I remember being taught that price is a balancing factor - it moves to balance supply with demand. You can think of it as the pivot of a see-saw, with supply at one end of the see-saw and demand at the other; as supply or demand change price will always move one way or the other to ensure the see-saw stays horizontal. I'm no economist but the idea seems to capture market behaviour quite nicely.

I can't imagine that there has been a single hour since the electric generator was invented where no wind was blowing at all, not anywhere on the continent. That's what the grid is for.
I believe that Norway was very early establishing a nationwide grid, from the mid 1950s, completed in the early 1960. We were certainly not alone in moving electric energy from one region to another, but our net was perfectly phase synchronized from north to south, across a distance slightly larger than from Canada to Mexico. That is trivial today, with atomic clocks and all sorts of power semiconductors, but in the mid-1950s it was quite remarkable.
You simply have to prepare for a common grid that every electric power seller hooks up to, pouring their power into it, and the electricity peddlers tap out whatever they manage to sell, without caring about where the power is produced. The grid will take care of the transport task. The North European grid today covers the Scandinavian countries, the Baltic countries, Finland, Austria, Germany, France, Belgium, Netherlands and Poland. Should the wind calm down all over Northern Europe, the Norwegian hydropower stations would run at top speed. So would the Swedish nuclear plants (they always do!). When there is lots of wind, the hydropower is significantly reduced. Hydropower, as well as gas turbine generators, can easily and quickly be adjusted up and down, opposite of the availability of wind and solar power. Also note that although both wind and solar power depends on a nature we cannot control, statistics clearly show that when wind is at its plentiest, solar power is not. And vice versa.
I am not familiar with the power grid in the US, but I am sure there must be some way to transport significant amounts of power from one region to the other, depending on production and needs. Maybe free competition ideas causes more isolation, less cooperation, than in North Europe, so it may not work as smoothly as here, but I am sure that your lights won't go dark.

This strange idea of paying for electric energy ...
Tomorrow, for 22 out of 24 hours, we are being paid for using electric energy. The remaining two hours, it is free. Hopefully, this link is valid abroad as well: NordPool prices[^]. From 13:00 to 14:00, we are paid €2.99 per MWh consumed.
There is a snag to it, though. We are paid for consuming the energy. The power line company is not paying us for power line use; there is both a fixed (volume independent) fee, and a per kWh fee. So in total, there still is an expense. And there is a second snag: The "volume independent" part is not 100% so: It is affected by you peak hours - the average of your three highest peaks each month puts you is one of several brackets. If my hourly consumption for the peak hours exceed 5 kWh per wall clock hour, my fixed fee for this month jumps up by NOK 160 (roughly €15). So I should not, in joy over negative energy prices, crank up the heat, hot water tank, etc. etc. so that the 5 kWh/h line is crossed.
In the old days, "the power company" delivered both the energy and power lines. Politicians sold us the idea that forcing a split up by law would be a good divide and conquer strategy for the benefit of the consumers. In reality, it is a mechanism to make it simpler for the providers to manipulate energy and line prices independently, and in the name of "free competition" limit the consumers' freedom. E.g. in the old days, the student homes here in Trondheim were built as four small individual bedrooms sharing a kitchen, bath and electricity bill. Today, in the name of free competition, each bedroom must pay its own fixed fee, plus the consumed energy (mostly that is a LED table light and charging the smartphone). The fifth electricity bill, fixed fee for the kitchen/bathroom and the energy consumed for cooking and hot water, is split among the four students. The "logical" argument for this is that to be prepared for each student wishing to buy his energy from a different provider, they must have individual meters. The fixed fee is tied to the meter.
If I were a student today, I guess I would have started a major revolt against the power line company.

Same here in the UK (electricity, gas, water, railways), but most of these decisions were forced on us by the EU. And in reality they were a costly waste of time and money.

Considering the cost of manufacturing and then installing everything needed to get that "green power", who's the winner here?

There just was a huge protest rally in Germany against Tesla, who chopped down half a million CO2 absorbing trees, to make room for their new factory for building cars with less CO2 emissions.

The way I understand it is that energy suppliers pre book blocks of electricity months in advance. If they use it all, then they pay £X per unit. But if they don't use it, the price goes up because the actual energy generator has planned their usage and is pissed that it doesn't get used.
So it's cheaper for the supplier to offer free electricity in the hope that we will use the whole block (and maybe exceed their booking) to keep the price to them down.
Stupid system all round, which only exists so the middle men (suppliers) can make a (sometimes massive) profit.

That's crazy. But it must be profitable all 'round (except for consumers) if no one is crying for change (except consumers). Now I'm going to have to research how electricity is distributed here from the TVA to the local carriers, most of which are cooperatives or owned by municipalities. I assumed it was billed by actual usage, but after learning of your European schemes ... sheesh. All I know is they've never offered me free juice.

This company is the first that's offer me any either.
What really gets me annoyed is that they swear all my power is from renewable resources - but the price follows the oil and gas prices up (and occasionally down ...)

So y'all know... I'm getting my Zig on. And I come across videos about how slices are sooooooooo powerful, like Zig invented it. Basically, a slice just takes a subsection of an array with a pointer and a length. So you can focus on one part of it, in memory.
Now... all you C coders know exactly what I'm about to say here...
int main() {
int data[] = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9};
int *slice = &data[4];
*slice = 42;
printf("Bruh %d", data[4]);
return 0;
}
Don't get me wrong. Zig does have one nice abstraction in the fact it tracks the length for you for bounds checking. But still... come on. Gotta give props to C when talking about stuff when making it seem like this is something new.

My favorite optimization is Java substring which returns “slices” which reuse the source string’s char[].
If you have a big string in memory you can pull as many substrings as needed without ever copying a char.
Each substring has the storage overhead of a char* to the shared buff, offset, and length.

We had this in the proprietary language I started using in 1981. They were known as descriptors: each one contained a pointer and the number of elements, with the size of the elements determined at compile time. They could be created at run-time by specifying the first and last offset into an array.
