Nachzahlung für #Strom bei Endabrechnung von 04/22-04/23, also quasi die Hochpreisphase. Gut 600€. Ich hatte zwischenzeitlich schon den Abschlag angehoben, aber ganz gereicht hats nicht.

Da könnte man jetzt anfangen zu jammern. Das ist aber unser Strom- UND Heizungsbezug(!!).

Aber WP und eAuto ist ja alles Ökospinnerei und lohnt sich kaum. *ironie off

Wie hoch mögen die Abrechnungen bei ggf. unsanierten Fossilien gewesen sein oder werden? :/

On July 14, I wrote that we had broken even on power, we had consumed as much electricity as we had produced this year. The surplus we built up during the rest of the summer is now gone. We broke even again at 8.41 MWh.

At the end of the year, we'll have a deficit of ~1 MWh which I think is great since it's a 220m2 house with everything on electricity.

Giant batteries that ensure stable power supply by offsetting intermittent renewable supplies are becoming cheap enough to make developers abandon scores of projects for gas-fired generation world-wide.

The long-term economics of gas-fired plants, used in Europe and some parts of the United States primarily to compensate for the intermittent nature of wind and solar power, are changing quickly, according to Reuters' interviews with more than a dozen power plant developers, project finance bankers, analysts and consultants.

Interestingly, when looking at which #renewableenergy source to prioritise governments might be well advised to (for the moment at least) to pivot towards #solar.

It looks like both the ease of manufacture of components & the current post-Covid glut in the #supplychain are driving down the prices of solar components, while the more complex mechanical needs of #windpower are keeping prices high(er).

So a pragmatic policy right now would be to focus on ramping up solar energy...

I think there's a message in it for Australia. Like Portugal, we're nuclear-free. Hydro will be a challenge, we don't exactly have a lot of dams suitable for that, but we should be putting solar on every roof we can, setting up wind farms and improving our battery storage.

This is really neat. We should really be putting solar over any and every artificial water body at least, especially ones that aren't home to wildlife like canals, reservoirs, etc.

I have to think it's worth it on aquaculture bodies as well. I wonder whether and how much they'd benefit from keeping the water temperature cooler through shading as well.

I appreciated this Foreign Policy article that talks about how the green transition will mean LESS mining, not more.

Flooded mines across the UK could store large amounts of wind energy that would otherwise go to waste by heating up the water within them. The heat could then be extracted to warm homes in winter.

It suffers from the same fundamental problem as vertical axis wind turbines. At some point, the blades are travelling into the wind. That's not good for efficiency.

It looks too simple.

$0.013/kWh wind energy from simple mass manufacturable parts that can be transported easily and constructed with well known techniques.

It seems like it would require a lot of land. But my estimate is that it's about the same as we currently use for coal power in Victoria (mines, powerplants and cooling ponds)

“Energy Vault claims its technology, based around ‘storage towers’ of custom-designed bricks, replicates the gravity-based approach of large-scale pumped-hydro storage, but at lower cost and without the need for water or particular topographies. Instead of water, the huge bricks are hauled upwards by crane to store energy and released for discharge, controlled by custom-designed software.”

Wind tubines:

1. Kill whales.

Bullshit. Constantly referring to results published nowhere from a study that never took place remains bullshit.

2. Reduce ocean swells, killing surfing.

Bullshit. You would have to build a literal wall of turbine towers to stop ocean swell, which developes over hundreds of kilometres. The best surf involves ocean swell and offshore winds, which simply can't be affected by offshore wind turbines.

3. Reduce onshore winds by 40%.

Bullshit. There is no indication that wind turbines reduce onshore winds. The wind continues past the turbine blades, they don't block it; they don't even slow it down by any reasonable measure. A couple of hundred metres past the turbine you can't measure any effect at all.

4. Reduce fishing catches.

Bullshit. The tower bases, buried in the ocean bed, provide safe places for fish nurseries and coral growth, increasing the local fish population.

Don't buy into the disinformation being spread in order to stop offshore wind turbine installations. Look at who benefits from them not going ahead.

Projects hijacked by ‘political actors like Peter Dutton suddenly pretending to care about whales’.

Associate professor Michelle Voyer was startled to see an article from the internationally esteemed academic journal Marine Policy asserting that wind energy projects proposed for the waters off the Illawarra and Hunter Valley would kill 400 whales a year pop up on social media.

After all Voyer lives in the Illawarra, and due to her role as principal fellow with the Australian National Centre for Ocean Resources and Security at the University of Wollongong, she has expertise in the field. She is also, it turns out, associate editor of Marine Policy. She did not recognise the article.
