Measuring AC supply frequency

In other countries there are also similar agreements between network operator and industry. There can be years between situations in which such agreements are activated.

In the UK, is such agreements activated multiple times a year ?

In a well managed network, there are a number of fast starting gas turbines with total capacity larger than the largest single (nuclear) power plant. If the largest unit fails, these gas turbines are started within minutes.

However, if all emergency gas turbines are running as a result of a single big failure, the network doesn't tolerate an other big failure.Either the output power of existing power plants must be increased (or started) or some big lads has to be removed within an hour, so that the emergency gas turbines can be stoppled and be ready for the next big failure.

These emergency gas turbines are expensive to run with natural gas and their efficiency is low, so you do not want to run for a long time.

For these two reasons these emergency gas turbines are used for les than a few hundred hours each year.

Even if most energy in the network is produced with unreliable renewables, some emergency gas turbines should still be available. The question is how these are going to be fueled e.g. with bio methane or natural gas even if the climate alarmists think it is a bad idea to use NG.

There are very few mountains in Texas.

If inciting a race war or gender war can achieve the first step - so be it. Americans have to be blind not to see what has now begun there.

Not for quite a while now. The Soviet invasion of Hungary in 1956, disillusioned most of the remaining communist party supporters outside the USSR.

The international socialist movement has thrown out Karl Marx and the proto-communists in 1871 for promoting non-democratic government which was likely to degenerate into a tyranny. When it did in the USSR there were quite a few socialists who noticed and complained about it. By the time people like George Orwell had joined in it was pretty much mainstream leftism.

Quite how Phil Allison has managed not to notice this is a mystery. He is remarkably ill-informed in a lot of areas.

Gender dysphoria is a remarkably rare condition. Imagining that anybody could be bothered to start a war about it is a trifle unrealistic.

The return of more or less sane government? Some of our resident US lunatics seem to resent being deprived of their regular dose of moronic lies - Jon Doe and Flyguy come to mind - and seem to want to fill in the prevarication gap. You too seem to have joined the mis-information party, and don't even have an American education to blame for it.

The United States is at 46 on that particular league table with 79.11 years. Italy, Spain and Australia are at sixth, seventh and eighth with about 84 years.

Once you join the rest of the advanced industrial countries in adopting universal health care you may do better, but at least some of the problem is your gross inequality in incomes, which is way worse than the rest of the advanced industrial countries. If you were prepared to collect more of your gross domestic product in taxes you might be able to do better, but you cheapskate on education for the less well-off, which gets in the way. People who are as dumb as you are, and as resistant to getting better informed, aren't going to want to improve anything. They don't know enough to realise that anything needs improvement.

I've hung around with psychologists for most of my life, and none of them think that I'm autistic. Phil Allison - who has never met me face to face, and seems to know very little about the subject - is convinced that I am. I'm sane enough to listen to people who do know what they are talking about rather than some rabid obsessive who thinks that everybody except him is autistic.

This is perfectly rational and well-founded denial.

But shared by the rest of the world.

"According to the Australian Bureau of Statistics (ABS) Survey of Disability, Ageing and Carers (SDAC), an estimated 164,000 Australians had autism in 2015 (ABS 2016). This represented an overall prevalence rate of 0.7%, or about 1 in 150 people. The number of people with autism in Australia has increased considerably in recent years, up from an estimated 64,400 people in 2009 (ABS 2014). The prevalence of ASD is reportedly growing at a faster rate than any other disability."

The prevalence does seem to be rising, but not all that much - people are more willing to diagnose it than they used to be, in part because we've become better at managing it, and it's worth treating kids with the kind of mild autism that isn't actually disabling, but can be inconvenient.
