bought too much electricity on DA market at a high price (chart 2) and had to sell it at low values on the ID markets.

Da haben dann relativ kleine Kraftwerkausfälle große Preiskonsequenzen bei so knapper Situation.
Morgen darf kein AKW oder keine größere Übertragungsleitung ausfallen.

Die Kraftwerkausfälle tragen zur Situation bei, aber ursächlich ist primär die hohe Nachfrage aufgrund Temperaturen um die -30 Grad im Großteil des Landes.

Demand is high due to the cold weather and quite a few fossil power plants are having outages and making supply tight.

Mit Schuko lässt es sich mit etwas Geduld ohne Probleme laden.
Wenn wir aber skalieren und BEV „systemdienlich“ flexibel laden wollen, brauchen wir höhere Ladeleistungen, um
Freiheitsgrade für gesteuertes Laden zu schaffen.
Sollte am Ende Geldbeutel
und Umwelt freuen.

Will the emission accounting with GREET include upstream emissions of renewable energy? Would have quite an impact on the level of tax credit received.
RED II DA neglects those upstream emissions.
0 kg/kg or 2.2 kg/kg makes a huge difference in the IRA. www.ffe.de/wp-content/u...

Maybe we should simply accept that comparing LCOE of current electricity generation types is not possible or useful.
There is a reason why we use complex energy system models instead of planning the energy system model with annual duration curves or LCOE.

Danke. Wäre spannend zu wissen wie diese Abschätzung stattfindet. Gerade mit sich verbreitenden Heimspeichern zunehmend eine Herausforderung würde ich vermuten.
