Why calculate when we have lots of empirical data? There are plenty of grids around the world are deriving 40% of their energy from wind and/or solar. Up to 65% is relatively easily accommodated according to grid engineering orthodoxy

Not in my experience, unfortunately. I got a new XPS13 for work with Ubuntu pre-installed about 4 years ago and it was far from the "sweet spot". Hibernate/sleep didn't work out of the box (although the fix was relative

Good for you. I mean that without sarcasm. I most certainly am not and don’t consider myself Anglo-Saxon in any way although English is my mother tongue. I would consider referring to New Zealand (for example - not my home country) as “An

This is perhaps nitpicking but I wish non-native English speakers would not use the term “Anglo-Saxon” to describe anglophone or (better) English speaking countries. The term refers to the original north Germanic invaders of England and so

To my ear, to do something “spontaneously” means to do something without having planned it. So to make plans with someone to do something “spontaneously” sounds oxymoronish.

I don’t recognize the pattern you describe. For various reasons I’ve done a lot of travel over the last month or so - 2 “old money” European countries, a “new money” European country, a Middle Eastern country and Australia and I didn’t use

In college, we had to wire wrap an 8-bit (6809) CPU with an EPROM and UART to connect a terminal. It looked nothing like your image. A 16 bit address bus, 8 bit data and only RAM/ROM/UART sharing the "bus" meant that t

Varying output from a nuclear plant is mostly achieved by simply releasing the generated steam into the atmosphere instead of sending it through the turbine[1]. But operating a nuclear plant in this fashion pushes up the price per MWh consi

There is no "tremendous advantage" available to small countries in being able to devalue their currency. A currency devaluation may, in theory, make a country's exports more competitive but it does so by imposing a real cut o

I've wondered this also. I could understand the initial reluctance for western powers to supply such weapons. But the complexion of the war, it seems to me, has changed considerably with most Russian long range weapon fire now directe

I don’t see how the trajectory of emissions can differ from the trajectory of fossil fuel consumption. Yes electricity generation accounts for roughly a quarter of emissions - very roughly the other quarters are due to transport, domestic h

“That’s a certainty” - based on what evidence? Most indicators show that we have reached (or will reach within a year or two) peak global fossil fuel consumption. Even the EIA (who have been notoriously conservative in recognizing the tran

I also hope so. It’s not like the country can’t afford it. It’s hard not to view Norway and other big fossil fuel exporters as being analogous to cigarette companies. Everyone knows what you’re selling is poison but you get a pass because

Your terminology is confusing as I think you’re using technical terms (“trade”, “open”, etc) in a way that does not reflect their usual meaning. A “trade” generally refers to an event not state, while I think you want to refer to “position”

Perhaps off-topic but I use MuseScore 3 occasionally and it's great that there's a free alternative for amateurs like me who only use such software a few times a year. But it feels like it such a missed opportunity - it's 90

I can't see it. I've no idea what problem was solved by the current weird IEEE behavior. It must have been a biggy because this solution means your domain now loses the property that, in general, x == x. This property is a funda

Java has a specific hack for this which I discovered by accident a few years ago. Normally, given (primitive) double values d0 and d1, then boxing them does not affect equality testing - i.e. d0 == d1 if and only if Double.valueOf(d0).equa

I though my argument was clear - that you need back-up for nuclear power also? You accuse me of bad faith for quoting a number which includes both unscheduled and scheduled shutdowns by comparing with a number which only include the latter.

100% isn't the goal.. yet. Nor is it practical for many countries. But, getting to 70-80% renewables with current technology is feasible and economic for nearly all countries. The balance to be provided by modern (natural) gas turbi

You can no more rely on nuclear or coal generation for your electricity without back-up than you can on wind or solar. A nuclear plant in the US is off-line for 29 days a year on average according to the EIA. So you still need back-up for

The answer to your question "How long can we go without new gas?" would be a meaningless metric if not accompanied with a large amount of qualification. What is meant by "without new gas"? Without LNG shipments? Without

It's GWP over 100 years. This is stated in the source: "We estimate the hydrogen GWP(100) [ie, over a 100-year period] to be 11 ± 5; a value more than 100% larger than previously published calculations." In the past, I&#x27
