People were optimizing for this here in Sweden, then a "peak effect charge" was introduced, where you're charged extra monthly based on the average of the three hours of largest effect usage. This is dialed in to be approximately 25% of the monthly bill at normal usage (and can go much higher).

TIL the cost of transporting energy around

Implementing long-distance high-voltage transmission lines is a common counterargument against the inherent fragile and unpredictable nature of variable renewable energy systems.

It's fairly frequent (several times per decade) to have high/low pressure systems with a radius of 100's of km, at which point a variable renewable system (wind+solar) can reach an output below <1% of installed capacity (when combined with the winter season) for extended (hours to several days) periods of time.

At that point, there is the choice of grid-scale long term energy storage up to a magnitude of TWh's (potentially seasonal), long-distance transmission (up to 1000's of km) or ensuring that other energy production systems exist that can pick up the slack (requiring redundant capacity, which is inefficient).

Thanks for putting the time and effort into keeping this running <3

It gets worse when you combine super LED brights with matrix headlights that are marketed to "allow the high beams to remain on even with oncoming traffic".

Makes sense. European capital markets have been operating at significant competitive disadvantage for decades now and many companies have been taken over by foreign ownership.

We have the same kinds of issues here in Sweden with Volvo Cars being Chinese since a few years back means that they're being phased out of any sensitive applications.
