Same. It being on a board like eli5 makes it even more spammy.

Sadly, others have argued so and still are. Here in Belgium the Green party is still trying to close existing, running nuclear power generation. In favour of building new subsidised "emergency" gas generation 🙄

Until then grid battery storage can mature and demand adjustment projects can be rolled out.

In my experience, people tend to severily under estimate the size of the storage problem. To power germany for a week it takes about 7TWh. There's around 0.1TWh of storage installed in the whole of Europe.

As far as I know, the power outage in Portugal and Spain did not start with renewables

Grids are best modelled as a system, jointly operating. Insufficient damping is the cause as per the grid operator (1).

Can be solved in multiple ways such as make it a france problem (stronger interconnects to a system with more turbines), storage, improved DC-AC transformers for small (<1MW) solar plants. (*)

Pumped storage is indeed one of the best known technologies for grid stability, as it provides both storage, and turbines with inertia. Hard to build though, finding funding and appropriate locations. Then solar suddenly isn't as cheap if one takes into accou t the cost to make it a reliable source of energy.

(*) the report mentions an estimated 700MW of production auto-shutting down as grid frequency dropped. Most likely these are the inverters of small scale solar installations, which are frequency following (measure then adjust) rather than synchronizing, and simply shut off when out of bound. To quote:

The rapid schedule changes in photovoltaic generation driven by price fluctuations in electricity markets. From an electrical standpoint, such abrupt changes in inverter - based generation introduce significant imbalances into the system, because regulation mechanisms haven´t operated yet. These imbalances must be compensated mainly through interconnections, particularly the one with France . Severe imbalances lead to drastic shifts in power flows across the network, which in turn alter the capacitive and inductive behaviour of the grid. Consequently, system voltages can vary rapidly. This effect is further exacerbated when such generation oper ates under power factor control and doesn´t provide dynamic voltage control, as it limits the dynamic reactive power support that could otherwise help stabilise voltage

The worlds production of storage isn't even sufficient to power germany for a week. Hence why germany is heavily dependent on gas. Mostly US liquified natural gas, and russian pipeline gas.

To me, it's a surprising statement that, for the same amount of money, one can buy something that doesn't exist. 🤔

In terms of engineering, it takes renewables + shitload of storage in order to have equivalent power generation characteristics to nuclear.

The recent portugal/spain power outage was due to the system being insufficiently damped (insufficient storage/inertia to buffer (the loss of) a high proportion of unpredictable power generation).

I find that digitalocean (which is a VPS provider) has great tutorials.

I often tend to search "how to X site:digitalocean.com", despite hosting almost everything on my own hardware.

That’s what scares me - not being wrong, but being convinced I’m right for reasons that are more about mood than method.

I think that'll be the case most of the time. The only known way to get a grasp of reality is cooperation, and the agreement to let experiment be the arbiter of truth. Which is difficult, as many systems can't easily be experimented on in isolation (and you're left with counterfactuals only).

Histories greatest thinkers struggled with this too. Descartes changed his famous postulate "je pense donc je suis" to "je doute donc je suis" later in life. ("I think therefore I am", became "I doubt therefore I am"). I read that as trading reason for emotion as core to his being.

If me and 5 friends read your a-hole, I bet all of us would come to the same conclusion.

Are you a dog or cat person

Yeeeeezs you know what you want

Do you have a go to tim hortons' order?
