I think nostr is the better decentralised social media technology, but I fear you might feel left out by the people that frequent it (as they would here).

The first, single folder for all of them.

I have a shared syncthing folder on all my devices

Syncthing is not limited to local network. It’s hole punching is one of the major features

Youtube channels. A simple timeline of uploads, only showing chanels I care about.

The cost of installation, wiring and transformers is more than the cost of panels.

After the 30 years of “borrowing” the panels, who pays for their removal and recycling?

In the context of this tweet most important differences are:

SQL is a language for querying databases.

Most common used databases are relational databases. With relational databases you can setup, well, relations and constraints.

Imagine you have 2 tables (2 excel sheets) one with people, and one with home ownership. You can set the following constraint: (1) each person shows up only once in the people table. And the following relation: (2) every home owner must refer to an existing person in people table.

When modifying the table contents, the system checks if no constraints or relations are violated.

Excel, just like a badly designed relational databse, would, for example, have no problem with duplicate people, or home ownership referring to non-existant people.

Or mongoDB 🙄

Probably something bespoke/legacy.

Cost for wind and battery back up

To supply germany for one week you need more than the world’s supply of batteries. It’s hard to speculate on the price of something that doesn’t exist.

Pumped storage is currently the only technology that could make grid-scale power storage work.

You’re incorrect in both your understanding of energy markets, and my paychecks.

but they allow windfall profits from renewables if they run

Again, you’re basing this on the day-ahead market. A marginal market in terms of traded power volume.

Due to how the pricing is regulated in the market there is a perverse incentive for electricity producers to keep expensive gas plants running

You’re probably talking about the day-ahead market (1). The price per kWh is indeed where bids and asks meet.

Only a small portion of electricity is traded on that market. It’s a marginal factor.

Most is traded OTC, longer term. There’s also the intraday-market. Finally, there’s the balancing price.

That is a naive way of looking at how the electricity market currently functions and is regulated.

I’ve worked as energy trader.

it highly disincentivizes producers to retire their remaining expensive gas plants and invest in better transmission and energy storage.

It is a fundamental problem of technology. Here in Belgium the government started subsidising gas plants, passing the costs on to end-consumers, as they’re necessary for balancing the grid, but unprofitable to run. (1)

As an analogy: it’s like buying a fleet of sailboats. As long as there’s a need for cargo to travel regardless of weather, you’ll still also be maintaining a fleet of motorized boats.

2nd source (Eurostat and European Environment Agency) corroborates the first: https://www.eea.europa.eu/en/analysis/indicators/greenhouse-gas-emission-intensity-of-1

10% of yearly electricity production in France comes from hydro (1)

Unreliable power generation needs on-demand backup generation, typically natural gas based. That’s the perverse effect of renewables: as grid scale seasonal storage is impossible, it increases dependence on gas. In Belgium we’ve even retrofitted jet engines to turbines as kerosine based emergency generation.

Now we’re paying for both the renewables and fossil infrastructure, both scaled to peak power usage. During dunkleflaute, you pay an arm and a leg. When unpredicted clouds or fog appear, you pay emergency balancing prices.

End result: Annualized price is high.

6th highest emissions per kWh of electricity produced in EU (1): 380g per kWh.

US: 370g per kWh.

France: 56g per kWh.

Sweden: 40g per kWh.
