@EnergySRE Or like if 400 of the cars in NYC were EVs doing flex services..

@JerryTurin @tchbstrd @Noahpinion Wikipedia says it was developed by Bytedance in China, originally released only there under a different name, and then taken international by the same firm under the TikTok name?

@cindylouwhotrue @JohnSmillie42 @caelan_saunders What alternative path for energy should nations take in your view?

@LewisJEllis @kellabyte omfg this thing just keeps.. it's just christmas presents containing other christmas presents

@jgkoomey Looks like it’s on a retaining wall? Probably best not to lean too hard on it..

[Jacob Davis-Hansson @jakewins]

@jgkoomey Fixed survey target, like this: https://t.co/VmB951uOF1

I guess letting them track how much whatever it’s attached to moves over time, relative to some other spot?

@NatBullard @janrosenow They don’t have Q4 yet tho, but they will add it. You can see Q1-Q32022 in the table below (on mobile at least) the main chart

@jimwebber There are like 30M cars in the UK; in 15 years the majority of them contain, say, a 50kWh battery.

30M * 50kWh makes a big distributed battery!

[Jacob Davis-Hansson @jakewins]

@jimwebber Smart meters is why our whole portfolio peaks during cheapest energy hours, from our customers smart-charging their EVs in the cheapest time slots.

Customers pay significantly (50-75%) less to charge EVs, and shape grid load so it follows cheap intermittent renewables.

@tagir_valeev Watching the “here’s how it’s done proper” - indexing into lookup tables after rounding with no bounds checks, loops allocating on every iteration…

Vs original that is so utterly clearly correct, has no logic for the reader to mentally execute, no allocations..

@mdavidallen @EastlondonDev @Tailscale @NotionHQ Backstage is kind of that, like.. Wordpress or Django for company portals, tons of off-the-shelf plugins, trivially extensible.

Though it’s very development focused, eg things like “directory of services, their API docs and dashboards”

[Jacob Davis-Hansson @jakewins]

@EastlondonDev @mdavidallen @Tailscale Do you mean actual network intranet, @mdavidallen, or like wiki-esque things?

If the former, +1 on @Tailscale, they are bringing back corporate networks! If the latter, we use @NotionHQ (mixed experience) and Spotifys Backstage (fan)

@duncancampbell Like if you boil some water and then measure the energy delivered by the stove into the pot while it’s boiling, that would
Make the stove seem super efficient, but it’s just maintaining an equilibrium at that point

[Jacob Davis-Hansson @jakewins]

@duncancampbell Guessing, know nothing about fusion: Is there maybe a ton of accumulated heat delivered by the laser “ahead” of the output measurement time window?

[Jacob Davis-Hansson @jakewins]

@EricMCornelius @Noahpinion Then why do the cost optimising papers not say to build more nukes?

You said because they don’t consider storage costs.

Can you show an example of a paper that does whole-energy-system least-cost-path optimization that does not include “build tons of PV+Wind” in solver output?

[Jacob Davis-Hansson @jakewins]

@nuclearzak @xiaowang1984 @Noahpinion Yes, exactly this. RE enables rapid reduction in burning and shipping of fossil fuels.

We then need dispatchable power to meet the gap given by max(demand - all wind in grid - all solar in grid - demand flexibility )

[Jacob Davis-Hansson @jakewins]

@EricMCornelius @Noahpinion Oh “gen capacity”+”first chart”: Yes that is true, but how is that relevant here, discussion was energy not power.

The discussion was: people say pv+wind cannot replace dispatchables, yet less energy is generated by them, more from PV+wind, so they clearly *are* replacing

[Jacob Davis-Hansson @jakewins]

@EricMCornelius @Noahpinion The Y axis is in billion kWh? That's aggregate total volume produced, or am I having a stroke?
