Cool chart, turns out that “when the sun doesn’t shine” not so important already in California

Cool graphic of California elec supply (and storage charging) over 24-hour periods. Solar supplies majority during daylight but storage then provides a sizeable chunk for first few hours of evening.

Chris Adams @mrchrisadams.bsky.social · 2d

Wow, Kate, that's quite the chart - I knew batteries were growing fast in Cali, but I hadn't seen it laid out so clearlty before - where is this from?

I'd love to reference it in a talk in future, as normally these charts can look pretty intimidating to ppl new to thinking about energy systems.

Only a couple more months for humans to invent the massive kaiju-fighting robots of Pacific Rim, which takes place in 2025. My optimism is waning.

If you rename the Department of Defense the Department of War, then bomb fishing boats in the Caribbean, and shoot an unarmed priest in the head with a pepper bullet, you should automatically be barred from receiving the Nobel Peace Prize for the rest of your life.

The US is pursuing "energy dominance" and forcing allies to buy US oil and gas. And, yet, China is beating the US on energy exports.

Ah, thanks Jan - this is v helpful.

After a bit of reading, I get the general idea that doing this with the web platform in a PWA would be quite difficult. Every approach I can think of (I didn't spend long, to be fair), would require the centralised database or would monster battery.

Sad times :(

Chris Adams @mrchrisadams.bsky.social · 12d

I’ve never used this. I’m a British person living in Germany. Is there a write up online of the specific features that make it impossible (or at least very difficult) to use as a PWA? It feels like it would be a good example why you might favour the web platform for projects like this if so.

This is amazing: @ladwp.com, the Los Angeles utility, has launched a program that will install solar+battery systems on qualifying low-to-moderate-income households, *for free*.

Yes: free.

⚠️ Chinese researchers have invented bone glue that mimics how oysters stick to surfaces underwater.

The adhesive can reportedly repair orthopedic fractures in 2-3 minutes, even in blood-rich environments, and is bioabsorbable.

People signing the petition against the increase in parking charges in hammersmith and Fulham are signing a petition for the more than half of borough residents who do not own a car to subsidise the wealthier minority who do own a car to store it in the street. Don't believe me?
Ask yourself:
- Do people believe highways maintenance and parking management is magically free for the council?
- If not, how do they think it should be paid for?
- Out of council taxes, which we all pay, whether or not we own cars?
- Or is that people think all of these costs should somehow be recovered from drivers who live somewhere else other than Hammersmith and Fulham?
- Local authority revenue from parking can *only be spent on local transport costs*; maybe the people signing this petition would like to see much less spending on road maintenance in the borough? Less street sweeping, clearing up fly tipping, mending broken pavements and filling potholes?
It's all very unedifying to watch honestly and I hope you, dear reader, are not someone who believes you have a god given right to park your private property in the public realm in our crowded city, and that it is someone else's responsibility to foot the bill for making this possible.

That quote is from this piece:

www.cleanenergywire.org/news/german-...

It suggests otherwise.

If permitting batteries is easier? It should be, but I don't know if it is.

They seem like they would that be the most likely new dispatchable generation capacity we might see come online now, right?

Chris Adams @mrchrisadams.bsky.social · 19d

Then there's the whole issue of permitting too though:

"Holger Kreetz, chief operating officer (COO) at energy company Uniper, said that permitting and construction would take at least five years after the auction until a new plant starts feeding into the grid"

So that's like... 2030? 2031?

First there's the whole global turbine shortage in effect - I assumed Siemens might do a favour the german gov, but this quote suggests not:

“The tender for the 20 GW is supposed to happen quickly, but turbine manufacturers currently do not have 50 turbines in stock waiting to be picked up,”

Dear #energysky - I have a query about Germany's plans to build 20GW of gas turbine capacity in the coming years as described here.

www.cleanenergywire.org/news/germany...

Is it really plausible we'll see new gas on the main German grid before 2030?

Here's fig 5, showing the estimated costs for a 100% hourly matched carbon free portfolio for Germany and Poland respectively.

The Y-axis on chart doesn't even go beyond 130 EUR, and the cost increase is pretty gradual.

(there's much more to the topic, obvs, but for today, this made my day)

Chris Adams @mrchrisadams.bsky.social · 21d

My assumptions for hitting 100% fossil free (or carbon free if you prefer Google's terminology) power totally need to be updated after reading this paper. I assumed it would be really really expensive to decarbonise power in Germany as in hundreds of EUR per MWh for the last percent to reach 100%
