In the end, what matters is not so much the subsidies, but how countries will reach the 55% reduction of green house gasses in 2030. Of course subsidies have an effect on that. But these effect varies from country to country and from sector

Nuclear cannot do peak power in any affordable way. So it doesn't matter how reliable nuclear is, if there is not enough power in late afternoon/early evening then the grid is broken. Given the current costs for nuclear power, you

Nuclear, wind, solar, they all need storage. Wind and solar because sometimes there is no wind or sun. Nuclear because building out for peak capacity is unaffordable. But I responded to 'Nuclear uptime is orders of magnitude better tha

Google will still tell them 'I have X users interested in your product'. It is just that Google will compute that from the contents of the wedsite instead of from tracking users. It would be amazing if there would be no ads outsid

Can you explain the 'not looking good' part? I see in 2002, Gas+Oil+Coal+Nuclear = 450 TWh. Then in 2021 this amounts to 262.98 TWh. So both nuclear and fossil fuel went down quite a bit. Looking just at the fossil fuel number, th

Advertisers need content to advertise on. The GDPR basically forces content providers to get rid of tracking. That will require Google to provide an ad platform without tracking. And then the fun is over for the advertisers. Of course with

That would be a great outcome for the EU. It means that EU companies have a home market that is shielded from their biggest competitors, while being free to compete on the world wide market. If the EU would do that intentionally there would

Technically that is true. Economically, that means that if a nuclear power plant runs for significant amount of time at 50%, the price of electricity will almost double.

Capacity factor for wind at sea (North Sea at least) is typically above 40%. So nuclear can be at most a factor of 2.5 better. Given how cheap wind is, you can easily overbuild a factor of 2.5 and still be cheaper than new nuclear.

There are a number of issues: 1) Short term, the faster we avoid CO2 the better. If SLAs make that more complex, then it is a net loss. Long term, the situation will be different because cheap gains will be gone. 2) Europe has mostly privat

It's the other way around. Without wind and solar, Germany would produce a lot more CO2 than it produces today. If you come from a situation where most electricity is generated from fossil fuel, with a bit of nuclear, than installing a

It seems to be a combination of nuclear becoming too high tech combined with not enough volume to maintain the technology. Maybe its a scale thing. If you build only a few nuclear plants per decade, you can't iterate over designs. You

The problem we have is that in the past decade fossil fuel was way to cheap. This has now changed, but ramping up production of solar and wind takes a while. Fossil fuels are still way too cheap compared to storage of electricity. So there

The proof is that nobody is investing in keeping old nuclear power plants open. All over Europe. When those plants stay open it is governments paying for it. In contrast, companies are now paying money to rent a piece of sea to put a wind f

In The Netherlands, more than 90% of all homes is heated using natural gas. Part of that is historical, but also cooking on natural gas was for a long time the best solution. So if you run natural gas to every home anyhow, there is little r

The surprising thing is that with a rare exceptions (like in Finland) people who have money to invest don't believe that investing in nuclear power will actually make them a profit. We know the price of CO2 will just go up and up. We k

by phicoh 5y ago
You have to compare district heating to about 7 million households using natural gas for heating in The Netherlands alone. So keeping a few nuclear power plants open has hardly any effect on the amount of natural gas that is used.

Ultimately, this is about money. For aging nuclear power plants, keeping them running becomes more and more costly. So the question becomes, if we need to invest a big chunk of money, what should we invest in to reduce CO2 emissions the mos

It is very simple, nuclear has been a failure in Europe in the last couple of decades. Look at projects in the Finland, France and the UK. The situation would have been much better if there was a nuclear industry that could deliver in time

The problem is simple. For decades, Russia was supplying natural gas reliably and for a reasonable price. Generating electricity with natural gas is trivial. So shutting down old nuclear power and replacing it with wind/solar backed up

Just a random guess. The security of TLS-ALPN-01 relies on TLS implementations rejecting a connection if an unknown ALPN is present. It is possible that TLS 1.1 and earlier do not require this behavior leading to exactly the SNI confusion t

FreeBSD creates a branch off current very close to a major release. So work for a new major release happens on current. At some point current blocks new features and focusses on fixing bugs. Then a branch for the major version is created an

That's the thing. When C is portable assembler, you expect signed integer overflow to be the same as in assembler. On x86 you don't expect a trap. There are quite a few idioms where overflow is used intentionally. There is no reas

C89 is mostly a superset of K&R C. So if you can write an OS in K&R you can write it is C89. The issue was, do modern operating systems require newer versions of the C standard? Or can you write everything in C89.

Rust can be hard to write, but by and large is not hard to read. Rust does have more abstraction mechanisms than C. So it is possible to go overboard in that area. But that is more a coding style issue. C programs that nest multiple levels

Assuming that an early Unix clone would be written in C plus some amount of assembler. Then what constructs of modern Unix systems make it impossible to in write in the first ISO C standard plus some assembler? For example, 4.4BSD, early So
