There has been a long standing request to split Germany into multiple price zones[1], because Germany as a single zone does not adequately match the underlying network transmission limitations and there have been multiple occasions where power flowed through neighboring zones, which in turn required both network upgrades[2] in the zones neighboring Germany and expensive redispatch[3] in the south Germany. Industry in the south of Germany fights this back as this would mean the energy prices in the south would rise (and drop in the north), as when the transmission lines are congested, the prices start to diverge.
Keeping Germany a single zone is essentially a subsidy to Bavarian industry. The industry fights this so hard that it has basically become an energy insider joke.
They could also just split the Germany into multiple bidding zones, then north parts of Germany would have a lot of cheap wind power, similar as in Sweden.
No, these are two different things. One is stability market, where batteries are now king, the other is physics of fault ride-through, where actual physical inertia is a real neccessity, at least for the time being. That is why synchronous condensers are installed.
Every major renewable grid has installed additional intertia to avoid blackouts.
Ha, yes, a lot of deniers/delayers are going on about how Germany "wasted" billion on renewables, when in fact they had a booming solar industry, which got nuked by politicians, who changed the policies, as can be seen in 39C3 video "Recharge your batteries with us".
Was the subsidy system which was in effect in 2010's unsustainable? I think so, yeah. But the changed policies resulted in companies producing solar going bust, and the Chinese firms, which were doing fine, were able to buy out the patents and know how.
So, did Germany waste billions? Yes, but by letting the solar producers go bust.
Yeah, if you're buying a new car, electric makes sense if at all possible. But a lot of people are not buying new cars, because new cars are not cheap. There's a saying that a new car loses half of its value the moment it's driven away from the dealership.
But I agree, operational costs of an EV can be much lower, if you can charge at home rates.
They were deregulated on highway for a very long time. Deregulation came to off-highway in 2020 as the loss of demand due to covid made the prices drop. Rusian invasion of Ukraine and subsequent price hikes made the govt regulate the prices again.
Somewhere in between, a feud started between the largest provider Petrol and govt, and govt started regulating the highway prices too for no good reason.
The problem with getting rid of oil is that cars currently in use will be usable even when over 20 years old, replacing them with EVs is expensive, and the good enough and economically accessible EVs are only now starting to get to market.
It's really hard to quickly replace millions of vehicles.
Yes, but it is not enough. It helps a lot when sunny, and weekend mid-day gross market prices for electricity hover just above zero, but there's not enough batteries, flexibility, and other renewables to avoid price spikes in the morning and evening peak, when hydro and gas plants are still covering a lot.
It's not a free market. Off-highway prices are regulated and were adjusted by the executive govt branch on biweekly basis, now switched to weekly. Slovenia is small and "gas tourism" is common since fossil juices in neighboring countries are priced higher.
Why not raise the prices? Sure, but then don't complain about the inflation, revolt, and stoning of elected representatives.
Just spraying dust with water will not remove it. Detergent helps, but most of the cleaning effect is done by mechanical agitation, eg. wiping the glass.
The problem here begins even before the mathematical issue - it's that web sites that live from listing bookings have an incentive to offer a way to delete reviews that are not in line with what the owner wants to see.
You were commonly given a network uplink and a list of public IP addresses you were to set up on your box or boxes. IPMI/BMC were not a given on a server so if you broke it, you needed to have remote hands and probably brains too.
Virtualisation was in the early days and most of the services were co-hosted on the server.
Software defined networks and Open vSwitch were also not a thing back then. There were switches with support for VLANs and you might have had a private network to link together frontend and backend boxes.
Servers today can be configured remotely. They have their own management interfaces so you can access the console and install OS remotely. The network switches can be reconfigured on the fly, making the network topology reconfigurable online. Even storage can be mapped via SAN. The only hands on issue is hardware malfunction.
If I was to compare with today, it was like having a wardrobe of Raspberry Pies on a dumb switch, plugging in cables when changes were needed.
